There is a growing risk that the United States and its allies could face scenarios in which one or more adversaries might resort to nuclear weapons use in a regional conflict. This risk is especially evident in Russian strategic theory and doctrine, which envisions regional deterrence as complementing global deterrence. Some Russian military experts see the potential use of nonstrategic nuclear weapons for “de-escalation of military actions and their termination on conditions favorable to the Russian Federation,” or “a demonstration to the enemy of resolve to defend [Russia’s] interests by escalating the use of nuclear weapons (tactical) and forcing him to forego further aggression by the threat of use of strategic nuclear weapons.” Statements by North Korean leader Kim Jong-Un indicate that the country’s nuclear arsenal is also intended for deterrence in a regional conflict, such as a potential decapitation strike. Moreover, China has been rapidly expanding its nuclear arsenal for both military reasons and to gain geopolitical leverage, as argued by Tong Zhao, such as upholding its “core interests” in Taiwan.
+ +Due to these growing risks of regional crisis escalation with potential for nuclear use, U.S. decisionmakers are revisiting the concept of intra-war deterrence, which is about influencing enemy actions during an ongoing conflict. The risks of deterrence failure have been a focal point in the testimony of recent U.S. Strategic Command (STRATCOM) commanders, including Admiral Charles Richard, who noted in 2020 that STRATCOM conducted analysis into the risks of strategic deterrence failure, and General Anthony Cotton, who said, “We must be ready if deterrence fails” in testimony in February 2024. Intra-war deterrence operates on the premise that in an active conflict, threats can be leveraged to shape an adversary’s actions and set boundaries on the intensity and nature of military engagement. This concept underpinned much Cold War strategic thinking. One fundamental challenge of intra-war deterrence is how to balance deterrence objectives with war-fighting objectives. As W. Andrew Terrill writes regarding the mismatch of these objectives, “a state pursuing such [an intra-war] policy is waging war against another nation while seeking to prevent its opponent from responding with all of the weapons that it possesses. Such a task is . . . challenging since both sides usually seek to use as much of their capabilities as possible to optimize their chances of victory.”
+ +To assist in this thinking and to develop actionable insights for the U.S. policy and strategy communities, the Project on Nuclear Issues (PONI) invited a group of experts to develop competing strategies for responding to strategic deterrence failure. This study revives a concept and approach that the Center for Strategic and International Studies (CSIS) developed a decade ago to review U.S. nuclear strategy and posture for 2025–2050. The project’s current contributors were each asked to respond to a scenario involving near-simultaneous battlefield nuclear use by Russia and China. The strategies focused on four specific themes: strategic objectives, assurance to allies, military responses, and non-kinetic responses. The strategies demonstrate agreement on key issues, such as the importance of deterring conventional aggression and the relevance of non-kinetic responses to adversary nuclear use. But the strategies also highlight important areas of disagreement about the relative importance and feasibility of assuring allies, at least relative to other strategic objectives; the advisability of a nuclear versus conventional response to deterrence failure; and what “winning” in a strategic deterrence failure scenario would look like. While many people may disagree with these positions, PONI welcomes a diverse range of views, which can help foster a robust debate. CSIS does not take an institutional view, and the views presented here are those of the individual contributors.
+ +After providing an overview of the authors’ competing strategies, this chapter presents the project’s guiding assumptions and analytic framework. This introductory analysis then distills three principles for intra-war deterrence: establishing (or maintaining) regional deterrence, restoring assurance, and planning precrisis for intra-war deterrence. These principles capture areas of consensus among the strategies while also engaging with areas of disagreement in order to identify which policy options are best suited for the current strategic environment.
+ +As a foundation for Project Atom’s analysis, PONI provided the authors a scenario that features concurrent nuclear aggression from the People’s Republic of China (PRC) and Russia. The scenario, set in 2027, is predicated on the following assumptions:
+ +Xi Jinping and Vladimir Putin remain the leaders of the PRC and Russia, respectively.
+The PRC and Russia have not relinquished their territorial claims — that is, the PRC continues to pursue “reunification” with Taiwan, and Russia maintains its claims on annexed Ukrainian territory.
+The war in Ukraine continues as a stalemate. Western aid for Ukraine continues.
+Western sanctions damage the Russian economy and drive continued economic cooperation between Russia and the PRC.
+Russia manages to partially rebuild its conventional military despite low GDP growth, related financial challenges, and ongoing fighting.
+PRC GDP growth stabilizes between 3 and 4 percent, compared to the United States’ approximately 2 percent. The two economies remain deeply intertwined.
+The United States and its allies proceed with their planned defense modernization and preparedness efforts. The United States forward deploys additional forces to Europe and the Indo-Pacific.
+By March 2027 in this scenario, Taiwan’s domestic political landscape has shifted decisively against reunification. In response to pro-independence statements from Taiwanese presidential candidates, PRC officials begin to publicly discuss using military force to achieve reunification. In the ensuing weeks, the U.S. intelligence community observes the beginnings of a PRC military buildup in Fujian Province.
+ +Around the same time as this buildup, Xi and Putin host a summit at which Putin voices support for the PRC’s position on Taiwan. The two leaders announce joint naval drills in the Pacific to coincide with Russian conventional and nuclear exercises near Russia’s Western borders in mid-May.
+ +In preparation for what they consider an imminent threat, the United States and its allies signal that “wars of conquest will be punished” and bolster their defensive postures through expanded forward deployments and elevated readiness levels in both Europe and the Indo-Pacific. In the weeks preceding the joint PRC-Russian exercise, a Ukrainian offensive makes significant gains and threatens Russian control of Crimea.
+ +On May 14, the joint PRC-Russian naval exercise begins in the Western Pacific. The following day, the PRC begins missile strikes on Taiwan in preparation for a full-scale invasion. On May 16, Russia conducts conventional missile strikes against Polish transportation infrastructure. Xi and Putin release statements justifying their own actions and supporting the other’s.
+ +NATO promptly invokes Article 5, and the United States and its allies begin highly successful conventional campaigns against the PRC and Russia. In the Indo-Pacific, U.S. and allied forces interdict PRC landing craft before they reach Taiwan. Heavy People’s Liberation Army (PLA) casualties prompt limited anti-mobilization protests across China. In Europe, Polish and Lithuanian forces push into Kaliningrad Oblast and threaten to seize Kaliningrad City. NATO states begin to deploy forces to Ukraine, while Ukrainian forces advance with NATO assistance and prepare for an invasion of Crimea.
+ +On June 2, Russia strikes Polish transportation infrastructure and NATO forces threatening Kaliningrad with low-yield (< 10 kt) nuclear weapons, inflicting approximately 1,000 casualties (including some Americans). Putin warns NATO of “total annihilation” if it does not cease its “aggression.” On June 3, the PRC conducts a 50 kt nuclear strike on a U.S. naval base in the Philippines, resulting in 15,000 casualties. Xi Jinping warns that “Anyone aiding the splitists in Taiwan . . . will face the wrath of a people determined to rejuvenate their nation at any cost.”
+ +The PONI team provided experts with four framing assumptions and respective guiding questions as an analytical framework, which are discussed later in this introduction. This report contains five chapters, each of which constitutes a distinct strategy for intra-war deterrence. A comparison of the strategies across the analytical framework is provided in Tables 1–4; discussion of the framing assumptions then follows.

+ +U.S. STRATEGIC OBJECTIVES
+ +Assumption #1: In the event that strategic deterrence fails and an adversary has used a single or multiple nuclear weapons, the United States will be forced to confront competing priorities to uphold security commitments to allies, manage further escalation, and resolve the conflict on terms favorable to the United States. The adversaries may assume they have more at stake in a regional crisis than the United States and thereby question U.S. resolve. This raises the following questions with regard to U.S. strategic objectives in the event of strategic deterrence failure:
+ +In what ways, if any, did the United States fail to demonstrate resolve and commitment to its strategic objectives in the lead-up to nuclear use? Why did deterrence fail? Could anything have been done to prevent strategic deterrence failure?
+What are the United States’ core objectives in this scenario, and how should the United States prioritize its strategic objectives? Is one area of operations more important than another in this scenario?
+What does “winning” look like? How would the United States know if deterrence has been “restored”?
+Identifying and prioritizing strategic objectives will be critical following adversary nuclear use, and this will require understanding why deterrence failed. Authors reached different conclusions on this point. Ford, on one hand, concludes that deterrence failed because of adversary perceptions about U.S. credibility that had built up over years. He argues that there may have been nothing that U.S. policymakers could have done to deter adversary aggression in the immediate run-up to the crisis. Panda, on the other hand, points to the swift defeat of adversary conventional forces as a primary driver of escalation, adding that the adversary may believe that limited nuclear use can deter the United States from further involvement. Weaver suggests that the United States may have failed to credibly signal its resolve to defend its allies and partners but acknowledges that deterrence failure may have alternatively stemmed from adversary miscalculations about their abilities to fight and win conventional conflicts against the United States and its partners.
+ +While the authors agree about the importance of avoiding full-scale nuclear war following deterrence failure, they disagree about the relevance and prioritization of other strategic objectives. Sisson, for example, identifies only two U.S. strategic objectives: preventing general nuclear war and preventing further nuclear detonations of any type in any location. Similarly, Panda writes that “no objective should be greater for the president of the United States than ensuring that the survival of the country is not threatened by the prospect of uncontrollable escalation into a general nuclear war.” Ford and Gibbons also both list avoiding nuclear war as the primary U.S. objective but identify a range of secondary strategic objectives, including denying the adversary battlefield victory, denying the adversary any advantage specifically from having used nuclear weaponry, and maintaining alliance relationships. Conversely, Weaver lists four strategic objectives: (1) restoring the territorial status quo ante; (2) restoring nuclear deterrence; (3) avoiding general nuclear war; and (4) denying the adversary any benefit from nuclear use.
+ +ASSURING ALLIES
+ +Assumption #2: The United States will remain committed to allies’ security and their vital national interests in the event of strategic deterrence failure. For example, if NATO Article 5 is invoked, the United States will respond. Therefore, at least one U.S. objective (from above) will be continuing to assure and demonstrate credibility and resolve to allies. Partners, however, remain in a somewhat ambiguous position in the event of direct military attacks or nuclear strikes. This raises the following questions with regard to allies and partners in the event of strategic deterrence failure:
+ +What are the risks — and their likelihoods and potential consequences — of allies questioning U.S. credibility in the event of strategic deterrence failure?
+What will be allies’ security concerns in the event of strategic deterrence failure? What role might certain allies and partners play in a response?
+How can the United States signal resolve to allies in the event of strategic deterrence failure? How does this differ from signaling resolve to non-treaty partners?
+Based on their differing assessments about the most pressing U.S. strategic objectives, the authors disagree about the importance and feasibility of assuring allies following adversary nuclear use. Panda argues that, given that any U.S. president is likely to prioritize protecting the U.S. homeland above all, severe damage to U.S. credibility is a forgone conclusion in the event of strategic deterrence failure. He writes that the United States would face “insurmountable” assurance and credibility challenges following nuclear use and that “it is highly likely that following strategic deterrence failure, allied perceptions of the credibility of the United States would suffer drastically.” Sisson suggests that the defense of Ukraine and Taiwan should be a primary U.S. war aim but maintains that avoiding further nuclear use of any type should be the United States’ first objective.
+ +Ford, Gibbons, and Weaver, on the other hand, argue that assuring allies should be one of the United States’ primary strategic objectives. Ford and Gibbons both suggest that a nuclear response to deterrence failure is not necessary to reassure allies. Ford writes that the United States is not obligated to use any specific weapons in defense of its allies, as long as it does effectively defend them against aggression. He also argues that that, on the facts of the scenario, “continuing to prosecute a successful conventional campaign” and deny the adversary any benefits from nuclear weapons use “should represent an optimal answer from U.S. allies’ perspectives.” Weaver offers that the U.S. response that deters further aggression while avoiding uncontrollable escalation will be the optimal response from an allied perspective.
+ +MILITARY RESPONSE OPTIONS
+ +Assumption #3: The president will consider a combination of kinetic and non-kinetic response options in the event of strategic deterrence failure. Options might include the use — or explicit threatened use — of nuclear weapons, naval deployments, or boots on the ground. This raises the following questions with regard to military response options in the event of deterrence failure:
+ +What would be the president’s military options in the event of strategic deterrence failure? Which of these options would you recommend to the president?
+What are the risks associated with a military response?
+What are the signaling objectives of military response options? How will these options contribute to conflict termination on terms favorable to the United States?
+In the event of strategic deterrence failure, how strictly should the United States observe the law of armed conflict (i.e., principles of proportionality and discrimination)? How much should it influence the strategy?
+While the authors agree on the need for some form of military response to adversary nuclear use, their proposed responses differ significantly. Panda, Ford, and Gibbons each recommend conventional responses to adversary nuclear use. Gibbons and Panda endorse conventional strikes against the adversaries’ forces that were directly responsible for nuclear strikes against U.S. partners and allies. Though he argues that the United States needs to be prepared to use nuclear weapons if the adversaries were to use them again, Ford suggests that U.S. and allied forces should “fight through” adversary nuclear use here and continue their already successful conventional campaigns with slight changes in posture to better prepare for the possibility of further adversary nuclear use.
+ +Weaver is the only author to propose a nuclear response. He concludes that a conventional response would be problematic for several reasons, including that it may simply encourage adversaries to escalate further.
+ +Sisson proposes the most restrained response to adversary nuclear use. She suggests that, to avoid further escalation, U.S. and allied forces should cease offensive military operations and look instead to hold the line against further adversary aggression and rely on non-kinetic options.
+ +NON-KINETIC RESPONSE OPTIONS
+ +Assumption #4: The U.S. political and military leadership would consider non-kinetic response options across the diplomacy-information-military-economics (DIME) spectrum. Many of these capabilities might overlap across domains, and the authors were given discretion to decide what are military versus diplomatic, information, economic, or other non-kinetic response options. Possibilities such as economic sanctions, building international pressure, or information operations would likely be part of the U.S. response to a strategic deterrence failure. This raises the following questions with regard to non-kinetic response options in the event of deterrence failure:
+ +What would be the president’s non-kinetic options in the event of strategic deterrence failure? Which of these options would you recommend to the president?
+What are the risks associated with a non-kinetic response?
+What are signaling objectives of non-kinetic response options? How will these options contribute to conflict termination on terms favorable to the United States?
+The authors generally agreed about the importance of non-kinetic measures in responding to adversary nuclear use. One area of commonality was the importance of non-kinetic deterrence efforts prior to nuclear use during the crisis. Most suggested some form of information warfare or targeted messaging to accompany their proposed military responses, as well as non-kinetic military measures and economic retaliation. Weaver, for example, proposes information operations to maximize international backlash to adversary nuclear use and convince the Russian and Chinese people that their governments’ actions risk large-scale nuclear war, as well as measures to impose economic costs on Russia and China. Ford, Gibbons, Sisson, and Panda each suggest cyberattacks against adversary forces, as well as economic retaliation. Moreover, Gibbons, Sisson, and Panda advocate for diplomatic messaging to the international community to build a coalition condemning Russian and Chinese nuclear use. Panda proposes intelligence declassification as a tool to counter adversaries’ information operations.
+ +Based on the expert papers, the PONI team identified three broad principles for thinking about and planning for intra-war deterrence in a two-peer environment. At the outset, however, it is worth observing that intra-war deterrence is highly context dependent, and many of the recommendations of these papers might not be applicable to other intra-war deterrence scenarios, to include whether to respond with nuclear or conventional weapons and how to assure allies. The stakes will depend on the context. In the scenario provided here, what is at stake is allies’ sovereignty and security and U.S. global leadership, but these must be balanced with the stakes of escalation, which could include further humanitarian consequences depending on whether conventional or nuclear weapons are used.
+ +INTRA-WAR DETERRENCE REQUIRES REGIONAL DETERRENCE
+ +In these scenarios, America’s adversaries are acting on the belief that they have more at stake in the region than the United States. Ford describes the strategic challenge: “Both of these failures [are] likely derived from assumptions in Moscow and Beijing, not that Western leaders lacked the capacity to respond effectively, but that they lacked the will . . . . It is the primary task of intra-war deterrence here to convince them that this, too, was a misapprehension.” As demonstrated by all of the papers in this volume, the United States will need a diverse and flexible tool kit, to include regional nuclear capabilities and conceal/reveal capabilities.
+ +While only one of the papers calls for the United States to respond with nuclear weapons, nearly all of the authors acknowledge the importance of the United States having a breadth of nuclear response options. For Panda, this is largely tied to assuring allies because “it is highly likely that following strategic deterrence failure, allied perceptions of the credibility of the United States would suffer drastically unless Washington opted for nuclear use in kind,” although he expresses concerns with risks of escalation. For Ford, amid a conventional response, “U.S. nuclear weapon storage vaults at relevant European airfields should also be readied for potential operations, and any existing plans for weapon dispersal to additional airfields that do not involve actual DCA attack assets should be implemented.”
+ +These and other points make a case for the United States to improve its regional deterrence posture through increased regional capabilities and flexible options in order to prepare for a proportionate nuclear response in a limited-use scenario. U.S. policymakers should strive to diversify U.S. nuclear forces through investments in new regional capabilities so that the president will have a broader range of credible options, particularly if an adversary threatens limited nuclear attacks. The capabilities should be survivable, lower yield, and responsive and effective across a spectrum of targets. Strategic deterrence is, and should remain, the primary mission of the U.S. nuclear force, and the triad is essential to the success of that mission. These capabilities will play a deterrence function not only during a crisis but also beforehand, as argued by Weaver:
+ +++ +If the effect of selecting a nonnuclear response to adversary nuclear escalation is to convince the adversary that the United States is so concerned about uncontrolled escalation that it fears responding in kind, then a U.S. nonnuclear response could actually increase the risk of eventual uncontrolled escalation. This may seem counterintuitive, but if a U.S. nonnuclear response to adversary limited nuclear use results in encouraging further adversary nuclear escalation, then the U.S. nuclear responses that may eventually be required to achieve U.S. objectives are likely to be larger in scale and more provocative in their effects. This could well make uncontrolled escalation more likely.
+
Another option for re-establishing deterrence would be relying on conceal/reveal capabilities, such as demonstrating a previously unknown capability amid a crisis to inspire the adversary to exert caution. As described by Weaver, “There is a potential role here for the calculated revelation of capabilities the adversary was previously unaware of that have potentially decisive military effects (‘You didn’t tell me they could do that. What else don’t I know?’).” Conceal/reveal capabilities could also offer U.S. decisionmakers more flexibility in a crisis, as well as having a powerful deterrence impact when needed most to de-escalate a crisis.
+ +RESTORING DETERRENCE REQUIRES RESTORING ASSURANCE
+ +As multiple authors identify, a strategic deterrence failure could inspire a crisis of confidence among U.S. allies and partners. While some of the papers in this volume call for reconsidering U.S. security commitments to allies in a crisis, this would be a mistake for both short- and long-term reasons. Amid the ongoing conflict, the United States would need allies to fight through a scenario such as the one outlined in one or both theaters. While Ford argues that the Indo-Pacific theater is the more important of the two, he notes that “a Western loss in the European theater” would still be “a disaster.” For him, “[j]ust as the United States prioritized defending Europe from the Nazis in World War II without backing off against Japan in the Pacific, even if the United States must now prioritize East Asia in certain ways, it should not abandon Europe.” Ford, for example, points to the importance of European allies in leading on conventional fighting and re-establishing deterrence in one theater while the United States focuses on the Indo-Pacific. For Weaver, “If U.S. responses to initial Russian or Chinese escalation make clear that the United States is willing to engage in a competition in dire risk-taking, and that Russia and China must also fear potential uncontrolled escalation, allies are likely to be reassured in the near term.” Over the long term, alliance structures would be an essential component for any eventual peace settlement and post-conflict international order, assuming a U.S. objective is to maintain global leadership, as argued in nearly all of these papers.
+ +Gibbons points to an additional value of maintaining and assuring allies: they can play a crucial role in generating international condemnation aimed at deterring further nuclear use by the adversaries:
+ +++ +Allies and partners have a significant role to play in the messaging following nuclear use. They must unite in loudly and publicly condemning the nuclear attacks and should do so repeatedly. They should communicate that using nuclear weapons in these scenarios was unacceptable and neither nation will gain from using these weapons. These messages are key to reestablishing the nuclear taboo following nuclear use.
+
Gibbons goes on to make the case for U.S. policymakers to immediately engage the U.S. public on the importance of allies, for example. The United States could also develop an engagement plan for deepening planning and consultations with allies on potential battlefield nuclear use and opportunistic aggression scenarios. A series of mini tabletop exercises could begin familiarizing allied and U.S. government officials across the interagency, including at the Department of State, the National Security Council, and the Department of Defense (including combatant commands) with how deterrence works and how battlefield nuclear use might impact both conventional campaigns and deterrence dynamics.
+ +INTRA-WAR DETERRENCE WILL DEPEND ON PRECRISIS PLANNING AND DECISIONS
+ +Finally, intra-war deterrence will largely depend on precrisis decisions and planning. These comprise decisions and actions taken with adversaries, allies, domestic audiences, and wider international ones. Examples include dialogue with allies about crisis communication and decisionmaking, conceal/reveal capabilities, and establishing thresholds and threats (i.e., do not bluff). There are at least two main areas where the United States can focus on intra-war deterrence planning before a crisis begins: strategic communications, particularly with international audiences, and wargaming.
+ +Shaping narratives and messaging before and during crises will be essential. Such messages will need to be tailored to multiple audiences: allies (focusing on assurance), domestic audiences (focused on the importance of U.S. alliances, and in support of achieving U.S. military responses to adversarial limited nuclear use), international audiences (aimed to “make the adversary a pariah,” as Weaver argues), and adversarial domestic audiences (meant to foment a facts-based public consensus). When facing a crisis involving potential limited nuclear use, strategic communication must be multifaceted. Messages must be tailored to diverse audiences (allies, the U.S. public, the international community, adversary leadership, and their citizens) and adapted for each stage of the crisis, including preemptive communication. For example, before a crisis, messages aimed at the U.S. population should focus on the importance of alliances. As Gibbons argues, “Before any potential conflict — and frankly, right now — the U.S. government, especially the president, should aim to better educate the public about the history of U.S. alliance relationships and their benefits.” Precrisis messaging to Americans could also focus, for example, on reassuring the U.S. public about U.S. commitment to deterrence and the limited nature of any potential nuclear response.
+ +Precrisis engagement with international audiences (particularly the Global South and “non-aligned” states) was raised in several analyses. Gibbons writes:
+ +++ +It is worth emphasizing here that improving U.S. and allied relations with states within the Global South before this notional conflict in 2027 is paramount. Though the international community broadly supported the 2022 UN General Assembly resolution condemning Russia’s attack on Ukraine, there have been fewer governments that have unilaterally condemned the attack or Russia’s nuclear saber-rattling, even among members of the Treaty on the Prohibition on Nuclear Weapons, a treaty that explicitly bans nuclear threats.
+
A second priority for precrisis intra-war deterrence will be more wargaming. One way to address this challenge is with more wargames through all stages of escalation, as highlighted in Weaver’s paper in particular. But Sisson also writes, “Each phase of a scenario exercises the thought processes involved in aligning military operations with war aims, and war aims with strategic objectives, under conditions in which some variables that might affect the likelihood of success are foreseeable and controllable and some are not.” Variations of these aims, objectives, and conditions can be explored through wargaming or other exercising. One particular scenario that would be worth exploring is coordination among allies, which is somewhat ambiguous in the scenario used for this study. Even with additional gaming and empirical data, however, there will be limits on knowledge about what happens after nuclear use and how to re-establish strategic deterrence.
+ +As Weaver argues, “Detailed wargaming and simulation is needed to analyze the ways in which limited nuclear use by both sides affect the course of twenty-first-century conflict and escalation dynamics across a range of scenarios and strategic circumstances. Without such analysis, U.S. efforts to identify the range of nuclear options needed to address limited nuclear escalation will risk missing key insights.” More comprehensive wargaming of the central problem could require asking these same questions across a set of plausible scenarios that span the range of key strategic circumstances the United States might face. Examples of other scenarios that should be examined using the Project Atom 2024 methodology include
+ +Conflict with Russia while deterring Chinese opportunistic aggression
+Conflict with China while deterring Russian opportunistic aggression
+Conflict with Russia and China in which the United States is winning conventionally in one theater and losing in the other when deterrence of limited nuclear use fails
+Conflict with Russia and China in which the United States is losing conventionally in both theaters when deterrence of limited nuclear use fails
+The full range of scenarios farther into the future when China is a nuclear peer
+It is worth acknowledging that even with additional gaming and empirical data, there will be limits on knowledge about what happens after nuclear use and how to re-establish strategic deterrence. However, analysis of additional scenarios and circumstances would likely produce new and important insights regarding the four key issues addressed in this project, to include opportunities for de-escalation and identifying off-ramps.
+ +There are a host of other opportunities for strengthening intra-war deterrence before a crisis begins. The United States and its allies may have to be prepared to fight and operate in a chemical, biological, radiological, or nuclear (CBRN) environment, which will require troop protection, equipment, and training. These preparations could also serve a deterrent function by demonstrating U.S. commitment to prevailing in defense of its allies, even in a CBRN environment.
+ +To state the obvious, contemplating how to respond to nuclear weapons use and strategic deterrence failure is deeply uncomfortable. Such a scenario could involve hundreds of thousands (perhaps millions) of casualties, environmental disasters, and the potential for further damage. Indeed, Sisson’s paper starts with the assumption that any nuclear detonation could quickly escalate to civilization-threatening general nuclear war. Ideally, the international community would condemn such attacks and impose heavy costs. But the United States also needs to be prepared to restore deterrence and end the conflict on terms favorable to the United States and its allies. In many of these scenarios, allies’ sovereignty is at stake.
+ +This report’s recommendations point to an urgent need for renewed engagement among policymakers and publics on nuclear issues. The stakes could not be higher, as it is the risk of repeated nuclear exchanges as well as the United States’ global leadership and credibility that are on the line. More regional nuclear capabilities will give U.S. planners more rungs on the escalation ladder for restoring deterrence without resorting to large-scale exchanges. They will also give the U.S. president more options in the event of a horrific scenario such as the one outlined here. A future U.S. president must be willing and able to employ nuclear weapons in response to a strategic deterrence failure scenario — and will therefore require flexible, limited options to navigate a scenario of limited nuclear use effectively. Whether a conventional or nuclear response to adversary nuclear use will be more effective in re-establishing deterrence and achieving U.S. objectives will depend on adversary motivations and the specific context of deterrence failure; while a nuclear response may be appropriate in certain scenarios, the same response could be unnecessary and escalatory in others. It is critical, however, that a U.S. president be able to employ whatever military response they determine to be most effective. The United States may therefore benefit from a more diverse nuclear force with a wider range of theater nuclear capabilities. Strategic investments in modernizing, diversifying, and enhancing the resilience of existing deterrent forces will strengthen deterrence and help avoid intra-war deterrence scenarios in the first place. By anticipating scenarios in which adversaries escalate regionally, potentially concurrently, the United States and its allies can strengthen deterrence and reduce the likelihood of adversaries exploiting perceived weaknesses. Preparing for multiple scenarios is not about seeking war but about enhancing deterrence to prevent it altogether.
+ +In addition to these capability considerations, U.S. decisionmakers can start laying the groundwork now for intra-war deterrence, to include increased and improved wargaming and tabletop exercises, including with allies. And U.S. military and strategic planners, along with policymakers, must immediately consider the question of how to restore assurance alongside deterrence.

The following pages respond to questions posed by the organizers of Project Atom 2024.
+ +ASSESSING DETERRENCE’S “FAILURE”
+ +The locus of deterrence “failure” here may lie not so much in the specific run-up to the crisis outlined in Project Atom 2024, but potentially years earlier. In this scenario, U.S. and allied leaders were stepping up their military preparedness before war broke out, and were very clear publicly that “wars of conquest will be punished.” Western posture and policy statements, in their own terms, left little basis for U.S. adversaries’ apparent conclusion either that: (a) the United States would not contest aggression in the first place; or (b) the United States could be frightened into intra-war concessions by adversaries’ use of nuclear weapons.
+ +Rather, irrespective of what the United States declared in the run-up to war, U.S. adversaries seem to have assumed that the United States and its allies were: averse to war in general; incapable of waging war effectively or on a sustained basis; and sufficiently afraid of nuclear escalation that Beijing and Moscow could enjoy the benefits of aggression without facing prohibitive risk. This assumption would appear to be rooted not in assessments of specific Western actions undertaken in this scenario, but rather in antecedent beliefs, accumulated over time, about fundamental weaknesses and risk-aversion in Western leadership and societies, coupled — presumably — with the conclusion that the aggressors could draw upon greater resources of martial seriousness and societal stamina in waging war, and that the stakes involved in each theater favored the nearer, “hungrier” power over the distant and more diffident United States and its weak and degenerate local friends.
+ +Deterrence of this aggression, in other words, arguably failed in Project Atom 2024 much the same way that deterrence of Russia’s 2022 attack on Ukraine failed not in 2021–22 but in 2014 — when Vladimir Putin, observing Western reactions to his annexation of Crimea and invasion of the Donbas, seems to have concluded that they would not react forcefully “next time” either. In the scenario presented here, the failure was twofold: the United States and its allies failed to deter Russia and China from undertaking wars of conventional military aggression, and then further failed in deterring them from using nuclear weapons when things on the battlefield began to go bad. Both of these failures likely derived from assumptions in Moscow and Beijing not that Western leaders lacked the capacity to respond effectively, but that they lacked the will — and hence were more tied to general and longer-term adversary assessments than to specific U.S. or allied posture and signaling failures in the run-up to the crisis.
+ +If so, this suggests that the efficacy of deterrence lies not only in clear military postures and public messaging, but also in an adversary’s underlying, longer-term assumptions about the character, motivation, and sociopolitical support enjoyed by those adopting such postures and sending such signals. If the adversary power has concluded that one is fundamentally timid and conflict averse — or simply unable to wage a war with resolution and commitment anyway — that adversary is less likely to be deterred by short-term precrisis signals even if they do, on their face, convey admirable resolution.
+ +Nevertheless, the more immediate problem for Western leaders in this situation lies not in addressing such deeper challenges but in managing escalation risks and restoring deterrence now that bullets have started flying.
+ +If U.S. adversaries assumed that the West’s sociopolitical weakness and fears of nuclear escalation would preclude its responding effectively to conventional aggression by a nuclear-armed great power in this scenario, of course, they were wrong. Since they also seem to have assumed that even their very limited tactical use of nuclear weaponry would scare the United States into abandoning its response to their aggression, it is the primary task of intra-war deterrence here to convince them that this, too, was a misapprehension. To the degree that the United States can do this, it has a chance not merely to manage this scenario, but also to help shape U.S. adversaries’ more general perceptions of the United States in ways that will enable maintaining deterrence once peace is restored. (After all, it is much less plausible to argue that a country will not fight you next time when it has just surprised you, this time, by demonstrating that it actually will.)
+ +CORE U.S. OBJECTIVES IN THIS SCENARIO
+ +Given the potentially existential implications, the first U.S. objective here is to avoid escalation to a full-scale nuclear exchange with either Russia or China. It would be a mistake, however, to conclude from this that the best way to achieve this requires backing down, or that this is the United States’ only important objective. On the contrary, making no response to the Russian and Chinese use of nuclear weapons in this scenario — or acting in a way that would reward such use with terrified Western de-escalation and hence cede theater-level advantage (or even victory) to the aggressor or convince that aggressor that the United States was abandoning its commitments to its allies — may actually increase the risk of broader war and even a full-scale exchange sooner or later, more than would a response of judicious firmness that denies them such benefits and makes clear that the United States stands with its friends and is not entirely unwilling to turn up the heat further.
+ +The United States has at least two second-order, but nonetheless extremely important, objectives in this scenario. First, it has an incentive to deny Russia and China victory in these regional conflicts (even in conventional terms) and to make good on U.S. commitments to its allies, because were the United States to lose or weaken those alliances, this would open the door to untold future revisionist aggression and upend the international order upon which U.S. prosperity and that of the United States’ most important international trading and security partners depends.
+ +Second, the United States has an incentive to deny Russia and China not just victory in general, but also victory through the use of nuclear weapons in particular. Rewarding their attempt at nuclear coercion would presumably lead to more aggressive employment of such approaches by Russia and China in the future, hence leading to more wars and greater risks of a full-scale nuclear exchange. Rewarding such coercion and aggression, moreover — and demonstrating the inability of U.S. alliance structures to deter them — would also encourage defensive nuclear proliferation to (and perhaps future offensive nuclear-facilitated coercion by) others as well.
+ +PRIORITIZING THEATERS
+ +A more difficult question is whether, in this scenario, the United States should prioritize one theater over the other. They present different military-operational situations, with the conflict against Russia being primarily a land war and that against China emphasizing naval power projection, although both would require significant air power. For this reason, each region is likely to draw most heavily upon somewhat different mixes of U.S. military capabilities and assets. It is conceivable, therefore, that the United States might not face unmanageably stark prioritization choices.
+ +Nevertheless, if the United States were forced to choose between concentrating upon Europe and concentrating upon the Indo-Pacific, Washington should prioritize the latter. Even if Russia succeeds in carving out for itself some kind of neo-tsarist imperium in Eastern Europe, Moscow lacks the economic, demographic, and material resources to hold it over the medium-to-long term, especially if confronted by strong and sophisticated adversaries. An allied loss in the Polish-Lithuanian theater in this scenario would be devastating, but even then, a sufficiently alarmed, angry, and resolute Europe could likely still — even alone — present Russia with just such a set of adversaries if it really wished to. Accordingly, the odds of the entire continent falling under the Kremlin’s sway — as well as the odds of Russia maintaining a new empire over the long term — seem low.
+ +By contrast, the implications of a Chinese victory in the Indo-Pacific seem more systemically problematic. Such a victory would very likely lead not merely to the bankruptcy of existing U.S. alliance guarantees, resulting in the Americans’ expulsion from the region — de facto, if not necessarily de jure (or at least not at first) — but also the creation of a Sinocentric imperium in East Asia. Nor would this new authoritarian Chinese regional order likely be particularly short lived. In contrast to the declining state of Russia, and despite some recent economic headwinds and the longer-term specter of demographic decline, China would not lack the manpower, military capabilities, or economic resources necessary to dominate its new network of tributary vassals. Between the two “theater-defeat” scenarios, therefore, from the perspective of the international order and the United States’ future role therein, an Indo-Pacific loss is probably the more traumatic and irreversible.
+ +Nevertheless, in saying that the United States should, in extremis, prioritize the Indo-Pacific theater, this paper is not suggesting that the United States should abandon efforts to protect its European allies in the Russia scenario. Prioritizing one thing need not mean euthanizing the other. Indeed, any failure to stand by NATO would likely have significant adverse consequences in the Indo-Pacific, whose leaders would be watching the war in Europe carefully as a window into their own ability to rely upon the United States when things become difficult. Just as the United States prioritized defending Europe from the Nazis in World War II without backing off in the war against Japan in the Pacific, even if the United States must now prioritize East Asia in certain ways, it should not abandon Europe.
+ +WHAT COUNTS AS “WINNING”?
+ +As the great power committed to maintaining the existing system of international order against revisionist challengers, and as the leading state in the two alliance systems challenged by opportunistic authoritarian aggression, the United States has a “theory of victory” requirement here of denying Russia and China the achievement of their own theories of victory. In Europe, for example, this means preserving Poland, Lithuania, and Ukraine as sovereign independent states, and as countries enjoying close security ties to the United States. In Asia, this means similarly preserving Taiwan’s autonomy and keeping the United States’ free democratic allies in Australia, Japan, South Korea, and the Philippines from having to become vassal states of the Middle Kingdom. As a status quo power facing revisionist aggression, the fundamental victory requirement for the United States here is thus simply that its adversaries do not “win.”
+ +To be sure, a broader and more satisfying sort of U.S. victory would see the threat of revisionist aggression from Moscow and Beijing recede (or end?) more broadly, rather than having those powers simply “put back in their place,” thereafter remaining as wounded and aggrieved states looking for future vengeance. Indeed, given the nature of the two authoritarian regimes in question, it is possible that the clear military defeat of either one could shatter its brittle internal legitimacy narrative and lead to regime collapse.
+ +That said, the United States should not assume that such regime collapse would end revisionist threats. After all, both polities have strong and vicious hyper-nationalist elements strongly committed to dark and semi-paranoid anti-Western discourse. Moreover, there is no guarantee that either Vladimir Putin or Xi Jinping would be replaced by rulers any less committed to violent international self-aggrandizement. Nevertheless, even if further revisionism could not be precluded by the replacement of the current government, the very fact of a decisive defeat could help reinforce future deterrence messages, especially to the degree that this defeat “felt” more like a consequence of the regime having overreached by striking out abroad than like the fruits of a nefarious Western conspiracy to conquer or subvert the state.
+ +To be sure, after a Western victory in either theater, it might be difficult to tell whether deterrence had truly been “restored,” for each regime might react to such a setback with a policy of tactical retrenchment — that is, effectively accepting only a temporary armistice in order to buy time in which to reprovision, reequip, and prepare to resume hostilities on better terms. Yet deterrence is always provisional and conditional, as it is contingent upon the deterring party’s success in maintaining concrete capabilities (and a perceived willingness to use them) sufficient to persuade a would-be aggressor, each and every day, that “today is not the day.” In this sense, the belligerent powers are not the only ones with agency here. Even a mere armistice would also give the United States and its allies a chance to be better prepared for a potential resumption of hostilities, and hence better able to deter the aggressors. In the face of revisionist moves against the geopolitical status quo, an approach that defeats the aggressor’s initial thrust, returns all players to the territorial status quo ante, and buys time in which the United States can further shore up its alliances and prepare to counter any further attacks looks more like victory than loss.
+ +As suggested above, moreover, the aggressor’s prior defeat at U.S. hands might itself help to redress the longer-term deterrence problem rooted in adversary assumptions about Western sociopolitical weakness. Rather than being presumed to be a soft and fundamentally weak-willed adversary, the United States would thereafter be “the folks who thrashed you last time, even though you used nuclear weapons.” With a track record of martial success against twenty-first-century near-peer adversaries — and with no less capacity than before to actually use nuclear weapons against future aggression if this is needed — the United States would thus be better positioned to ensure future deterrence than it is now.
+ +QUESTIONS ABOUT U.S. CREDIBILITY
+ +In general, there are two levels of U.S. credibility about which U.S. allies have reason to be concerned in this scenario, with the second being of more significance than the first. The first level is whether the United States would be willing to risk a direct clash with a great power adversary, in any form, were it to move against its allies. Here the allies ought to have little doubt about U.S. credibility, for in this scenario the United States not only did respond to aggression against its allies by throwing its conventional forces into the fray against the aggressors, but also responded effectively enough that it led to dramatic setbacks for the aggressors.
+ +The second level of allied concern is whether U.S. nuclear extended deterrence will remain available in the event that an adversary uses nuclear weapons against it — that is, whether the United States would be willing to use nuclear weapons in such a conflict if needed. This is a game-theoretical challenge dating back to the early years of the Cold War, which materialized once the Soviets acquired a strategic nuclear arsenal to counterpose against the U.S. one, and it raises a question to which no truly definitive answer has ever been given. In a context in which adversary nuclear weapons hold major U.S. cities at risk, to what degree would a U.S. president really be willing to “lose New York to save Hamburg”? On this level, the present scenario confronts the United States with a clear challenge: how much risk of nuclear escalation against the U.S. homeland should the United States be willing to accept in responding to an aggressor’s use of nuclear weapons against its forces and allies in theaters thousands of miles away?
+ +This is a challenging question to which no a priori answer is likely possible, as much would depend upon the specific battlefield circumstances, the geopolitical and political contexts, and the personalities of the leaders in question. To judge from U.S. deterrence policy over many decades, however, the answer to the question is “definitely some.” Nonetheless, U.S. intestinal fortitude in this regard is presumably not infinite. The United States was clearly willing to accept considerable risk of escalation to a full-scale nuclear exchange in order to deter Soviet aggression against its allies in Europe during the Cold War. Yet the United States also seems to have recognized that there was an inherent degree of non-credibility in a promise, in effect, to destroy the world in order to “save” (for instance) Hamburg from the Red Army.
+ +In response to this problem, the United States and its allies developed three answers that went beyond relying exclusively upon potentially homeland-imperiling U.S. strategic brinkmanship: (a) the British and French invested in their own nuclear weapons programs; (b) the United States adopted a “nuclear-sharing” policy under which it would provide nuclear gravity bombs for delivery by key NATO allies in time of war (while preserving U.S. control of such devices in peacetime); and (c) the United States deployed a variety of theater- and shorter-range nuclear delivery systems that would give it more options to respond to aggression without the stark choice between surrender and jumping all the way up the escalation ladder to a strategic exchange. Together, these choices added considerable operational flexibility to the collective NATO nuclear tool kit, enhancing deterrence without making nuclear use so casually thinkable that the United States would be tempted to engage in it absent the gravest of provocations.
+ +Today, by contrast, only the first of the United States’ three Cold War–era responses (British and French weapons) really remains viable, though even then in a form considerably attenuated since Cold War days and not optimized for theater-type engagements of this sort in any event. The second response (NATO’s nuclear-sharing policy) has been allowed to atrophy into a fairly noncredible operational capability that would be difficult to employ in a full-scale conflict, is vulnerable to both nuclear and conventional preemption, and which (at least until sizeable numbers of dual-capable F-35 aircraft come online) would have difficulty surviving and ensuring mission-completion against serious air defenses.
+ +As for the third response, the United States no longer has any effective U.S. nuclear assets designed for, devoted to, and deployed for theater-level nuclear missions. It does have a low-yield option in the form of the W76-2 warhead, but that device rides on a strategic delivery system, the Trident D5 submarine-launched ballistic missile. The United States has no flexible, theater-range nuclear systems to array against the considerable Russian and Chinese arsenals of diverse and flexible theater-range systems. This makes it harder to reassure our allies that we really would be there (in a nuclear sense) for their “Hamburg” — as well as harder to convince (and hence deter) the would-be aggressor.
+ +This is the basic challenge of the second-level question of nuclear use. It is surely possible for nuclear weapons to be too “usable,” and overquick resort to such tools could be catastrophic. Yet it is also possible for nuclear weapons use to be too hard to contemplate, for to find it truly “unthinkable” would be to invite aggression that cannot be deterred or combatted by purely conventional means. Deterrence policy is thus about finding the “Goldilocks point” — or, more elegantly, the Aristotelean Mean — between these bad answers. In the present scenario, however, the United States would surely be more able both to deter and to respond to aggression if it had more theater-range options.
+ +Now that nuclear weapons have been used in this scenario, this second-level question of nuclear use moves to the forefront. Fortunately, the facts of the scenario so far do not quite precipitate the most challenging dilemma, so it matters less that the United States lacks the more flexible theater-range nuclear options it needs.
+ +Presumably, U.S. allies have no special interest in the United States using nuclear weapons per se: their interest lies in being defended against aggression by whatever means are necessary — not excluding nuclear weaponry, but not necessarily employing it either. Indeed, at various points over the years, some allies have expressed concern that the United States might perhaps be too quick to use such weapons, particularly where such employment in theater would occur on their soil. (Over NATO’s history, U.S. defense planners have struggled incessantly with simultaneous European demands that the United States (a) be entirely ready to wage a nuclear war on their behalf and (b) not be too eager to do so, especially not in Europe. The equilibrium point between these demands is not always easily found.) Most likely, however, U.S. allies’ primary concern here is quite singular. Their fear is only that the United States might fail to use nuclear weapons in circumstances in which there is no way to protect the allies’ own existential security interests other than by using nuclear weapons.
+ +Through this lens, a critical question is whether this scenario is “one of those cases.” And in this regard, the scenario could be said not yet to present such a need. So far, the conventional situation does not seem to be one in which vital U.S. or allied interests are threatened in ways that would require U.S. nuclear use. On the contrary, the United States and its allies seem to be prevailing without it. The primary, existential question from the perspective of allied second-level (nuclear) assurance, therefore, has arguably thus not yet been raised. After all, it would presumably do little harm to the United States’ reputation among its allies as an extended deterrence protector — and might even enhance its reputation for responsible nuclear statesmanship — if Washington were to decline to use nuclear weapons where it did not need to use them.
+ +Instead, the remaining question here is whether a U.S. or allied nuclear response might be needed to the Russian or Chinese nuclear attacks simply because they were nuclear attacks. To this question, under these facts, reasonable people may disagree. Some might argue in the affirmative — claiming, in effect, that we “need” to use nuclear weapons to protect the credibility, to ally and aggressor alike, of the “nuclear” aspect of extended deterrence even when the United States does not need to use nuclear weapons for any actual operational military purpose in a war it is already winning.
+ +This paper, however, contends that on the current facts of this scenario, the United States does not yet need to use nuclear weaponry. The extended deterrence the United States provides to its allies has never been an exclusively nuclear insurance policy against aggression. Instead, it has been an inclusively nuclear one. It combines all elements of available military power that are required to deter aggression and to defeat it should deterrence fail. That is, the United States has promised to defend its allies by whatever means are necessary, but it has not promised to use any specific form of military power unless that form is necessary. This is not some U.S. analogue to the mindless automaticity of the old Soviet (and now Russian) “Dead Hand” nuclear launch system. Rather, it is an ironclad promise to the United States’ best friends of effective defense — not of U.S. nuclear use per se and no matter what.
+ +In this author’s view, a fundamental allied loss of trust in the credibility of the U.S. alliance guarantee would therefore probably not arise unless and until either (a) battlefield circumstances changed in ways that presented an ally with the prospect of catastrophic defeat absent U.S. nuclear use, and the United States did not then use nuclear weapons, or (b) the United States reacted to Sino-Russian nuclear use by retreat or some other measure of capitulation. Otherwise, remaining unintimidated and continuing to prosecute a successful conventional campaign — “fighting through” the adversary’s nuclear use in theater, as it were — should represent an optimal answer from the perspective of U.S. allies.
+ +In this scenario, at least, it is possible that some allies would wish the United States to use nuclear weapons against Russia and/or China, while others surely would prefer that we did not. On the whole, however, it would likely be less costly to alliance solidarity for the United States to continue to win the conventional conflict fighting alongside its allies without using nuclear weapons than it would for the United States to use such weapons (especially on European soil) when it was not absolutely clear it needed to do so.
+ +ALLIED SECURITY CONCERNS
+ +The security concerns of U.S. allies in this scenario are fourfold, deriving from their situations as relatively militarily weak states close to a powerful revisionist great-power predator that is eager to carve out a more expansive sphere of influence or empire for itself in the world. First and most fundamentally, U.S. allies’ security concern is an existential one: they must avoid the loss of their autonomy and independence as sovereign peoples. Beyond this, and deriving from this core concern, U.S. allies have a second security interest in avoiding the loss of their ties to other countries able and willing to assist them in meeting such primary security needs. Most of all, this means preserving military ties to the United States, but it also entails preserving their more general ability to leverage bilateral relationships or collective security institutions to meet security needs.
+ +A third allied security concern is more prosaic, but still significant. Each ally has a security interest in keeping the military forces of its local great-power predator as far from its own borders as possible. Moreover, irrespective of immediate border threats, allies have a security interest in limiting that predator’s deployment of long-range fires, aviation assets, naval power-projection capabilities, and other military tools capable of threatening that ally’s forces, facilities, or critical infrastructure from afar.
+ +More indirectly, U.S. allies have a fourth security interest in avoiding deep entanglement in economic, natural resource–centered, technological, supply chain, financial, or other relationships of dependency with either of the two great-power predators involved in this scenario. Such relationships may, or may not, provide immediate benefits (e.g., inexpensive goods, cheap energy, or corporate profits), but such ties are strategically debilitating and inimical to maintaining the sovereign independence that is each ally’s first-order existential concern. Such relationships give leverage over that ally by allowing the other power to administer rewards and punishments in ways that reduce the ally’s autonomy, undermine its ability to maintain a credible deterrent against aggression, and weaken relationships with third parties that are important to preserving its core security interests. (The existence of such relationships also likely contributes to adversary assumptions underlying the deep sociopolitical failure of deterrence discussed earlier: a country mired in structural dependency upon an aggressor will probably be assumed less likely to fight it.)
+ +SIGNALING RESOLVE
+ +Once deterrence has failed — or more challengingly, failed doubly, as in this scenario where both aggression and nuclear weapons use have occurred — the United States will likely have passed the point at which policy pronouncements and deterrence-related consultations with its allies can, alone, signal sufficient resolve. At this point, what counts most are U.S. actions and how adversaries understand them.
+ +In this respect, perhaps the most important signal the United States could send is to not slow or alter its activities against aggressor forces in the two theaters, except when such steps may be needed to preserve ongoing operations in a potentially nuclear environment. To this end, all relevant U.S. (and NATO) conventional assets should be readied to operate in a radiological-nuclear combat environment as quickly as possible, with ground assets dispersing to widely scattered field dispositions and air assets moving to dispersal airfields. This could also include the issuance of detection and protective gear, medical countermeasures, and relevant decontamination equipment, as well as surging radiation-hazard first responder units and medical personnel forward.
+ +Dispersing conventional capabilities — not merely land and naval units near the zone of operations but also aircraft from vulnerable bases to a wider variety of auxiliary dispersed locations, including those dual-capable aircraft (DCA) that would be needed for nuclear attack missions (i.e., unilateral U.S. assets in East Asia and NATO nuclear-sharing aircraft in Europe) — would also demonstrate resolve, unity, and collective preparedness. U.S. nuclear weapon storage vaults at relevant European airfields should also be readied for potential operations, and any existing plans for weapon dispersal to additional airfields that do not involve actual DCA attack assets should be implemented. (Care should be taken, however, not to fly NATO DCAs en masse to weapon storage airfields or to fly DCA from such airfields, lest Russia mistake this for an attack in progress.) Every effort should be made to keep these precautions from slowing the pace of combat operations against the Russian forces, which should not stop, though some impact might be unavoidable. (The scenario gives us notably little detail about the operational implications of the Russian and Chinese nuclear strikes.)
+ +The signals sent by these efforts are intended, together, to demonstrate in concrete form that (i) NATO will not give up in the face of nuclear provocations and (ii) NATO is quite prepared for the possibility of escalation. Beyond the theaters in question, moreover, U.S. and allied leaders in both Europe and the Indo-Pacific should make clear their intention to isolate the aggressors’ economies as completely as possible from the global economy (e.g., impeding Chinese oil shipments through the Indian Ocean and the Strait of Malacca, and ending all Russian resource exports) for the duration of their wars of aggression. This may help create additional incentives for moderation.
+ +The alert level of U.S. strategic nuclear forces would also need to be elevated, with vulnerable bomber assets dispersing to auxiliary airfields, and with portions of the force perhaps even beginning rotating in-air readiness patrols (though not flying on headings that could be mistaken for attack trajectories either toward Russia or toward China). U.S. intercontinental ballistic missiles (ICBMs) would remain on ready-to-launch alert, with logistics support crews immediately providing extra supplies of diesel fuel to ICBM bases and individual silos to prepare them to sustain alert operations during a potentially prolonged crisis in which reliance upon local peacetime power grids might be precluded by sabotage or cyberattack.
+ +Meanwhile, serviceable in-port nuclear-powered ballistic missile submarines (SSBNs) — not only in the United States but also in Britain and France — should muster their crews and put to sea as quickly as possible. Emergency notice should also be given to operators of critical infrastructure facilities in the United States, Europe, and East Asia, encouraging or directing them to implement whatever protective protocols they might have to defend against Russian and/or Chinese cyberattacks, and to move to insulate their systems as much as possible from the internet (even at financial cost or loss in operational efficiency) and prepare themselves to implement emergency service restoration or reconstitution plans.
+ +THE CRITICAL IMPORTANCE OF MESSAGE
+ +While these preparatory steps are important in their own right, they are also critical to the U.S. messaging strategy. To understand the importance of getting U.S. strategic signaling right, it should be remembered that the Russian and Chinese nuclear attacks in this scenario were notably limited. They hit only things in theater that were of tactical operational relevance, for instance, striking only a very small number of targets despite both adversaries possessing a huge numerical advantage in theater delivery systems. Moreover, they refrained from hitting anything in the U.S. homeland or that was of arguable strategic importance to the United States. This suggests that U.S. adversaries are themselves carefully considering escalation risks, and that they do fear provoking a large-scale nuclear response. If they understand that their nuclear use has not intimidated the United States and that the United States is indeed comfortable with escalation despite their previous assumptions to the contrary — but that, at the same time, U.S. war aims are limited, being confined only to restoring the status quo ante — the United States may have a chance to restore deterrence.
+ +Accordingly, these concrete military moves would be accompanied by full-spectrum public messaging — including by the president directly — making three key points:
+ +First, the United States would make clear that these nuclear-preparatory steps are indeed underway and that Washington is demonstrating in concrete ways the United States’ ironclad commitment to protecting the sovereignty and independence of its military allies by whatever means necessary.
+Second, the United States would make equally clear that under the current circumstances, U.S. nuclear weapons use is not yet necessary. U.S. messaging would stress that, while Russia and China’s nuclear use was the result of tactical desperation as their wars of aggression began to falter, the United States itself faces no such desperate circumstances. On the contrary, despite the United States’ strong preference to avoid using nuclear weapons and its willingness to use them if its adversaries force it to, the United States is currently prevailing in the conventional fight and intends to continue with that winning approach for so long as its adversaries’ fixation upon aggression makes it necessary to resist them in order to protect the security and independence of free sovereign peoples. Washington would also make clear that it remains entirely prepared and ready to use nuclear weapons itself if Russia or China leave it no choice, and the United States would warn them not to test its resolve by using nuclear weapons a second time.
+Third, the United States would make explicit that its war aims in this conventional fight are quite limited. The United States do not seek to inflict a “strategic loss” or regime change upon either Russia or China, but rather merely stop their wars of aggression. If they stop that aggression, the United States would have no more need to fight them.
+TREATY VERSUS NON-TREATY PARTNERS
+ +Much of this above-mentioned activity would be aimed primarily at protecting and reassuring U.S. military allies, as they would undoubtedly be the United States’ highest priority. Moves that would reassure those treaty allies would likely have some impact in reassuring non-treaty partners as well, but this would be merely a secondary, rather than primary, benefit.
+ +U.S. MILITARY OPTIONS
+ +The foregoing pages have already made clear the optimal immediate U.S. military responses to the current scenario: the United States should continue winning the conventional fight without employing nuclear weapons itself, while posturing itself to be ready for nuclear use if adversary nuclear threats or other military circumstances require. The United States would retain the option to do more, of course, and — depending how things develop — might well indeed still need to do so in the face of further Russian or Chinese provocations (e.g., massive U.S. battlefield reverses or a second instance of adversary nuclear use). Absent such further need, however, discretion should remain the better part of valor.
+ +WHAT IF THEY USE NUCLEAR WEAPONS AGAIN?
+ +In the event that U.S. adversaries chose to use nuclear weapons a second time, the United States — as it will have signaled that it was ready to do — should be prepared to cross the nuclear threshold itself. At least initially, the key would be to find a type and level of U.S. nuclear response appropriate to the delicate task of (a) signaling undiminished resolve and of (b) not jumping so much further up the proverbial escalation ladder that things spiral out of control.
+ +In this regard, one possibility would be to have a deployed SSBN in the Atlantic and one in the Pacific launch Trident missiles with reduced-yield W76-2 nuclear warheads toward two targets. (If the United States had the capability to do this, and reasonable confidence that its adversaries could see and understand that this is what the United States was doing, these weapons should also be launched on depressed ballistic trajectories clearly incapable of hitting strategic targets deep in the adversaries’ homelands.) These four targets, two in Russia and two in China, would be chosen on the basis of being military locations consistent with legitimate targeting under the law of armed conflict (LOAC), and the destruction of which would have a real impact upon adversary military operations in each theater, but without inflicting massive civilian casualties and without directly posing what could be seen as an existential threat to either ruling regime. Choosing these targets would need to be done relatively quickly, and carefully, but there would be at least some time for careful selection, informed not only by military analysis but also careful assessment of adversary leadership psychology and domestic political dynamics.
+ +The point in these attacks would be affirmatively to cross the “nuclear threshold,” including by hitting targets in the adversaries’ homelands — not merely to raise the ante somewhat for purposes of coercive bargaining, but also because, as Willie Sutton might have put it, that is where the targets are, as well as because the United States would prefer not to set off nuclear weapons on its allies’ territory if it can avoid it — while yet doing so in ways that adversary observers would be less likely to mistake for any sort of strategic attack and that signaled U.S. continuing commitment to a great degree of restraint. The U.S. president should also announce these launches publicly, making clear that this is a carefully limited theater action responding directly to these adversaries’ nuclear use and demonstrating that the United States will neither yield to their intimidation nor be provoked into overreaction, and that U.S. commitment to protecting its military allies remains undimmed. (Afterward, moreover, U.S. officials would publicly present the rationale for choosing those targets and that means of attack, also making clear how this decision was consistent with longstanding LOAC principles of necessity, proportionality, distinction, and humanity.)
+ +THE RISKS
+ +This has already been covered, or at least implied, in the paragraphs above. The primary risk lies in the danger that the United States fails to find the optimal Goldilocks point between the extremes as it tries to simultaneously (a) persuade allies and adversaries alike of U.S. seriousness and martial resolution and (b) not signal so much readiness or eagerness for escalation that the adversary feels provoked into catastrophic preemptive moves. Secondary risks also exist, among them the possibility either that some ally “opts out” of the conflict for fear of escalatory consequences, or that it “opts in” with too much enthusiasm by unilaterally taking steps that end up provokingadversary escalation rather than deterring it.
+ +THE LOAC
+ +The United States has long made clear its belief that the LOAC does apply to the use of all forms of weaponry in wartime, including nuclear weapons. Washington has also made clear in recent years its intention to abide by those rules in the event of conflict, even nuclear conflict. Despite U.S. commitment to such legal constraints, however, LOAC principles — if properly understood as U.S. officials have indeed carefully outlined them, and as generations of operational lawyers in the U.S. armed services have been trained on them — should not be a significant impediment to sound U.S. or allied strategy in this scenario.
+ +There is no question that the use of nuclear weapons is not illegal under the LOAC when the very existence of a state is threatened — this being a formulation that the International Court of Justice (ICJ) accepted in its 1996 advisory opinion on the topic — and the present scenario of aggressor use of nuclear weapons against Poland and the Philippines would certainly seem to raise such concerns. Nor would the LOAC rule out U.S. or other allied nuclear use in defending an ally from such attack as a matter of course, as the right of self-defense recognized by Article 51 of the United Nations Charter does not preclude collective self-defense. The law would not permit simply any nuclear response, of course. Nevertheless, under such quasi-existential circumstances the logic of compelling “military necessity” should permit judicious nuclear counter-strikes — both to prevent allied defeat in a growing conventional conflict and to dissuade further (and potentially full-scale) nuclear escalation by the aggressor — even if such strikes entailed considerable civilian casualties.
+ +LOAC principles are thus unlikely to be an obstacle to a careful and prudent response to the current scenario, even if that response turned out to involve U.S. or allied use of nuclear weaponry. The LOAC would preclude using a U.S. nuclear weapon directly to target Russian or Chinese civilians, of course, and U.S. and allied commanders would need to take feasible precautions to limit civilian damage (e.g., being as precise in their targeting as is feasible under the circumstances and using weapons of yield no greater than needed to accomplish the military objective). Yet it is hard to imagine military circumstances in this scenario giving rise to any need to do more than what a clear-eyed analysis of necessity and proportionality would permit.
+ +To the degree that non-kinetic options might exist that could affect the ability of Russian or Chinese forces to operate effectively in the specific theater wars described in this scenario, such activity might well contribute usefully to prosecution of the conflict below the level of U.S. or allied nuclear escalation. This might include, for instance: pursuing cyber or electronic warfare (EW) degradation of air defense activity or battlefield command, control, and communications (C3) networks; jamming or spoofing of adversary positioning, navigation, and timing (PNT) communications for engaged combatants; launching cyberattacks on infrastructure or transportation capabilities that directly contribute to the fight in theater; or jamming or otherwise engaging space assets in connection specifically with their support to theater operations. If means were available to degrade adversary nuclear C3, but only in the context of theater operations such as the two nuclear attacks that already occurred, this would likely also be a useful contribution to the fight, helping make further regional strikes more difficult.
+ +At least initially, however, care should be taken to avoid non-kinetic measures that might be interpreted as having existential implications. This could include, for instance, attacks upon Russian or Chinese space assets that support strategically critical functions such as national nuclear C3, cyberattacks upon critical infrastructure not associated with the specific military theater of operations, or perhaps even — given the paranoid and potentially fragile nature of the regimes in question — the dramatic stepping up of Information Operations (IO) or public diplomacy messaging that could be interpreted as encouraging regime change in Moscow and Beijing.
+ +This scenario certainly presents challenging questions. For this author, however, the particular fact pattern of Russian and Chinese nuclear weapons use outlined in Project Atom 2024 does not have to drive the United States to nuclear use itself, at least not yet. The United States must continue to stand by its allies and ensure that they are defended against aggression, while denying the aggressors any advantage from their choice to cross the nuclear threshold. Nevertheless, since (and for so long as) the United States is winning both wars without using nuclear weaponry, it should continue to do so, while yet making it very clear that it is prepared to escalate to nuclear use — and indeed actually ensuring that it is thus prepared — if the aggressors leave the United States no choice. With the moderate war aims appropriate to a status quo power seeking to defeat aggression but not to remake the world in its image, the United States has the chance here to confound Sino-Russian aggression, rebuild a strong deterrent posture, prove to its allies that it indeed does stand with them when bullets start to fly, and demonstrate reassuringly temperate nuclear statesmanship, all at the same time.

The circumstances of nuclear use described in the proposed 2027 scenario are unprecedented. The notional attacks would not only break an 82-year taboo concerning nuclear use in warfare, but nuclear weapons have never been used in conflict against other nuclear-armed states. These novel circumstances combined with the high stakes for all parties involved present U.S. policymakers with significant challenges in determining how to respond. Ideally, Washington would lead a course of action that would illustrate U.S. resolve and credibility to its allies and partners, avoid nuclear escalation, and demonstrate that nuclear use does not result in attackers achieving their strategic goals.
+ +The analysis below argues that the primary U.S. objective, if the People’s Republic of China (PRC) and the Russian Federation (RF) use nuclear weapons in the context of conflicts over Ukraine and Taiwan, is to manage and prevent escalation up to a major nuclear exchange. Secondary — though still vitally important — objectives include maintaining alliance relationships, ending the conflicts on favorable terms, and ensuring that the international community does not perceive nuclear use as benefitting the attackers. The United States and its allies should take several actions, militarily and diplomatically, to prevent these conflicts in the first place, and failing this, be ready to address the first instance of nuclear use since World War II in a manner that does not lead to a broader nuclear war.
+ +The following section explores why deterrence failed and what the United States can do to prevent these deterrence failures, before presenting the U.S. strategic objectives in the scenario.
+ +WHY DID DETERRENCE FAIL?
+ +In the notional 2027 scenario, the initial failure of conventional deterrence is the most consequential failure. Both adversaries used nuclear weapons because they instigated imprudent conventional conflicts against U.S. allies and partners.
+ +The purpose of nuclear use in both theaters appears to be twofold: (1) demonstrating the high stakes with which the adversaries view the conflicts and (2) terminating the war by deterring the United States and its allies from continuing to fight due to Western fears of additional nuclear attacks.
+ +The best way to prevent these competitors from resorting to nuclear attacks is to ensure that a strong and credible U.S. deterrent posture — integrating nuclear and conventional capabilities — prevents both from initiating aggression against allies and partners in the first place. The United States and its allies could have taken several political and military steps to improve this posture prior to 2027 when the proposed nuclear attacks occur. A deterrence failure would likely result from an adversary questioning the U.S. political commitment to its allies and partners. It is thus helpful to review signals the United States has sent in recent years that were intended to strengthen credibility, but which may have been misinterpreted.
+ +The U.S. government, in June of 2024, began to publicly signal its military plan to aid Taiwan’s defense. Admiral Samuel Paparo, head of U.S. Indo-Pacific Command, described the “Hellscape” strategy for defending Taiwan to a Washington Post columnist. Paparo explained that the “U.S. military would deploy thousands of unmanned submarines, unmanned surface ships and aerial drones to flood the area and give Taiwanese, U.S. and partner forces time to mount a full response.” He continued, “I want to turn the Taiwan Strait into an unmanned hellscape using a number of classified capabilities.” International media sources reported on Paparo’s remarks widely, serving a deterrent function for the United States.
+ +Admiral Paparo, however, also warned that the U.S. industrial base would need to increase its production of drones and other capabilities to implement this plan. Along the same lines, in 2023, a retired U.S. general questioned whether the U.S. military would be ready to defend Taiwan. This skeptical public rhetoric and an inability to attain necessary levels of readiness — something the Chinese government would surely learn from intelligence gathering — could contribute to deterrence failure by creating doubt about both U.S. resolve and U.S. military readiness for such an operation.
+ +Politically, there are reasons for the PRC to doubt the United States’ commitment to defending Taiwan due to the U.S. policy of strategic ambiguity. The United States terminated its Mutual Defense Treaty with Taiwan (the Republic of China or ROC) in 1979 when it formally recognized the PRC. Since then, U.S. relations with Taiwan have been based on the 1979 Taiwan Relations Act. The act obligates the United States to provide Taiwan “with defense articles and defense services” to allow the island “to maintain a sufficient self-defense capability” and “to maintain the capacity of the United States to resist any resort to force or other forms of coercion that would jeopardize the security, or the social or economic system, of the people on Taiwan.” The act created a policy of strategic ambiguity regarding U.S. defense of Taiwan. Despite this policy, President Biden has spoken strongly of U.S. support for Taiwan’s defense on four separate occasions. Following these statements, White House officials emphasized that U.S. policy regarding Taiwan remained the same, presumably to avoid raising tensions with China. Making a “mistake” about U.S. support for Taiwan four different times likely has sent a strong signal of U.S. intentions to the PRC. It will be important to see how the next president speaks about Taiwan, as their words will send important messages to Chinese leadership about the U.S. defense of Taiwan. It is worth noting, however, regardless of presidential rhetoric, that as long as the policy of strategic ambiguity is in place, there is room for Chinese leaders to question the U.S. commitment to assisting Taiwan’s defense.
+ +Beyond uncertainty regarding Washington’s military and political pledges to Taiwan, any Chinese attacks on Taiwan could stem from an assumption by President Xi that the stakes are higher for the PRC than for the United States. With Taiwan just over eighty miles from mainland China and the PRC increasingly asserting its dominance in the East and South China Seas, it is unsurprising that Chinese leaders would assume that the island of Taiwan matters more to Beijing than to Washington. The assumption that the United States and its Pacific allies have lower stakes in the region could lead Xi to calculate, first, that he could get away with annexing Taiwan by force, and second, that nuclear use could stop the United States from continuing to defend Taiwan in a crisis if the annexation does not go as planned.
+ +Turning to the European theater, the deterrence failure dates to at least 2014, when the RF annexed Crimea. Based on the West’s limited response to that action, Putin determined that it was worth attempting to take the rest of Ukraine by force in 2022. He did not anticipate Ukraine’s ability to resist the invasion or the support Kyiv would receive from the West. As Ukraine was not a member of the alliance, NATO’s Article 5 commitment did not apply, but members of NATO responded to the attack with intelligence, supplies, and funding. The level of NATO unity surrounding Ukraine and the increases in defense spending among alliance members are intended to send a strong deterrent message to Putin regarding further aggression, but if Moscow were in a desperate gamble to split the alliance and to reduce the West’s support for Ukraine in a conventional conflict, then additional attacks could not be ruled out.
+ +Finally, while preventing the conventional attacks in the first place is key to preventing the subsequent instances of nuclear use, this scenario does involve nuclear deterrence failures. The adversaries likely hoped that crossing the nuclear threshold would compel the United States and its allies to stop fighting. They may have doubts about whether the United States would employ nuclear weapons in regional conflicts.
+ +WHAT CAN BE DONE TO AVOID THESE DETERRENCE FAILURES?
+ +The U.S. military must prioritize the acquisitions required for the Hellscape plan and for follow-on military action in the region. In addition, the United States needs to find a way to sell Taiwan the military hardware required to defend itself from a PRC attack. If the United States does not provide what Taiwan needs in a timely fashion, it signals a lack of political resolve on the part of the United States and undermines Taiwanese military readiness. As (or if) the United States takes these steps to increase U.S. and Taiwanese readiness between 2024 and 2027, U.S. military leaders should project greater public confidence than they have to date about their ability to aid Taiwan’s defense.
+ +Short of altering the U.S. policy of “strategic ambiguity” regarding Taiwan’s status, there are several ways the United States could message its resolve to maintain the status quo. First, more statements like those made by President Biden about his intention to defend Taiwan — even if they must be clarified after the fact — are better than saying nothing or being dismissive of the issue.
+ +Second, top U.S. leaders should make clear to all audiences that the United States has long been a Pacific power and will continue to be one into the future. U.S. stakes in the region are significant: the United States has several allies and partners in the Pacific, maintains key military bases in the region, and benefits from the substantial percentage of global trade transported through the region’s waters. The United States has demonstrated its commitment to the Pacific in recent years with AUKUS, the trilateral security pact with Australia and the United Kingdom, and the Quadrilateral Security Dialogue with Australia, India, and Japan. U.S. leaders should not concede that the PRC has more of a stake in the region, and particularly in Taiwan, than the United States.
+ +Third, U.S. leaders should reiterate several talking points regarding Taiwan, both domestically and to the broader international community, to highlight why the United States seeks to maintain the status quo. One set of messages should emphasize what could occur if Taiwan loses its autonomy and becomes part of the PRC. Taiwan is a liberal democracy and a fundamental economic partner to the West. In particular, Taiwan is the world’s foremost supplier of semiconductors and advanced semiconductors, which are necessary for cell phones, computers, cars, and military hardware. If Taiwan were to be swallowed up by its large communist neighbor, this vitally important industry would be under Chinese control. The United States could lose access to the advanced semiconductors necessary for its defense.
+ +Another set of messages should address the PRC’s unlawful claim to Taiwan. There is no history of the PRC controlling the island. The Taiwanese are a mix of indigenous and ethnic Chinese people, some of whom have lived on the island for centuries, well before the PRC existed as a nation-state. The PRC claiming that it has a right to this island is akin to modern colonialism. In sum, the United States and its allies must make clear that taking Taiwan by force is an illegal and illegitimate action.
+ +There are also several steps the United States could take to strengthen its relationship with the Philippines and deter a potential attack on the island nation. The United States could do more to emphasize the importance of its partnership with the Philippines by assisting President Ferdinand R. Marcos Jr. with his domestic and international priorities, countering the Chinese disinformation campaigns in the country, providing additional military assistance, and engaging in more joint military exercises in the region.
+ +Moving to the European theater, the RF’s initial attack on Ukraine in February 2022 appears to have been a strategic blunder as it created an enemy on its border, united NATO members against Russia, and caused many European nations to increase defense spending. If at some point in the future, the RF attacks Poland or another NATO member, then there must have been some change of circumstances that made Putin question NATO unity in the face of nuclear use on NATO soil. Alternately, a nuclear attack could be a desperate attempt to stop NATO from supporting Ukraine’s defense.
+ +Finally, Washington must signal its ability and willingness to employ nuclear weapons in these theaters, if necessary, to defend its allies. Signaling comes in a variety of forms, from guidance documents, presidential rhetoric, weapons movement, and exercises that employ these weapons. While the United States under the Biden administration has been wise to avoid the type of belligerent nuclear rhetoric coming from its Russian counterparts, future administrations can privately message their willingness to defend allies using all available options.
+ +WHAT DOES WINNING LOOK LIKE?
+ +The United States has several immediate and long-term strategic objectives in the proposed scenario. Before outlining those goals, it is worth emphasizing exactly what is at stake in this conflict. The PRC and RF crossing the nuclear threshold means that the world has come significantly closer to nuclear war, and with it, a nuclear exchange ending millions of lives, the loss of societies, and even the risk of human civilization on the planet. Any U.S. leader considering how to address this scenario must have that grave reality — however remote — in mind.
+ +The primary objective in this scenario is to prevent nuclear escalation, whereby the United States and either the PRC, the RF, or both engage in escalating tit-for-tat nuclear attacks that result in a large-scale exchange of nuclear weapons. This is the primary goal because such nuclear exchanges would destroy societies, lead to millions of deaths, and cause widespread environmental devastation. Even if that outcome appears unlikely from the limited notional scenario, the circumstances are so unprecedented and the possibility of large-scale nuclear exchange so dire that avoiding large-scale nuclear escalation must be considered the goal that supersedes all others.
+ +Secondary objectives include the following:
+ +Reestablishing the pre-conflict status quo with the PRC and Taiwan and returning Ukraine to its pre-2022 borders.
+Demonstrating U.S. credibility to its allies and partners. This is especially important in terms of nuclear nonproliferation goals. If allies no longer perceive Washington as a trusted security partner, they may consider developing their own indigenous nuclear weapons programs. For example, some leaders in the Republic of Korea (ROK) have called for the country to develop nuclear weapons, and a small number have done so in Japan as well. Polls of the ROK public have found that a majority supports an indigenous nuclear program. Polling of Eastern European publics also indicated support for indigenous nuclear programs in the weeks following the RF’s 2022 attack on Ukraine.
+Maintaining the Philippines as an ally in the Pacific, to include the use of its military bases.
+Maintaining freedom of movement for all states within the Pacific Ocean.
+Reestablishing the taboo against first nuclear use.
+The inability to achieve any of these important secondary goals means the loss of U.S. global leadership. U.S. allies and partners are key enablers in promoting favorable rules, norms, and institutions within the international system. The PRC and the RF, along with Belarus, Iran, and the Democratic People’s Republic of Korea (DPRK), are increasingly forming a bloc determined to undermine U.S. global influence. If the U.S. response to this conflict were to cause the perception that the United States is not a dependable ally or partner, it would be a strategic win for the so-called Axis of Upheaval.
+ +After the nuclear attacks on the territories of allies, other allies and partners will closely watch to see how Washington responds. U.S. leaders will need to address the immediate challenge of the attacks and the ongoing conflicts, while also considering how their actions affect alliance relationships in the immediate and longer term.
+ +WHAT ARE THE RISKS — INCLUDING THEIR LIKELIHOOD AND CONSEQUENCES — OF ALLIES QUESTIONING U.S. CREDIBILITY IN THE EVENT OF STRATEGIC DETERRENCE FAILURE?
+ +It is fair to assume that the publics and elites within allied nations will perceive the nuclear attacks by the PRC and RF as deterrence failures, but it is also important to note that both states used nuclear weapons in this notional scenario when they were losing conventional conflicts against the United States and its allies. Nuclear use stemmed from a place of adversary weakness and was meant to undermine U.S. resolve to keep fighting and to illustrate the high stakes of the conflict for the PRC and RF.
+ +Given Putin’s behavior over the past decade, it is possible, and perhaps even likely, that U.S. allies and partners will emphasize the RF’s taboo-breaking decision to conduct a nuclear attack more than they will blame the United States for the deterrence failure. For example, Putin already has defied several international rules and norms when it comes to respecting national sovereignty, upholding sanctions against proliferating nations, and using chemical weapons against perceived enemies of the state. Moreover, his strategic mistake in invading Ukraine in 2022 and his administration’s persistent nuclear saber-rattling since may result in NATO leaders questioning Putin’s rationality. The theory of nuclear deterrence relies on leaders behaving rationally, so can the United States be blamed for not deterring an actor who may not be rational?
+ +The PRC’s nuclear use presents a different and perhaps more complex challenge. The Philippines is not under the protection of U.S. extended nuclear deterrence per the 1951 Mutual Defense Treaty, and yet in a Pacific conflict, the nation would become a target as the United States operates out of its military bases. A potential nuclear attack on a Philippine military base would likely provoke public backlash toward the United States, especially among Filipinos aligned with the political faction of former president Rodrigo Duterte. Some Philippine leaders have already expressed concerns that U.S. military forces on their islands make them a potential target of a nuclear attack. Maintaining this partnership after an attack may be difficult without extending the U.S. nuclear umbrella.
+ +HOW CAN THE UNITED STATES SIGNAL RESOLVE TO ALLIES IN THE EVENT OF STRATEGIC DETERRENCE FAILURE? WHAT WILL BE ALLIES’ SECURITY CONCERNS IN THE EVENT OF STRATEGIC DETERRENCE FAILURE? WHAT ROLE MIGHT CERTAIN ALLIES AND PARTNERS PLAY IN A RESPONSE?
+ +The most important means of signaling resolve is for the United States to continue prosecuting the respective conflicts and to respond to the nuclear attacks. Continuing the fight means that military forces may have to operate in spite of, and even in, radiation-contaminated environments.
+ +In the hours after nuclear use, the focus in the White House will be learning as much as possible about the attacks and assessing its response. This will be a tense, high-stress period, but Washington will want to make allies aware of its plans. Ideally, NATO’s Nuclear Planning Group would have discussed responses to RF or PRC nuclear use well before the beginning of this hypothetical conflict in 2027. The public response to the Russian attack should be presented as a NATO response.
+ +A key aspect of demonstrating credible resolve is maintaining public support for U.S. responses to the attacks; reminding the U.S. public of the strategic importance of its alliances will be vital to this support. News of nuclear use on allies in the Indo-Pacific and Europe will shock the U.S. public; many could fear nuclear detonations would occur on U.S. territory. As a result, securing public support in the United States for military action in defense of allies and partners following the attacks may be challenging. NATO expanded in a period when most Americans no longer worried about European security or nuclear war; the public salience of the alliance and of U.S. alliance commitments is likely much lower than it was during the Cold War.
+ +Before any potential conflict — and frankly, right now — the U.S. government, especially the president, should aim to better educate the public about the history of U.S. alliance relationships and their benefits. When it comes to most public discussions of U.S. allies today, there is too much talk about free-riding and too little about how U.S. economic, security, and political interests benefit from maintaining strong relations with its 30-plus treaty allies. Existing research from political science suggests that the U.S. public is more likely to support military action on behalf of formal allies than nonformal allies (such as Taiwan), so public education about Taiwan is also important. Current scholarship also indicates that support for allies among the U.S. public is based on “elite cues,” so leaders need to be providing positive talking points about U.S. allies if they want to build public support for military action.
+ +Following the use of nuclear weapons in this scenario, allies will have several concerns. Any countries targeted or immediately impacted by the nuclear use will need immediate assistance addressing the medical emergencies caused by the nuclear detonation. Allies could also be fearful of follow-on attacks; they will expect the United States to respond strongly to protect them.
+ +Allies and partners have a significant role to play in the messaging following nuclear use. They must unite in loudly and publicly condemning the nuclear attacks and should do so repeatedly. They should communicate that using nuclear weapons in these scenarios was unacceptable and neither nation will gain from using these weapons. These messages are key to reestablishing the nuclear taboo following nuclear use.
+ +The most challenging question facing the U.S. president after nuclear use by the PRC and the RF is how to respond to the nuclear attacks. The following section offers options for a military response that aligns with the strategic goals discussed in the section on U.S. strategic priorities.
+ +WHAT WOULD BE THE PRESIDENT’S MILITARY OPTIONS IN THE EVENT OF STRATEGIC DETERRENCE FAILURE? WHICH OF THESE OPTIONS WOULD YOU RECOMMEND TO THE PRESIDENT?
+ +Following the Chinese and Russian nuclear attacks, the president will hear many arguments that they must respond with nuclear weapons to signal strength and resolve. Some advisors will argue that responding without nuclear weapons will lead the adversaries to counter with another round of nuclear use. Others will warn that adversaries will perceive a nuclear response as escalatory and set the world on a dangerous path of nuclear exchange.
+ +Recommendations for the U.S. response to this notional scenario are based on the following assumptions:
+ +Assumption 1: Leaders may be unable to control nuclear escalation. Responding to the initial nuclear attacks with a U.S. or NATO nuclear attack makes it more likely that the United States will find itself engaging in tit-for-tat nuclear exchanges than if it does not initially respond with nuclear weapons. Once this contest of nerves begins, it could be exceedingly difficult to stop. Even if both sides do not want to escalate, in the fog of war, circumstances may add escalation pressures. For example, misinterpretations about the goals of adversary nuclear attacks (such as regime change or undermining command and control centers) could lead to escalation.
+ +Alternatively, nuclear-armed states could face other types of accidents, mistakes, or misinterpretations that could lead to nuclear use. There are several historical examples of such mistakes. For instance, during the 1962 Cuban Missile Crisis, an errant U2 pilot, an accidentally inserted nuclear attack training tape, and even a black bear in Duluth, Minnesota, could have led to a nuclear war that neither side wanted. Additionally, leaders below the commander in chief could conduct unauthorized attacks that could lead to further escalation.
+ +Some may argue that the theater nuclear use is far from a strategic nuclear exchange and does not present a risk of all-out nuclear war. In this argument, there is a clear and meaningful line between theater (or tactical) nuclear weapons and strategic nuclear weapons. It assumes that leaders could use tactical weapons but remain “below” the strategic threshold. There is little evidence to know whether this is true, and it could be a very costly and dangerous assumption to make. This argument of a clear demarcation between tactical and strategic weapons also has the unintended consequences of reifying three categories of weapons: conventional weapons, theater nuclear weapons, and strategic nuclear weapons. Whether intentional or not, this argument leads to the appearance that theater nuclear weapons are acceptable and thus more usable. And while smaller nuclear weapons do less damage, the damage is still significant and indicates a violation of a long-standing taboo. Furthermore, it is not clear if other leaders share the same assumption that there is a clear divide between employing theater and strategic weapons.
+ +In sum, significant destruction could occur if both sides begin employing nuclear weapons. This is unprecedented territory, and no one can predict with certainty what will happen. The potential destruction caused by nuclear escalation poses too great of a risk to make the ex ante assumption that leaders can fully manage this risk.
+ +Assumption 2: Military responses that lead to public humiliation of Putin and Xi are not likely to lead to preferred U.S. objectives. Considering the few checks on their decisionmaking, their regional and global ambitions, and their obsessions with legacy, it worth considering how to minimize actions that serve to humiliate Xi and Putin. For this reason, the West should explore finding the right balance between responses that are conducted in the open and those that can be conducted with plausible deniability.
+ +Assumption 3: To be deterred from further escalation, Xi and Putin must be fearful of follow-on actions. If the United States does not respond strongly to the nuclear attack, it will confirm that Xi and Putin were correct that the United States has lower stakes in both regions relative to the PRC and RF. The responses to the attack must be costly in terms of destruction of adversary capabilities — though not necessarily with nuclear weapons — and indicate that more attacks could follow.
+ +Policy recommendation: Given the extreme danger of beginning a process of nuclear exchange with U.S. adversaries and the fact that the adversaries may use nuclear weapons again regardless of U.S. and allied action, it is prudent to retaliate with punishing nonnuclear responses that are both public and clandestine. The United States should conduct timely and precise conventional attacks on adversary military bases or installations to degrade their military capabilities. Targeting should not include command and control capabilities, which could be perceived as escalatory. Moreover, these attacks should be reported to the public. This strong conventional response signals both that nuclear use will be punished and that the United States does not need to resort to nuclear use to do considerable damage to the adversary’s military capabilities. At the same time, the U.S. should signal its readiness to conduct limited nuclear operations, if necessary, by moving dual-capable aircraft and submarines to the regions.
+ +The United States should accompany these conventional attacks with clear assurances both in public and private that the United States does not seek regime change in the PRC or the RF. While in general the United States would prefer fewer authoritarian governments, in this conflict scenario, making adversaries believe their lives and governments are at risk could lead to further nuclear escalation. As prospect theory informs us, those in the domain of losses — as China and Russia would be in this scenario — are willing to take great risks. The United States simply seeks a reversion to the pre-conflict status quo. If either foreign leader assesses that regime change is a goal of the West, the conflict could quickly escalate.
+ +In addition to these conventional attacks, the United States should consider clandestine operations employing special forces teams that would degrade adversary military capabilities. These attacks do not need to be as immediate as the conventional attacks, but they should surprise the adversaries in terms of the damage done. If there are novel capabilities not employed by the West previously, this would be a suitable time to use them. The goal of these nonpublic attacks is to degrade enemy capabilities and demonstrate U.S. capabilities to adversary leadership with the plausible deniability of secret operations. PRC and RF leaders will not be forced to discuss these attacks in public and thus the potential humiliation or backlash that could come from these attacks is less likely. In other words, these operations should do serious damage while allowing Putin and Xi to save face. Once these actions have taken place, the United States should offer off-ramps to the RF and the PRC, while also making clear that the United States will continue fighting and may have to resort to nuclear use.
+ +WHAT ARE THE RISKS ASSOCIATED WITH A MILITARY RESPONSE?
+ +The most significant immediate risk is nuclear escalation. Other risks include the PRC and RF retaliating against the U.S. homeland and allies by other means, including conventional, cyber, or space attacks. The risks of not responding, however, include a loss of U.S. credibility, a breakdown in the U.S. alliance system, and a further weakening of the rules-based global order. Moreover, perceptions of “successful” use of nuclear weapons could increase proliferation pressures around the world.
+ +In addition to military responses to nuclear use, there are several other means by which the United States and its allies can pursue the primary and secondary strategic goals discussed previously. The president, with allies, should take non-kinetic actions against the RF and PRC to punish the use of nuclear weapons and demonstrate the costly repercussions of nuclear use. These actions should be taken along with the military responses described above. Potential non-kinetic responses include the following:
+ +Financial punishments: The United States could utilize the tools of the global financial system to hurt the PRC and RF economies. These tools may have limited utility in 2027, however, as both countries have worked to limit, to the extent possible, their economic vulnerabilities. Additional use of these tools may be necessary, but they will further the decoupling of adversaries from the global economic system led by the United States.
+ +Cyberattacks: The United States should consider conducting cyberattacks on the adversaries that are initially limited and measured, but which signal the possibility of pursuing attacks with greater effect if the conflict continues. This action does risk a dangerous escalation of cyber conflict — also unprecedented to date — so these actions must be calibrated very carefully. Attacks should avoid military command and control capabilities or otherwise blinding the adversary in such a way that they misinterpret the attacks as being the prelude to a larger attack.
+ +Diplomatic statements: In the days and weeks following the nuclear attacks, U.S. and allied leaders should make strong statements to all audiences — foreign and domestic — about how the PRC and RF have broken a long-standing taboo in international relations. In addition, Washington should work with allies and all other like-minded states to write and publicize a unified statement of condemnation from leaders around the world (with as diverse a geographic grouping as possible). In addition, a UN General Assembly resolution, such as the one following Russia’s attack on Ukraine in 2022, would help send the message that the international community disapproves of the nuclear use. These condemnations may not affect RF and PRC actions in the immediate term, but the lack of global condemnation following the first nuclear use since World War II would undermine the nuclear taboo moving forward.
+ +In making public statements about the nuclear attacks, the United States and its allies must consider how other members of the international community will perceive nuclear use — namely, was it successful for the attackers? The most important message to convey will be that nuclear attacks do not allow states to succeed in territorial aggrandizement. The existing global nuclear order has dealt with many challenges to date, and this nuclear use would be a grave one, but there are indications that the order would be able to survive this challenge.
+ +It is worth emphasizing here that improving U.S. and allied relations with states within the Global South before this notional conflict in 2027 is paramount. Though the international community broadly supported the 2022 UN General Assembly resolution condemning Russia’s attack on Ukraine, there have been fewer governments that have unilaterally condemned the attack or Russia’s nuclear saber-rattling, even among members of the Treaty on the Prohibition of Nuclear Weapons, a treaty that explicitly bans nuclear threats.
+ +The notional 2027 scenario discussed in this paper would pose significant challenges to U.S. leadership in the immediate and longer term. At best, the 82-year-old nuclear taboo is broken but further nuclear escalation is prevented. The United States is able to end both conflicts on favorable terms that punish the adversary’s militaries for nuclear use. Taiwan remains an autonomous democracy with a strong economy. Allies and partners remain committed to their security arrangements with the United States. Competition between the United States and both powers continues, but the PRC and RF are chastened. The message is clear that the use of nuclear weapons is not a means of achieving geopolitical goals, and the norm against their use is maintained.
+ +The worst outcome is almost too horrible to imagine but must be contemplated: large nuclear exchanges that devastate massive swaths of nations on all sides of the conflict.
+ +Somewhere in the middle of these extremes, a large nuclear conflict is averted, but the use of nuclear weapons and the resulting fear of being targeted make allies and partners reconsider whether they want to be in a defensive alliance. In a world with fewer allies and partners, Washington would lose a great deal of influence to shape the norms and institutions that make up the global order. This outcome likely would hasten the end of any remaining notion of a U.S.-led global order.
+ +Because so much is at stake, the most significant takeaway from this analysis is the importance of trying to deter such conflict in the first place. As described above, there are several ways in which the United States can improve readiness and signal its resolve. Once nuclear weapons are used in war, one cannot predict how conflict will escalate. Because nuclear weapons present an existential threat to humanity, there is nothing more important than avoiding nuclear war.

U.S. presidents, their advisers, and military planners must take seriously the possibility of limited nuclear use by adversaries in a range of plausible future contingencies. Resorting to the first use of nuclear weapons may appear attractive to U.S. adversaries as a means of seeking undeniable military and political advantage while simultaneously communicating exceptional resolve, risk acceptance, and stakes. In this way, the detonation of one — or multiple — nuclear weapons with deliberately lower yields on strictly military targets in the course of a conventional war or an intense crisis could compel the president of the United States, in their capacity as commander-in-chief, to weigh several risky response options, none of which may be particularly optimal across the full set of U.S. national objectives as articulated in peacetime.
+ +As Thomas Schelling observed in 1961, reflecting contemporaneously on the Berlin crisis (1958–1961), intense crises between nuclear-armed adversaries are usefully conceived of as games of competitive risk-taking, where the military effects of nuclear use may be a secondary consideration to the resolve conveyed. “We should plan for a war of nerve, of demonstration, and of bargaining, not of tactical target destruction,” Schelling observed. He added that should the United States resort to the use of nuclear weapons against Soviet military targets over Berlin, “destroying the target is incidental to the message the detonation conveys to the Soviet leadership.” For Schelling, prevailing in the crisis over Berlin would require “impress[ing] the Soviet leadership with the risk of general war — a war that may occur whether we or they intend it or not.” Limited nuclear use — or limited nuclear war — thus was an option meant specifically to communicate to the Soviet Union that the United States would be willing to tolerate exceptionally high risks to achieve the political ends it sought at the time. Today, military planners contemplating limited nuclear use may believe that target choice is more than an incidental matter; however, impressing on the adversary the prospect of an uncontrollable lurch toward Armageddon will remain central to such a choice. Adversaries need not be irrational or deliberately seeking nuclear escalation to contemplate such actions; all it may take for limited nuclear use to be attractive is that adversary leaders see that step as being less bad than the alternatives, which may include conventional defeat.
+ +Schelling’s prescriptions, written in 1961, may appear somewhat uncontroversial to U.S. audiences familiar with the history of the Cold War and U.S. interests in central Europe in the 1960s. Yet it is not inconceivable that should Russia, China, or North Korea choose in the twenty-first century to rationally resort to limited, nuclear first-use, their calculations will rest on a similar logic. Just as a U.S. president might have resorted to a nuclear detonation to convey a greater stake in the fate of Berlin to the Soviet leadership in 1961, so too might Russian president Vladimir Putin, Chinese leader Xi Jinping, or North Korean leader Kim Jong Un seek to “impress” on a U.S. president that running a risk of a general — possibly spasmodic — nuclear war over nuclear strikes on military targets is simply a risk not worth running. This logic underscoring the potential appeal of limited nuclear use is essentially deductive. To be sure, any nuclear use by U.S. adversaries would represent a world-altering event and the unambiguous manifestation of what U.S. deterrence planners consider “strategic deterrence failure,” but there remains a meaningful difference between successful war termination between nuclear-armed adversaries following limited nuclear use and war termination after a large-scale nuclear exchange. This difference may, quite literally, be measured in the millions-of-human-lives lost.
+ +The Project Atom study asks its authors to consider a particularly sobering scenario of limited nuclear use. U.S. adversaries — specifically, Russia and China — escalate to limited nuclear use in order to compel the United States to back away from continuing military action. In the scenario assigned to the authors, both Russia and China resort to nuclear first-use, paired with signals designed to convey their willingness to run greater risks than the United States. In the scenario, both Beijing and Moscow reference each other’s military actions, including the other’s nuclear strikes, and a strong collusive logic appears to drive each adversary’s willingness to run risks. While such a scenario may not cohere to how subject matter experts versed in the decisionmaking and bureaucratic idiosyncrasies of the Russian and Chinese political systems might conceive of pathways to limited nuclear use by those states, it represents something close to a worst-case scenario for strategic deterrence failure manifesting in near-simultaneous nuclear use by two near-peer U.S. adversaries in different theaters. Notably, the scenario also features a resort to nuclear use by both adversaries following exceptional U.S. and allied conventional successes: in Europe, the United States’ NATO allies successfully seize a substantial portion of Russia’s Kaliningrad Oblast and, in the Indo-Pacific, the United States successfully interdicts an amphibious invasion force destined for Taiwan.
+ +Given the problem described above and the prescribed scenario, this paper answers the query posed by the Project Atom study — namely, how the United States should respond to limited nuclear use — by centering the role of the U.S. president in nuclear decisionmaking. U.S. presidents, despite their limited briefings on U.S. nuclear capabilities and policies in peacetime, are unlikely to reason about matters of intra-war deterrence, escalation control, and war termination in a real crisis in the same manner that nuclear strategists writing about these matters in peacetime from their comfortable perches at research institutes might. Put simply, presidents are likely to be inordinately fearful of general nuclear war in the aftermath of limited nuclear use and averse to the possibility of even a single nuclear warhead detonating on U.S. territory. This may be the case even if presidential advisers and intelligence assessments do not necessarily ascribe a high probability to further nuclear escalation in the prescribed scenario. Given that the president is solely imbued with the authority to issue valid and legal orders to release nuclear weapons, any analysis of likely and plausible U.S. response options must center how current and future presidents may weigh response options. Despite however many options are in place or requirements provided in peacetime, a U.S. president cannot be compelled by their military advisers to seek any particular course of action in a given crisis. Given this, this paper largely argues that should Russia and China resort to partially collusive, deliberate, limited nuclear use in simultaneous crises, as specified in the Project Atom scenario, most plausible U.S. presidents — individuals who are overwhelmingly likely to be politicians, unversed in the finer points of nuclear strategy — will likely be compelled to stand down instead of engaging in competitive nuclear risk-taking. These men and women, whoever they may be, are overwhelmingly likely to find themselves worrying about the prospect of general nuclear war — or the “final failure” — as John F. Kennedy once did at the height of the Cuban Missile Crisis.
+ +If this is true, there is little doubt that several self-professed U.S. national objectives as articulated in peacetime would come under substantial stress, with potentially far-reaching consequences for U.S. grand strategy and foreign policy. This is ultimately the cost of strategic deterrence failure and why the United States must take the prospect of averting any nuclear use anywhere seriously. Other scenarios, including those featuring opportunistic limited nuclear use by one peer, may lead a president to accept greater risks, but this is outside of the scope of this study. As this essay will discuss, prudent planning for such failure can ensure that a U.S. president that may choose to avoid running the risk of nuclear escalation remains able to seek a world after strategic deterrence failure that is somewhat favorable for the United States. This can also be a world where the consequences of having resorted to limited nuclear use do not entail strategic victory for Russia and China, but rather a narrow, costly, pyrrhic victory.
+ +In reasoning about possible responses to strategic deterrence failure manifesting in limited nuclear use, U.S. leaders, advisers, and planners must be clear about the key national objectives and their relative levels of priority. In the event of strategic deterrence failure, the chief U.S. objective should be to ensure the avoidance of a general, unlimited nuclear war that could lead to fundamentally unacceptable levels of damage against the U.S. homeland as a result of adversary counterforce or countervalue strikes. Democratically elected U.S. presidents, charged by voters with defending the homeland, are likely to consider any nuclear attacks on U.S. territory as tantamount to unacceptable damage. Despite the somewhat methodical Cold War origins of this terminology, in the context of the given scenario, presidents are unlikely to be persuaded by their military advisers that the United States can ride out limited nuclear strikes and continue to exist as it did precrisis. This consideration presents an obvious and uncomfortable source of friction with U.S. assurances to allies as delivered in peacetime, a matter to which we will return later in this essay.
+ +Avoiding general kinetic damage against the homeland in the course of an ongoing war should thus be a key consideration for the president and should be prioritized above all other considerations, including, in the context of the scenario, supporting Taiwanese and Ukrainian objectives, supporting NATO and East Asian allies, and generally preserving the international order. These goals will remain operative but are fundamentally secondary to the survival and protection of the U.S. homeland. Because strategic deterrence failure of any magnitude is likely to be a world-altering event, it is quite likely that the precise circumstances of initial adversary nuclear use should cause a reassessment of key U.S. objectives. While the prescriptions that follow will make for unsettling reading in allied capitals, they should not be taken as a recommendation for the United States to exit the business of extended deterrence altogether. There are several plausible limited nuclear use scenarios that do not feature collusion as outlined in the Project Atom scenario where U.S. presidents may be substantially more willing to run risks in the defense of allies, but the scenario at hand here presents a particularly devilish predicament: the possibility of follow-on collusion by Moscow and Beijing in a general nuclear war against the United States.
+ +That said, strategic deterrence failure should not paralyze the United States in its ability to respond entirely. While restoring the territorial status quo ex ante in both Europe and the Indo-Pacific in the given scenario may not be possible at acceptable levels of cost to the United States, Washington should nevertheless seek to dissuade and deter further adversary nuclear use and terminate conflict on terms that would be deemed acceptable, if not entirely favorable. Critically, following strategic deterrence failure, U.S. adversaries will be correct in their assessment that their stakes — over Ukraine and Taiwan, respectively — are greater than those of the United States given the objectives articulated above. This is especially likely to be the case if Putin and Xi resorted to nuclear use out of desperation to preserve their political control and out of a belief that maintaining their territorial integrity requires running the risk of a nuclear exchange over these territories. Even if U.S. grand strategy and decades of investment in a global order that seeks to proscribe aggressive territorial revisionism may be at risk, many presidents may nevertheless opt for prudence in averting escalation.
+ +While the president’s advisers might point out that Russia and China, like the United States, would also be fearful of a general nuclear war — undoubtedly correctly — and that the U.S. nuclear force is survivable to the point of assuring their destruction should escalation prove uncontrollable, prudent presidential leadership would still have to consider the stepwise process of escalation after a U.S. nuclear response. As a result, the prioritization of the survival of the United States as a key national objective is likely to prompt such a prudent president to abstain from responses that could heighten the probability of a general nuclear war.
+ +Nevertheless, the president should be ready to employ the full array of tools from across the diplomacy-information-military-economics (DIME) spectrum to achieve the above-stated U.S. objectives as well as possible. Many of these steps can be planned for and conceived of well outside the immediate confines of a crisis, including the crises specified in the Project Atom scenario.
+ +Preventing adversary nuclear use and strategic deterrence failure will rest on manifesting in the mind of adversarial leaders the prospect of intolerable costs should they proceed, while simultaneously conveying that nuclear use is unlikely to confer tactical or strategic benefit. For both Putin and Xi, the most substantial cost likely relates to their personal political control over their respective states. While the United States should not unambiguously indicate that any nuclear use would lead to an end of their regimes, its declaratory signaling should maintain calculated ambiguity while conveying that catastrophic costs would ensue. While deterrence should prioritize a willingness to hold at risk what adversaries value most, threatening the personal political control or broader regime security of nuclear-armed great power adversaries is unlikely to advance U.S. interests — either in the scenario at hand or in general terms. Issuing such signals, by contrast, is likely to powerfully disabuse adversaries of any deliberate restraint that may still seem valuable after their limited nuclear use, rendering the prospect of follow-on uncontrollable escalation far more likely. In essence, such signaling by the United States would have the effect of further heightening the stakes for adversarial leaders to essentially existential levels concerning their personal political control. Successful war termination for the United States following limited nuclear use will require forbearance on such messaging. A practical problem for the United States, however, will be its noisy domestic political environment, where prominent political figures, including lawmakers from the president’s own party and the opposition, will likely issue calls for regime change or at least the removal of these leaders. U.S. adversaries will likely be unable to disentangle this “noise” from the “signal” of deliberate presidential messaging and assurances.
+ +At higher levels of escalation — particularly, follow-on strikes initiated by Russia and China — U.S. messaging could adopt the position that general nuclear war is a real possibility and would mean the effective end of Putin’s and Xi’s political control. The United States should simultaneously seek to maintain a robust set of flexible and responsive conventional capabilities, including capabilities forward-deployed to both Europe and the Indo-Pacific. It should also seek to enable its allies and partners in the regions to proffer similar capabilities while ensuring integrated military planning and operations with these allies. Critically, U.S. messaging in the course of a crisis prior to strategic deterrence failure should be contingent: emphasizing that consequences will befall adversaries should they choose to transgress the nuclear threshold, but that, by contrast, those same consequences will not befall adversaries should they choose to abstain from nuclear employment.
+ +It is useful to reflect on the factors inherent in the scenario that appear to precipitate a resort by both Russia and China to limited nuclear use. In the scenario, the most critical cause of strategic deterrence failure appears to be the result of two factors. First, leaders in both Russia and China, fearing conventional defeat and having experienced substantial conventional setbacks, are likely primed to reach into their nuclear holsters. Successful conventional denial, in other words, prompts these leaders to view nuclear weapons as a useful offset — for tactical, strategic, and psychological reasons. Second, both Putin and Xi appear to believe — probably correctly — that nuclear use will powerfully convey both their resolve and the substantial asymmetry in stakes that exists for them versus the United States.
+ +They may further believe that despite professed U.S. diplomatic and other assurances to allies in peacetime, a U.S. president in wartime may be deterred from employing disproportionate force, including through the use of nuclear weapons, if necessary, due to the prospect of uncontrollable escalation. Within the confines of the scenario, deterrence failure may have been averted through protracted conventional warfighting, even if this would entail substantial costs to the armed forces of the United States and its allies. Swift conventional success by the United States and its allies appears to have been a powerful motivator for both Russia and China to reach for their nuclear holsters. Deterrence failure in the scenario in no small part appears to be intertwined with both Putin and Xi fundamentally miscalculating the odds of conventional victory.
+ +In both the Indo-Pacific and Europe, the United States’ core objectives prior to strategic deterrence failure are to deter significant escalation, to preserve the territorial status quo, to reassure its allies, and to preserve the international norm against territorial conquest. Following strategic deterrence failure, no objective should be greater for the U.S. president than ensuring that the survival of the country is not threatened by the prospect of uncontrollable escalation into a general nuclear war.
+ +Victory for the United States within the presented scenario is far from straightforward despite the formidable conventional successes of allied forces in Europe and U.S. forces in the Indo-Pacific. A president and their expert advisers may disagree on the precise contours of victory in a crisis like the one envisaged in the scenario — just as President Kennedy and many of the key ExComm members (with the exception of George Ball) disagreed about the advisability of the Jupiter deal in the final days of the Cuban Missile Crisis. After strategic deterrence failure, a president may be rendered exceptionally sober by the prospect of general nuclear war — what Kennedy called the “final failure” — and be willing to take exceptional steps to seek prompt war termination, even on terms that would have been nominally unacceptable to that same president prior to adversary nuclear use.
+ +On the contrary, should a president choose to accept the risk of further nuclear escalation and retaliate in kind — either with nuclear weapons or a massive conventional attack — victory could amount to a decision by the adversary to seek termination of the conflict to avoid further damage to their nations or their political control. Because this latter option is far more contingent and depends on variables that may be fundamentally unknowable in the midst of a crisis (such as Putin’s and Xi’s proximal risk acceptance), it bears substantially greater risks. Should the U.S. president seek to sue for war termination following adversary nuclear use, there likely would be severe, unprecedented, and — from the vantage point of peacetime — intolerable consequences to how the United States’ capability to project power globally, to reassure allies at a distance, and to hold global leadership would be perceived. In such an event, the casualty would largely be the United States’ extended deterrence guarantees; a U.S. president would have palpably demonstrated that they are unwilling to run the risk of a nuclear war that could cause damage to the homeland to back its allies. But, in general, the United States would be able to maintain robust deterrence of adversaries for other scenarios, such as attacks on U.S. territory itself. The potentially fatal blow to the U.S. system of extended deterrence thus further underscores the severity of any strategic deterrence failure scenario involving limited nuclear use, but especially the collusive scenario articulated in Project Atom. As mentioned earlier, this analysis should not be taken as a repudiation of extended deterrence, but instead as an appraisal of the challenges to sustaining U.S. allied commitments in the aftermath of the precise limited nuclear use scenario at hand. Even if the course of action recommended here may heighten the probability of allied nuclear proliferation, this outcome — with its many uncertainties — may be preferable to inviting greater escalation by resorting to reciprocal nuclear attacks.
+ +The risks of allies questioning U.S. credibility in the event of strategic deterrence failure are substantial and likely insurmountable in the context of the scenario provided if Washington pursues a course of action that prioritizes its own national survival and immunity from nuclear attack. Allied leaders and a U.S. president will likely have a divergent sense of risk acceptance following strategic deterrence failure. For the presidents of the Philippines and Poland, in particular, nuclear use on their territories will be seen as a cataclysmic deterrence failure verging on an existential threat. For the United States, that same assessment would not hold, but the possibility of further damage in a general nuclear war would likely cause any prudent U.S. president to weigh the trade-off in supporting allies and averting damage to the homeland.
+ +There are likely conventional options that the president could adopt to inflict military costs on adversaries for nuclear use that would maintain an acceptable level of risk of follow-on nuclear escalation, but these may be insufficient for allied leaders and publics that could be motivated to see a U.S. nuclear response out of a desire for retributive damage against Russia and China. As a result, it is highly likely that following strategic deterrence failure, allied perceptions of the credibility of the United States would suffer drastically unless Washington opted for nuclear use in kind, which would present substantial risks and is unlikely to be preferable to the alternatives presented to most plausible presidents. As much as expert advisers to any president might profess support for U.S. alliances in peacetime, they might find that in the heart of a bona fide nuclear crisis, concerns about credibility are simply unpersuasive to a president concerned first and foremost with averting a pathway to nuclear war. This was precisely the predicament that arose in the final days of the Cuban Missile Crisis, when several ExComm members were opposed to Kennedy’s willingness to contemplate an off-ramp by way of withdrawing U.S. intermediate-range missiles deployed to Turkey, a NATO ally. Notably, adversary limited nuclear use against allies may be unlikely to prompt the same kind of national outrage and fervor that drove the United States to run risks in the aftermath of the Pearl Harbor (1941) and September 11 (2001) attacks on the homeland. The sole exception may be the Chinese strike specified in the scenario, which hits a U.S. naval base and presumably results in the deaths of thousands of U.S. servicemembers. This could encourage a president to accept greater risks in responding to China, though likely still well under the nuclear threshold.
+ +A president may further inquire how best to signal resolve to U.S. allies throughout the crisis. They may then be told that the most effective means of signaling resolve to allies would be to meet adversary nuclear use with some form of proportionate nuclear use. There are substantial risks to this, however. First, a proportionate response in the eyes of U.S. military planners may be interpreted as escalatory by the adversary and, therefore, potentially could prompt further escalation. Second, by employing nuclear weapons, the United States would concede substantial normative credibility that could be valuable in shaping global diplomatic narratives in a post-conflict environment (including with nonaligned states). The United States could aim to signal resolve to allies by inflicting calibrated, proportionate damage against adversary forces implicated in the nuclear strikes described in the scenario with its conventional forces. This is unlikely to sufficiently convey resolve as allies may not find a conventional response to nuclear use on their territory as satisfactory. While allies may not be uniform in this assessment of a conventional response, U.S. experts and officials, in consultations with allies, from East Asia to Europe, repeatedly contend with demands that nuclear use be met with nuclear retaliation.
+ +There are four basic categories of military response that could be considered in the course of the Project Atom scenario. First, a U.S. president could choose to forgo all military options and focus solely on war termination by diplomatic means. Second, a U.S. president could opt for a conventional response — either one designed to inflict tailored, proportionate damage, or one designed to disproportionately retaliate for nuclear use without employing nuclear weapons. Third, a U.S. president could opt for a nuclear response designed to inflict tailored, proportionate damage. Finally, a U.S. president could opt to seek escalation dominance and up the ante with significant nuclear use while communicating to the adversary U.S. resolve to escalate further should it be necessary to accomplish U.S. and allied objectives.
+ +Of these options, the first and second will hold the greatest practical appeal for any prudent U.S. president, who is unlikely to be versed in the strategic rationales for an in-kind or escalatory nuclear response and more concerned with preserving the safety, integrity, and survival of the United States itself. The first option may be unappealing, however, due to it appearing tantamount to complete strategic defeat. (Presidents may consider their own political legacies in weighing responses too.) Following strategic deterrence failure, there is likely an extremely low probability that the United States can, at acceptable levels of risk to the homeland, optimize for all its core strategic objectives, including reassuring its allies. As a result, a prescription for the president could be two-fold. First, they should opt for a limited conventional strike against the nonstrategic and regional nuclear force units involved in the strikes against Poland and the Philippines. At the same time, the president should employ a diplomatic strategy that seeks to persuade these allies as to the inadvisability of a nuclear response, which could beget further nuclear use against their territories (including against nonmilitary targets or military targets more proximal to population centers).
+ +While allies may be unpersuaded and motivated by a retributive logic demanding nuclear use, it is equally possible that internal fissures within allied governments and domestic political forces may support U.S. goals in persuading allies of the sufficiency of a conventional response. To deter further nuclear use by adversaries, the president should be willing to allude to intolerable and extreme consequences while underscoring to the broader world that the United States differentiates itself from Russia and China in viewing nuclear weapons as tools of last resort for truly extreme circumstances — not as a mere offset to the possibility of conventional defeat, as Moscow and Beijing have demonstrated in the scenario.
+ +Critics may counter that Russia and China resorted to nuclear use precisely because of U.S. and allied conventional military successes — and so why should a conventional response deter further nuclear use? The answer to this question rests on the logic of nuclear use by both countries in the first place. If both leaders crossed the nuclear Rubicon out of a belief that a single instance of limited nuclear use would paralyze the United States into inaction, the willingness to continue conventional military operations would disabuse them of this notion. By “fighting through” nuclear use and continuing to inflict costs without relying on nuclear weapons, the United States would deny Moscow and Beijing the political benefits of their limited nuclear use. Should Russia and China seek to deprive the United States of this option, they may be forced to opt for additional nuclear strikes against U.S. and allied forces, significantly raising the prospects of a total war across two hemispheres alongside the prospect of general nuclear war with the United States. If Putin and Xi remain rational, they may see no benefit in upping the ante in this game of competitive risk-taking, and instead may seek to minimize their further losses while retaining political control.
+ +The reason for not recommending that the president seek a tailored nuclear response or adopt an escalation dominance mindset and seek to escalate with nuclear weapons is because both options present substantial drawbacks and an unacceptable level of risk of a general nuclear war that would be most ruinous to the United States. Even assuming a small probability of escalation by the adversary should be sobering for a president given the consequences that could ensue. In the case of a tailored nuclear response option, U.S. adversaries may fail to be deterred if they continue to believe that their stakes in resolving their short-term territorial conquests are greater than those of the United States. Putin and Xi would, in their own minds, likely be willing to believe this — especially if they see the stakes in the crises as having now grown to encompass their own political survivals and legacies. If this is the case, a tailored, proportionate U.S. nuclear response, even if correctly interpreted as proportionate by U.S. adversaries, may beget further adversary nuclear use. Neither Putin nor Xi may choose to escalate in the types of targets they choose to hold at risk — keeping retaliation confined to military targets — but could continue strikes on NATO and Philippine territory by focusing on military targets. The collusive logic that is at play in the scenario could also influence this decisionmaking as both Moscow and Beijing may understand that their continued choice to participate in a game of competitive nuclear risk-taking will force the United States to contend with the challenge of waging a general nuclear war simultaneously against both powers. Hewing to the damage-limiting principles that have guided U.S. nuclear strategy for decades simultaneously against Russia and China would be largely unfeasible, even if survivable U.S. systems could inflict massive damage in punishment against both aggressors. A collusive all-out nuclear attack by Russia and China against the United States with their surviving forces would still result in the practical end of U.S. civilization and society.
+ +An escalation dominance approach, meanwhile, would succeed in conveying U.S. resolve and likely persuade Xi and Putin that their assumptions about U.S. stakes in these conflicts may be incorrect. However, a substantial use of nuclear weapons by the United States against military targets in Russia and China runs a serious risk of generating concerns in both states about the possibility of their forces remaining intact and about the viability of their regimes themselves. Without robust means of communication with the national or senior military leadership of both countries, which cannot be taken for granted, the United States may be unable to assure Russia and China that its choice to opt for nuclear escalation was not the precursor to a massive, damage-limiting counterforce campaign or a broader war of regime change. Fear of either outcome will encourage both Putin and Xi to contemplate larger-scale nuclear use. Because U.S. and allied combined military posture in the Indo-Pacific and Europe will also consist in the scenario timeframe of precise, conventional munitions, adversaries will have to also account for the possibility of massive, supplemental, conventional counterforce strikes. This option, while appealing for what it might convey about U.S. credibility to adversaries and allies alike, generates the greatest possibility of massive adversary nuclear use, which would result in unacceptable damage to the U.S. homeland. It would not be advisable for a president to run these risks immediately; instead, they should seek to maximize U.S. goals through the nonnuclear means articulated above, at least initially.
+ +There is a meaningful difference between the preceding two options in terms of how they might prompt reactions from Russia and China. Russia, which is known to incorporate a degree of counterforce targeting itself, may be more willing than China to run greater risks by attempting to destroy U.S. nuclear forces preemptively. In the 2028 timeframe specified in the Project Atom scenario, China’s nuclear forces will remain quantitatively inferior to those of the United States, and Chinese leaders would likely be deterred by the prospect of assured U.S. retaliation. As a result, it is substantially more likely that, even if opting for escalation dominance, U.S.-China nuclear exchanges could take place across several steps before either side considers massive nuclear strikes against the other. Despite this, Chinese leaders may remain pathologically vulnerable to fears of a disarming U.S. counterforce strike; these fears could be compounded by 2028 with the deployment of additional missile defense and conventional long-range strike assets in the Indo-Pacific.
+ +Regardless of U.S. objectives, it will be in the interest of the United States to have adversaries remain less concerned about the possibility of a massive, damage-limiting first strike than about limited retaliation (either nuclear or conventional). Additionally, the United States should endeavor to avoid feeding adversary expectations that it seeks to end their political control or regimes. The key to successful war termination will differ with regard to both Russia and China. For China and Xi, inflicting substantial enough damage to the People’s Liberation Army’s conventional and amphibious landing forces to render seizing and controlling Taiwan unfeasible will confer bargaining leverage. With Russia, the United States and NATO may try to use seized territory in Kaliningrad to sue for war termination with Putin. If either Putin or Xi begin to exhibit particular psychological pathologies indicating irrational risk acceptance (which cannot be ruled out), these assumptions may not hold, and the United States may be forced to contemplate greater escalation than might otherwise be prudent. Given the impossibility of predicting irrational decisionmaking pathologies in a serious nuclear crisis, further elaboration on this point will not be provided, though it does bear consideration.
+ +U.S. planners must also consider the law of armed conflict. Adversaries will expect a U.S. nuclear or conventional response to adhere to publicly stated prewar principles, which include an emphasis on counterforce targeting and compliance with the law of armed conflict. This should rule out adversary expectations of countervalue strikes (deliberate attacks against major urban population centers and other nonmilitary targets). However, this will likely also heighten adversary fears about a possible damage-limiting strike against their nuclear forces, command and control, and other enabling capabilities. While the United States will be unable to disabuse adversaries of its long-stated interests in damage limitation, to the extent possible, any U.S. nuclear or substantial kinetic response should be accompanied by assurances that it does not seek to destroy adversary nuclear forces or sever adversary national leadership from key military functions. To this end, a response should be accompanied by public and private messaging (if feasible) designed to indicate tailored punishment against military units implicated in the execution of nuclear strikes. There is no reason the United States should deliberately seek to eschew the law of armed conflict in navigating responses to the scenario at hand.
+ +The president would have a wide array of non-kinetic options available in the event of strategic deterrence failure. Choices would include broad diplomatic messaging to allies, partners, and the nonaligned world aimed at obtaining unconditional condemnation of Russia and China for resorting to the first use of nuclear weapons in war in more than 80 years. The president could simultaneously marshal U.S. diplomatic resources to seek a broad, international coalition condemning both countries. It is likely that certain nonaligned states or states more aligned with Russia and China would opt to blame the United States for Russian and Chinese nuclear use, citing well-trodden narratives built up over years by Moscow and Beijing about U.S. alliances, military posture, and other factors. The United States should be ready to actively counter this, including by declassifying intelligence as much as possible to demonstrate that nuclear use was a result of desperation for both Putin and Xi. Given the severity of the scenario and the implications for U.S. interests, the president should be willing to authorize broad declassification that would serve these ends, even at the cost of possibly compromising sensitive sources and methods.
+ +Practically, the United States would likely also seek to enhance international economic sanctions, but the efficacy of these sanctions is likely to be limited; in anticipation of a decision to employ nuclear weapons, Putin and Xi would likely have expected such a response and have been undeterred by the prospect, as their limited nuclear use exhibits. Other non-kinetic options could include cyber operations against both Russia and China. These could be carried out for a range of objectives, including sowing a narrative within both countries that seeks to convey to the Russian and Chinese people the erratic character of their national leadership; seeking intelligence on likely follow-on military action following deterrence failure; and, finally, undermining Russian and Chinese military operations. Out of caution, the president should ensure that U.S. offensive cyber operations, to the extent feasible, do not affect Russian or Chinese assertive political control over their own nuclear — or broader military — forces. In general, cyber operations, if detected, could prove escalatory. The president should be particularly cautious about authorizing operations aimed at penetrating sensitive systems related to strategic situational awareness or command and control, which could raise the fears in both states about non-kinetic interference in their nuclear forces either as an end in itself or as a precursor to broader counterforce strikes.
+ +A chief purpose of U.S. non-kinetic efforts should be to maintain the normative higher ground, which will be valuable in a post-conflict environment with allies, partners, and nonaligned states alike. Even if allied governments view U.S. credibility as having taken a fatal hit following a decision to resort to a nonnuclear response, allied publics may be more readily persuaded by a U.S. choice to respond in a more limited fashion, particularly if Washington is able to make the case that opting for more escalatory responses would likely have resulted in nuclear strikes on their territories (and further nuclear strikes, in the case of Poland and the Philippines). For Russia and China, however, U.S. non-kinetic measures will largely be peripheral in shaping their cost-benefit calculations on further escalation.
+ +It should be acknowledged that from the vantage point of peacetime in 2024, the above-stated analysis does not make for particularly encouraging reading. One does not need to have read this assessment of the scenario and U.S. response options to conclude that the strategic deterrence scenario presented likely portends “defeat” for the United States. However, this defeat should be construed narrowly: the United States likely fails to compel Russia and China away from seeking their territorial revisionist goals at substantial cost, but ultimately survives as a nation and polity to restore and seek influence in a post-conflict world. Writing about potential nuclear crises demands an abundance of imagination, and U.S. policymakers and planners should be clear-eyed about the possibilities that would remain for the country in a post-strategic deterrence failure world.
+ +The centrality of presidential decisionmaking about nuclear crises represents both a strength and a weakness in the analysis above. It is a strength because it contends with the often-heard dictum that military plans “never survive first contact with the enemy” — partly because reality is complex and inherently unpredictable, but also because the ineffable idiosyncrasies of presidential decisionmaking can only become known under the psychological and emotional stress of a real crisis. However, the choice to center the president and presidential guidance also represents an analytical limitation in reasoning about U.S. responses to limited nuclear use because it is inherently impossible to account for the various personalities that may one day be asked to reason about matters of nuclear war.
+ +Finally, for U.S. allies, this scenario presents the crystallization of long-held anxieties about extended deterrence. Indeed, as much as U.S. policymakers may see peacetime assurance demands from allies as a leaky sieve, they are born of well-placed anxieties about extended deterrence failing under extreme circumstances. Allied fears in this regard are not entirely misplaced and there are indeed scenarios, at the worst-case end of the spectrum, involving collusion by the United States’ two great power, near-peer, nuclear-armed adversaries that will bend and possibly break assurances made in peacetime. The Project Atom scenario could be one such example. Analytically, however, this should not condemn extended deterrence to the status of a bluff. Instead, the United States and its allies should be ready to consult, plan, and game out various strategic deterrence failure scenarios to ensure that they can be averted in the first place. For instance, in the provided scenario, it appears that escalation to nuclear use by Russia in the European theater was driven by Polish and Lithuanian conventional operations into Kaliningrad without a central decision by NATO or broader consultations with the United States. Ensuring coordination and strategic synchronicity between the United States and its allies will be key to avoiding the worst in high-intensity conventional crises. Finally, beyond the working- and expert-level tracks, U.S. assurances must be supplemented by high-level political engagement with allies, underscoring in particular the special role of the president in U.S. nuclear decisionmaking.
+ +Above all, this analysis should also underscore the essential importance of averting strategic deterrence failure in the first place. The hard choices U.S. nuclear-armed adversaries could force upon the United States by resorting to limited nuclear use are ones no president should be asked to consider.

Though much is known about nuclear explosions — their physics, their mechanics, their effects — very little is known about their use as weapons of war. History provides analysts a single war in which nuclear weapons were detonated, and a small number of occasions in which decisionmakers are known to have seriously contemplated their use. This record is thin gruel upon which to make compelling inferences, or from which to draw solid conclusions.
+ +A paucity of empirical data, however, is not evidence that nuclear weapons cannot — or will never — be used again. Nor does it exempt civilian policymakers and military practitioners from the responsibility of preparing to make choices about nuclear employment.
+ +Policymakers confronting a situation in which they find it necessary to consider whether, when, which, and how many nuclear weapons to use will have to answer questions that are at once philosophical and practical, moral and material, urgent and permanent. If they are of stable temperament and rational inclination, then policymakers will seek methodical ways with which to weigh the value of nuclear restraint against that of nuclear action. Such approaches will produce clarity in defining strategic objectives and war aims, intellectual empathy for the adversary’s decision calculus, and creativity in the operational art of designing alternative military courses of action.
+ +Scenario analysis is one method for comparing the advantages and disadvantages of alternative courses of action and, for strategists and planners, serves the same purpose as practice does for teams in any discipline: it doesn’t make perfect, but it does make progress. Each phase of a scenario exercises the thought processes involved in aligning military operations with war aims, and war aims with strategic objectives, under conditions in which some variables that might affect the likelihood of success are foreseeable and controllable, and some are not. In this way, scenarios pull assumptions to the surface, inspect their implications, and then test courses of action for consistency of logic, fidelity to principle, and resiliency to changes in condition.
+ +Scenario analyses, however, are abstractions of reality accompanied by storytelling — theory, reasoning, and argumentation. This is especially true for nuclear scenarios. There is, therefore, special risk in attending too much to a scenario’s mechanics and not enough to the concepts and commitments it calls into question. If nuclear war does move from being a possibility to being a reality, whatever the specifics, there is no evading the fact that what policymakers will be deciding is which and how many humans will not survive, or if any will survive at all.
+ +The strategy developed here is premised on analysis of a two-theater, two-adversary, two intra-war nuclear launch scenario (referred to throughout as “the scenario”). Where information is not available — either because it does not exist or because it is not specified in the scenario — the strategy relies on a set of reasonable assumptions. Some assumptions are about the dynamics of nuclear war, because there hasn’t been one from which to draw historical evidence. Some are about decisionmaking in the United States, about which relatively much is known in general, but nothing at all in the context of a two-theater war that involves nuclear use. Other assumptions are made about the scenario’s adversaries, because little information about their respective decisionmaking processes is available in the scenario itself.
+ +There is no standard definition of what elevates nuclear use from being limited nuclear war to being general — “all-out” — nuclear war. In the 1960s, the U.S. government planned for its nuclear forces to be of a size and quality to be able to execute a retaliatory strike that would destroy “between 20 and 25 per cent of the enemy’s civilian population and between 50 and 75 per cent of his industrial capacity.” Applying this measure to the scenario means that general nuclear war would produce the immediate deaths of approximately 376–469 million people. A recent study by climate scientists calculates that if the belligerents in the scenario detonated sufficient warheads to achieve this mutual 25 percent casualty rate, then follow-on deaths from post-nuclear famine would reach approximately 2.5 billion people within two years.
+ +In the absence of any less arbitrary threshold, this strategy defines the lower bound of general nuclear war as the detonation by any one state of the number of nuclear weapons needed to produce a total yield sufficient to kill 25 percent of a belligerent’s population. Detonations that occur below that threshold constitute limited, not general, nuclear war. The strategy similarly assumes, based on the above, that general nuclear war in the scenario would destroy modern civilization and might even constitute a species-extinction event for much of biological life on earth, including humans. It assumes that governments would cease to function, and that there would be no meaning attached to the idea of nationhood, as individuals and collectives would instead be left to struggle to survive. In other words, the strategy assumes that the costs of general nuclear war are so extremely negative that they far exceed any benefits derived from the defeat and unconditional surrender of the adversary.
+ +The strategy also is built upon the recognition that there is no empirical basis upon which to make predictions about the dynamics of nuclear war. Specifically, once nuclear exchange has begun, there is no fact-based reason to presume that the likelihood of de-escalation, or of controlled escalation, is greater than the likelihood of unrestrained escalation. The strategy therefore assumes that all nuclear detonations have an unknown probability of creating an escalatory spiral, regardless of variation in their specific features — for example their type, location, yield, casualty rate, and so forth. Even relaxing this assumption and allowing the likelihood of escalation to general nuclear war to be low instead of unknown does not change the basic inequality. The magnitude of the costs of general nuclear war are so great that even very small probability estimates produce very large negative results — ones so destructive that they dwarf any possible positive results of victory.
+ +The strategy presented here assumes that U.S. policymakers are rational actors. This means they are sensitive to the costs, benefits, and probabilities of various courses of action and base their choice of action on estimates of expected value: the net positive or negative effect on U.S. interests produced by the outcome of each course of action, multiplied by that outcome’s probability of occurring. The strategy also assumes that U.S. decisionmakers assess that the extreme costs of general nuclear war exceed any potential benefits derived from the adversary’s total destruction, and that they are aware that the detonation of any nuclear weapon has the potential to result in an escalatory cycle that ultimately produces general nuclear war.
+ +Within the set of nonnuclear outcomes, the strategy assumes that policymakers consider the benefits of conventional victory to be greater than those of a negotiated settlement, and that both are greater than the benefits of total defeat. It also assumes policymakers judge the value of maximalist victory — the unconditional surrender of the adversary — and of a negotiated settlement to be greater than the costs of conventional war because, in the absence of this assumption, the incentive would be for the United States to withdraw.
+ +The expected values produced by these combinations of probabilities, costs, and benefits mean that U.S. policymakers will prefer all nonnuclear outcomes to all nuclear outcomes (Table 1).
+ +In the absence of information to the contrary, this strategy assumes that the scenario’s adversarial decisionmakers also are rational actors whose choices reflect their estimates of expected value. This assumption, however, does not require the adversaries to arrive at the same rank ordering of preferences over outcomes as the United States.
+ ++▲ Table 1: Assumed U.S. Preferences over Outcomes
+ +In general, preference hierarchies can be classified as one of two types. Type-1 actors estimate that the costs of general nuclear war exceed any benefits derived from the adversary’s total destruction, whether by nuclear or conventional means. A Type-1 actor will therefore prefer all nonuse outcomes to all nuclear-use outcomes.
+ +Type-2 actors do not consider the costs of general nuclear war to exceed any benefits derived from the adversary’s total destruction, whether by nuclear or conventional means. A Type-2 actor can therefore prefer one or more nuclear-use outcomes to one or more nonuse outcomes. One possibility in the scenario, for example, is that one or both of the adversaries assesses that the expected value of general nuclear war is equal to or greater than the expected value of a defeat that requires conceding their political objectives and surrendering (Table 2).
+ ++▲ Table 2: Example Rank Ordering of Rational Type-2 Adversary Preferences over Conflict Outcomes
+ +If either adversary is a Type-2 actor, and it concludes that the United States has maximalist war aims and estimates the probability of conventional loss to be high, then this preference ordering makes the Type-2 adversary more likely than a Type-1 adversary to initiate nuclear war, and very unlikely to exercise restraint in waging it. Other preference orderings are possible, though for all rank order profiles the key differentiator between adversary type is the relative value placed on nuclear-nonuse outcomes compared to nuclear-use outcomes.
+ +This strategy makes assumptions about the United States, as outlined above, that define it as a Type-1 actor. This classification might be incorrect. Even if it is correct at conflict initiation, policymaker views might change once war is underway; so long as decisionmaking is driven by humans, the decisions they make will be vulnerable to variations caused by the full range of human biases, frailties, emotions, and impulses. Nonetheless, the United States is assumed here to be a firmly Type-1 actor because this assumption is consistent with the scenario’s emphasis on seeking to deter, rather than to fight, nuclear war. The strategy does not make the same assumption about the adversaries and instead accepts the possibility that each might be either Type-1 or Type-2 — not for lack of hope that they are the former and not the latter, but rather to account for the uncertainty that they are.
+ +The assumed expected value calculations and resultant rank order establish preventing general nuclear war as the primary U.S. strategic objective. The secondary U.S. strategic objective is for there to be no additional nuclear detonation, of any type or yield, anywhere. This secondary objective is responsive to the horrific effects that all nuclear detonations have on humans, other animal species, and their habitats, and to the risk that additional nuclear launches might escalate to general nuclear war.
+ +In the scenario, the United States has joined wars in two theaters after adversarial attacks on allies and partners. U.S. political objectives and war aims in both regions are twofold: to demonstrate intolerance for wars of choice and to retain the sovereignty and autonomy of U.S. allies and partners. Because policymakers cannot eliminate the possibility that the adversaries are Type-2 actors, and because the primary U.S. strategic objective is to achieve a nonuse outcome, U.S. warfighting strategy must start from the premise that for all belligerents there is a set of possible, acceptable political outcomes short of maximalism that they can accept. Seeking such an outcome requires implementing a U.S. warfighting strategy that uses diplomatic, economic, and military measures to communicate that the United States does not seek regime change or societal collapse. The strategy must also demonstrate nuclear restraint by not engaging in tit-for-tat nuclear actions, including posture, alert, or deployment changes.
+ +U.S. political objectives need to be supported, and its warfighting operations aided, by local allies in both regions in the scenario. Alliance discipline in communicating limited war aims is essential; inconsistent and mixed messages will undermine the ability of the United States to credibly signal both nuclear restraint and its desire to reach a mutually acceptable, negotiated settlement.
+ +As adversary confusion and the likelihood of misperception of U.S. intent increase, so does the likelihood of adversary nuclear use regionally and, ultimately, the likelihood of escalation to general nuclear war. The United States cannot impose signaling consistency upon its allies and partners, but they should regularly be reminded that mixed messages increase the risks of adversary nuclear use and escalation.
+ +In the scenario, U.S. allies across and within the two theaters differ in their reasons for entering into conflict, in the type and extent of the material contributions they make, and in their respective war’s immediate effects on their interests. Some allies might be dissatisfied with non-maximalist U.S. political objectives and wish to press for the adversaries to surrender on allied terms. The United States should attempt to address this objection by reinforcing that the purpose of limiting possible actions (e.g., nuclear use or nonuse) is to protect the alliances’ shared interest in averting the least favorable conflict outcomes: concession to the adversaries’ maximalist demands, or an uncontrolled escalatory spiral that begins with nuclear detonations, perhaps on allied territories, and that ultimately leads to general nuclear war.
+ +Allies might also take the view that the unwillingness of the United States to make nuclear threats or to use nuclear weapons on their behalf undermines long-standing U.S. policies of extended deterrence, and therefore increases their risk of being a victim of a nuclear strike. This misperceives key features of the post-detonation environment. In the first instance, the United States’ nonuse strategic objectives render as equivalent the security interests of U.S. allies and of the United States itself — nonuse is definitionally an “extended” objective. In the second, an environment in which an adversary has used conventional and nuclear weapons to attack a U.S. ally is one in which U.S. extended nuclear deterrence — adversary inaction produced by the threat of nuclear consequence — has failed.
+ +The possible reasons for detonating a U.S. nuclear weapon thereafter are three: to punish the adversary; as an element of a strategy to try to reassure allies by demonstrating that the United States will use nuclear weapons on their behalf; or as one element of a strategy aimed at deterring adversaries from additional nuclear use. Policymakers cannot be confident that the likelihood of producing these effects is greater than the likelihood of producing an escalatory spiral ending in general nuclear war. Because the primary U.S. objective of this strategy is to prevent general nuclear war, this risk of escalation means that the United States cannot use a nuclear weapon to punish the adversary, to try to assure allies, or to try to establish U.S. credibility and, on that basis, implement a new strategy of deterrence. This does not mean that the United States is not committed to its allies and their vital national security interests during the war. It does mean, however, that the United States’ obligation to defend them is addressed by the ongoing conventional fight and the strategic U.S. objectives of preventing additional nuclear detonation and general nuclear war.
+ +Achieving a nuclear nonuse outcome is commonly discussed under the rubric of intra-war deterrence. In this scenario, deterrence is applicable because military defeat of the adversaries is not possible. No matter how powerful and effective U.S. diplomatic, political, economic, and military measures are, they cannot render the adversary (or adversaries) incapable of continuing to fight: their nuclear arsenals will remain available for use even under conditions of international isolation, economic collapse, and conventional military defeat.
+ +Strategies of deterrence seek to alter adversary perceptions of the likelihood and magnitude of the benefits of an action in relation to the likelihood and magnitude of its costs. This assumes the actor is sensitive to costs, and that it has principles, people, objects, or assets that it values and prefers not to lose.
+ +The logic of deterrence, however, does not capture the full set of possible motivations for an adversary’s nonuse of nuclear weapons. An actor might choose to exercise nuclear restraint for one or some combination of at least seven reasons (Table 3).
+ ++▲ Table 3: Possible Reasons for Adversary Nuclear Nonuse and its Applicability in the Near-Term, Two-Theater, Intra-War Nuclear Use Scenario
+ +Moral or ethical compunction and fear of technical failure can be considered if not impossible then at least highly unlikely to inhibit an actor from nuclear use in any conflict scenario in which that actor has already successfully detonated at least one nuclear weapon. In the scenario, it also is reasonable to assume that none of the belligerents is likely to assess that any one of them has the capability to mount a meaningfully protective defense against a concerted nuclear campaign. The United States therefore can seek to deter additional nuclear use through the threat of cost imposition — a strategy of conventional or nuclear deterrence — or it can seek to convince the adversaries to pursue a mutually acceptable, negotiated, political settlement.
+ +In the scenario, U.S. adversaries first used conventional war to achieve political aims despite the threat of substantial resistance, continued to fight despite a decreasing likelihood of prevailing, then escalated horizontally by attacking a U.S. defense treaty ally, and finally escalated again vertically through the detonation of a nuclear weapon. The scenario does not contain sufficient information to make any analytically sound inferences about how or why the initial U.S. warfighting strategy failed to deter the adversaries from nuclear use. This strategy therefore interprets these behaviors as indicating that the scenario adversaries are highly cost tolerant, a characteristic that decreases the likelihood that strategies of deterrence through threats of cost-imposition will be effective.
+ +The strategy assumes that in both theaters the initial U.S. conventional warfighting strategy was to impose conventional costs meaningful enough and substantial enough either to eliminate the adversary’s ability to continue to fight conventionally or to convince it to sue for peace — that is, to deter it from carrying on fighting. The scenario describes the war as ongoing, meaning that the United States has been unable to destroy the adversary’s conventional capabilities or to threaten the type and severity of costs that would convince it to abandon its war aims. Given that both adversaries detonated a nuclear weapon during the war, moreover, the conventional costs the United States imposed, and those it threatened, also were demonstrably not effective at deterring intra-war nuclear use.
+ +It is possible that the United States would eventually identify and be able to threaten conventional costs that could hurt the adversary sufficiently in a way it didn’t anticipate and thereby deter further nuclear use or persuade it to concede. Pursuing such a strategy of deterrence, however, is high in uncertainty and, therefore, also in risk. It is not possible to know prior to making the threat or imposing the consequence that it will have the desired effect. Each such attempt has some probability of resulting in escalation to further adversary nuclear use, and there is no way to know if that probability is high or low. Even if the quality of intelligence assessments and other information about the disposition and preference of the adversaries is quite high, such information cannot eliminate uncertainty about the adversary’s likely course of action.
+ +The effects produced by the threat of nuclear cost imposition in a strategy of intra-war deterrence are similarly uncertain. This approach risks cultivating the adversaries’ belief that they might be able to achieve their strategic or political objectives by engaging in nuclear brinkmanship and escalation.
+ +The risk of encouraging rather than deterring adversary nuclear use applies equally to threats to and attacks on the adversaries’ nuclear infrastructure, via conventional kinetic or cyber weapons, including on units or sites from which a tactical nuclear strike has been launched. Such an action would not only run the risk of initiating an escalatory spiral, but the possible colocation of tactical with strategic nuclear weapons also means that strikes meant as limited retaliations might be misconstrued as strategic first strikes intended to deplete the adversary’s second-strike capability. In this scenario such a perception would therefore be expected to increase the likelihood that an adversary would launch a nuclear weapon, and perhaps execute a massive attack, possibly against nuclear assets or civilian targets in the U.S. homeland.
+ +U.S. warfighting aims in each region therefore will be limited and focal. In both regions, U.S. warfighting strategy should use conventional forces to try to prevent either adversary from advancing the current lines of contact as described in the scenario, but not to advance the line of contact itself. All kinetic and cyber actions should target only adversary military units and assets. Attacks on the adversaries’ homelands should include only those military units and assets that have been directly engaged in conventional kinetic or confirmed cyber-warfighting activity, and all U.S. military actions should adhere to international humanitarian law. To the extent possible, the United States and allied forces should execute operational concepts that minimize the military utility of adversary tactical nuclear weapons.
+ +If an adversary does detonate another nuclear weapon anywhere, then the U.S. intra-war deterrence strategy has failed, and the president will have to assess current conditions and decide whether to continue to fight conventionally or to concede. The United States should not respond with its own use of a nuclear weapon in theater or elsewhere, given the possibility of escalation to general nuclear war. This is true even if the adversary launches one or more nuclear weapons against nuclear assets, industrial facilities, or civilian centers in the U.S. homeland. If the homeland strike is limited, the adversary still cannot be certain that the United States will not use its nuclear weapons in the future and therefore might still be deterred. The president would therefore, again, have to assess current conditions and decide whether to continue to fight conventionally or to concede. If the homeland strike exceeds the lower bound of general nuclear war (an explosive yield that kills 25 percent of the U.S. population), then the United States, insofar as it exists, destroys much but gains nothing by sending a salvo in return.
+ +This strategy assumes that diplomatic and economic instruments — e.g., severe reprimands, changes in standing and status in international institutions, the imposition of economic sanctions, and other restrictions on adversaries’ abilities to participate in the global economy and to access the international financial system — were imposed as part of the initial U.S. warfighting effort. Given that both adversaries detonated a nuclear weapon during the war, the non-kinetic costs the United States imposed and those it threatened were not effective at deterring intra-war nuclear use. Even if the United States did not immediately implement the full retinue of available measures, the adversaries’ initial nuclear detonations suggest that threatening to impose more such costs is likely to have little persuasive effect.
+ +Non-kinetic responses should, nonetheless, continue to be elements of the ongoing U.S. warfighting strategy. They are useful insofar as they hinder the adversaries’ kinetic warfighting capacity, and the United States can use the possibility of relaxing these consequences in efforts to convince the adversaries that a mutually acceptable, negotiated, political settlement is possible.
+ +This strategy is based upon the rational calculation that, in this scenario, the overriding U.S. strategic objective must be to preserve a future in which humans can live in some form of society that permits more than the base struggle for near-term survival. It therefore confines the definition of war termination on favorable terms to those that govern the present moment, not those that might protect U.S. interests beyond it. There is no way to anticipate what U.S. interests after these wars will be, or what geopolitical structures might further them.
+ +The temptation when formulating alternative strategies based on nuclear war scenarios like the one considered here is to recommend courses of action that include U.S. nuclear use on the basis that there is some chance that it will succeed in convincing the adversary to do what the United States wishes — to argue, that is, that it just might work. This is precisely the temptation that policymakers must resist. No attachment to any political ideology, nor any idea of nationhood, can justify knowingly endangering humankind. This must certainly be true for any political ideology or nation that purports to hold sacred the inalienable rights of all human beings. What could be more contrary to this commitment than risking nuclear holocaust for entire societies of people who had no direct authorship in the policies of their governments?
+ +The urge to destroy adversary governments in such a situation would no doubt be powerful, but it is intolerable under any circumstance to risk the extinction of the human species in order to do so. Nuclear decisionmaking cannot be driven by pride or vengeance, or by the fear that, if the worst comes and the United States perishes, then so too do the values and principles that produced it. Nuclear decisionmaking must instead be guided by the conviction that liberal thought will reemerge, and by the imperative of preserving a world in which that is possible.
+ +Analyzing U.S. Options for Responding to Adversary Limited Nuclear Use
+ +++ +Gregory Weaver
+
The decision to focus Project Atom 2024 on the issue of how the United States should respond to limited nuclear deterrence failure in a conflict with a peer nuclear adversary was both wise and timely. Wise because doing so helps address key gaps in U.S. strategy development. Timely because the rise of China as a second peer nuclear adversary, and the increasing strategic alignment of Russia and China, create a heightened risk of collaborative or opportunistic aggression in two theaters that requires the development of a strategy and associated enabling capabilities to address this problem.
+ +Most nongovernmental analyses of the problem of war with a nuclear-armed adversary focus, understandably, on how to deter the initiation of such a conflict or on deterring nuclear escalation in such a conflict. Successful deterrence avoids the much uglier problem of what to do if deterrence fails.
+ +Focusing on deterrence alone, however, fails to address the very difficult problem of how the United States and its allies and partners can protect their vital interests while avoiding uncontrolled escalation to large-scale nuclear war when the adversary has already escalated to the limited use of nuclear weapons. Focusing on deterrence alone fails to address the complex task of thinking through the military and non-kinetic response options the United States and its allies and partners might require to achieve their objectives while avoiding uncontrolled escalation. Moreover, by failing to identify the range of response options required, perhaps through multiple instances of limited nuclear weapons employment by both sides, such deterrence-focused analysis also risks failing to identify the capabilities required to provide such options credibly and effectively. Finally, the process of thinking through how to address limited nuclear deterrence failure somewhat counterintuitively provides important insights into how to enhance deterrence of both war and limited nuclear escalation in war that an analytic focus on deterrence alone is unlikely to provide.
+ +Analysis of how to respond to limited nuclear deterrence failure is inherently scenario dependent for a number of reasons. The stakes of the two sides in a conflict have a significant impact on the war aims of the combatants and on their willingness to escalate and counter-escalate in pursuit of those aims. The political circumstances, particularly regarding issues of alliance cohesion and the internal politics of the combatants, also shape the options of both sides. The military circumstances are of course a critical factor in shaping the two sides’ strategic and operational objectives and the military means available to pursue them. Analyses must address a range of questions, including: Who is winning or losing, and why and how? Is one side asymmetrically vulnerable to limited nuclear escalation? Could horizontal escalation alter the military situation to one side’s advantage? Does one side have an endurance advantage in an extended conflict?
+ +Of course, were the United States to find itself engaged either in a conflict with one nuclear peer while seeking to deter opportunistic aggression by the other, or in simultaneous conflicts with both Russia and China, the interaction of these scenario-specific factors would be far more complex to assess and far more challenging to address.
+ +Project Atom 2024 asked its participants to conduct their analyses in the context of a single 2027 scenario involving two regional conflicts with Russia and China simultaneously. Thus, this paper addresses only that scenario, providing analysis of the four key issue areas identified by the project’s designers:
+ +U.S. Strategic Objectives If Strategic Deterrence Fails
+Assuring Allies after Strategic Deterrence Failure
+Military Response Options after Strategic Deterrence Failure
+Non-Kinetic Response Options after Strategic Deterrence Failure
+As the reader will see, this two-conflict scenario presents U.S. strategists with a complex set of issues. However, a more comprehensive analysis of the overarching two nuclear-armed adversary problem would require asking these same questions across a set of plausible scenarios that span the range of key strategic circumstances the United States might face. Examples of other scenarios that should be examined using the Project Atom 2024 methodology include:
+ +Conflict with Russia while deterring Chinese opportunistic aggression
+Conflict with China while deterring Russian opportunistic aggression
+Conflict with Russia and China in which the United States is winning conventionally in one theater and losing in the other when deterrence of limited nuclear use fails
+Conflict with Russia and China in which the United States is losing conventionally in both theaters when deterrence of limited nuclear use fails
+The full range of scenarios farther into the future when China is a nuclear peer
+There are bound to be additional important insights from analysis of these alternative scenarios that are needed to formulate a comprehensive U.S. strategy for this problem set.
+ +Project Atom 2024 posits a 2027 scenario in which the United States and its allies and partners face collaborative aggression by Russia and China in two theaters simultaneously. The scenario postulates that, despite collaborative Russian-Chinese aggression, U.S. and allied conventional forces far outperform Russian and Chinese conventional forces, almost immediately putting Russia and China in very difficult strategic circumstances 8–10 days after conflict initiation in both theaters. The scenario results in a dire strategic situation in which both Russia and China have initiated limited nuclear escalation, seemingly in response to losing the conventional conflicts they initiated.
+ +As noted earlier, U.S. objectives and potential response options in such a situation would be highly dependent on the specific political-military circumstances of a conflict. In the case of this scenario, however, several key facts regarding the strategic situation are unclear:
+ +Has the defeat of the Chinese landing force negated China’s ability to invade Taiwan, and for how long?
+How long will it take Polish forces to seize the city of Kaliningrad and the rest of Kaliningrad oblast?
+How much have Russian nuclear strikes damaged NATO’s ability to reinforce Poland and the Baltic states, and to seize Kaliningrad?
+How many Russian ground forces are where? Along the Baltic states’ borders? In Kaliningrad? In Belarus?
+Pointing out these uncertainties is not intended as a criticism of the scenario. But the fact that such details regarding the range of strategic circumstances the United States might face have such a significant effect on the analysis of the central problem does raise an issue for future analysis: How much understanding of the potential impacts of limited nuclear use on the course of a theater conflict between nuclear-armed adversaries is required to formulate an effective strategy for the potential range of such contingencies? It is likely that experts are reaching the end of what they can learn about this central question without detailed wargaming and simulation of twenty-first-century theater warfare that includes the limited use of nuclear weapons by one or both sides in the conflict.
+ +Project Atom 2024 is a first step in this direction, as it effectively examines the issues regarding what to do in the wake of limited nuclear deterrence failure by asking the right first-order questions at the unclassified level. But that is not enough. The Department of Defense needs to take up the challenge of a campaign of wargaming and simulation that will provide the necessary analytic basis for informed strategy development and military capability requirements identification.
+ +What follows is an analysis of the four key issue areas in the scenario provided.
+ +For the purposes of this analysis, it is assumed that the U.S. stake in both theater conflicts is sufficient for the United States to risk large-scale nuclear war. Whether either adversary perceives this to be true, however, is unclear. Stakes sufficient to take this risk clearly involve vital national security interests. The United States has historically perceived the sovereignty and security of its NATO allies as meeting this test. The purposeful ambiguity regarding whether the United States would intervene to defend Taiwan against Chinese military aggression makes it less certain that Taiwanese security meets this threshold, though the impact of the forcible incorporation of Taiwan into the People’s Republic of China on U.S. economic interests and U.S. alliances in Asia could well rise to a vital national interest.
+ +Before identifying potential U.S. strategic objectives in this scenario, it is useful to consider for a moment why deterrence of limited nuclear use failed in both theaters and whether there was something that the United States could have done to enhance deterrence of such nuclear use. While the scenario does not provide sufficient information to determine the answers to these questions with much confidence, it does at least hint at Russian and Chinese motivations for crossing the nuclear threshold.
+ +In both theaters, the adversaries’ unexpectedly poor conventional military performance puts them in fairly dire strategic circumstances very early in the conflict. In Europe, the combined effect of Russia’s failure to make any significant inroads into the Baltic states while simultaneously failing to stop the NATO offensive into Kaliningrad and eliciting direct NATO military intervention in Ukraine could hardly be worse. In Asia, the destruction of China’s invasion fleet before it can reach Taiwan denies the Chinese leadership their primary objective and is followed by internal unrest in opposition to the war. Limited nuclear escalation in both theaters offers some prospect of terminating the conflicts on terms Russia and China can accept, but the scenario does not describe Russian or Chinese intent. Neither adversary pairs their limited nuclear escalation with clear coercive political-military demands, making the purpose of their escalation unclear.
+ +It is tempting to say that the United States failed to clearly and credibly communicate its stake in defending its allies and partners in both theaters. However, it is also possible that the Russian and Chinese leaderships miscalculated not about U.S. will to intervene but rather regarding the ability of Russian and Chinese conventional forces to achieve their objectives even in the face of U.S. intervention if they both attacked at roughly the same time.
+ +There are four U.S. strategic objectives that should be pursued in both theater conflicts.
+ +The first is to restore or maintain the territorial status quo ante. This means that no NATO or Taiwanese territory remains under Russian or Chinese control (respectively) at the end of the conflict. This constitutes a fundamental denial of Russia and Chinese strategic objectives.
+ +The second U.S. strategic objective should be to restore deterrence of further nuclear use by Russia or China. Doing so would enable the United States and its allies and partners to continue to pursue the first strategic objective at lower risk and with a lower level of violence.
+ +The third U.S. strategic objective in both conflicts should be to avoid uncontrolled nuclear escalation. This means deterring large-scale nuclear escalation by Russia and China even if restoring deterrence of further limited nuclear use is unachievable.
+ +The fourth U.S. strategic objective should be to demonstrate that the adversaries’ limited nuclear escalation did not result in any meaningful political-military gains. Achieving this objective in one theater could enhance the achievement of the U.S. objectives mentioned above in the second theater. It would also arguably enhance deterrence of future aggression and escalation.
+ +The scenario’s description of the Ukraine conflict complicates the establishment of further clear U.S. strategic objectives consistent with the four above objectives. The scenario posits that some eastern NATO allies have begun deploying forces into Ukraine, and NATO airpower is now flying support missions for Ukrainian forces on the offensive in preparation for the liberation of Crimea “within weeks.”
+ +It is not clear, however, what U.S. territorial objectives should be in the Ukraine conflict post Russian nuclear use. Combined NATO-Ukraine forces pressing to drive Russian forces from all Ukrainian territory might make restoring deterrence of Russian nuclear use significantly more difficult and could increase the risk of uncontrolled escalation. A less risky, but still ambitious, option would be to demand Russian withdrawal from all Ukrainian territory that Russia has seized since the February 2022 invasion in exchange for NATO withdrawal from the portions of Kaliningrad it now occupies. However, this would leave Russia in control of Crimea.
+ +Regardless of which U.S. objective is chosen regarding Ukraine, U.S. objectives should clearly include termination of all fighting between NATO/Ukraine and Russia, consistent with the achievement of the other U.S. strategic objectives identified above.
+ +What is the relative priority of this set of potential U.S. strategic objectives in this strategic context?
+ +Restoring the territorial status quo ante (with a possible modification regarding Ukraine) while avoiding uncontrolled escalation are undoubtedly the two most important objectives. Achieving these two objectives in both theaters would amount to “victory.” Immediately restoring deterrence of nuclear use is not necessary to “win” the conflicts, but doing so would reduce both the cost and the risk of doing so. Achieving the two most important objectives would also arguably result in achieving the fourth objective of denying U.S. adversaries any significant political-military gain through their nuclear escalation, thereby enhancing future deterrence of war and escalation in war.
+ +In the scenario, there is no clear indication of whether success in one theater is more important to the United States than in the other theater. However, one thing is clear: U.S. and allied successes in achieving their objectives in one theater would be likely to affect the decision calculus of the adversary in the other theater regarding further nuclear escalation.
+ +The second key issue noted by the Project Atom 2024 designers involves how the United States can assure its allies and partners in the wake of a failure to deter limited nuclear escalation by an adversary. This is indeed an important question, as one potential adversary motivation to escalate is to shatter U.S.-led alliance cohesion. Maintaining such cohesion is critically important to the achievement of the highest priority U.S. strategic objectives in both theaters. Thus, effectively assuring U.S. allies after strategic deterrence failure is in effect an enabler of the primary war aims of the United States should a nuclear-armed adversary choose to escalate.
+ +Assuring allies in the immediate aftermath of adversary nuclear use, particularly if they have been the target of such use, is more complex than assurance while deterring first use. Allies might be concerned the United States will not respond forcefully enough to either restore deterrence and/or continue to defend their vital interests for fear that the conflict might escalate out of control and put the U.S. homeland at risk. Conversely, allies might fear that the U.S. response to adversary nuclear escalation will elicit further adversary nuclear escalation in the theater, putting the allies at increased risk.
+ +Despite these legitimate concerns, allies and partners in both theaters have no credible alternatives to U.S. nuclear extended deterrence commitments. In NATO, the only non-U.S. nuclear weapons capabilities are French and British. Other NATO allies are unlikely to see those forces as credible alternatives to U.S. nuclear forces in the wake of limited nuclear deterrence failure given the vast superiority of Russian nuclear forces over those of the United Kingdom and France combined. In Asia, there are no existing alternatives to U.S. nuclear weapons capabilities whatsoever.
+ +If U.S. responses to initial Russian or Chinese escalation make clear that the United States is willing to engage in a competition in dire risk-taking, and that Russia and China must also fear potential uncontrolled escalation, allies are likely to be reassured in the near term. The greatest fear of allies who rely on U.S. extended nuclear deterrence is that in extremis the United States will be unwilling to risk strikes on the United States homeland to defend them. A decisive early demonstration that this fear is unfounded would bolster allies’ confidence and potentially convince U.S. adversaries that they had miscalculated about the U.S. stake in the conflict, as well as about U.S. political will to defend that stake resolutely.
+ +However, if the U.S. responses result in further Russian or Chinese nuclear use against U.S. allies and partners, allied confidence will likely go down. Once deterrence has failed — as evidenced by limited adversary nuclear use against U.S. allies or partners — allies will want to be reassured about our ability to defend them against such attacks, not just deter them.
+ +Decisions about how to respond to limited nuclear deterrence failure will be about how best to achieve U.S. (and allied) political-military objectives while avoiding uncontrolled escalation. If the United States succeeds in achieving its objectives while avoiding uncontrolled escalation, allies are likely to be assured. And those U.S. response decisions may need to be made too quickly to allow for extensive consultation if they are to be effective. For example, if an adversary escalates to limited nuclear use in an effort to coerce war termination on terms it can accept because it is decisively losing the conventional war, how long can we expect them to wait to see if their coercive use has had the desired effect before they decide to escalate further?
+ +The third key issue raised by the Project Atom 2024 designers involves the range of potential U.S. military responses to adversary limited nuclear escalation. The relevant range of such military options will be a direct function of the political-military objectives they are designed to achieve or support.
+ +A recap of the U.S. strategic objectives identified above allows one to identify sub-objectives and military options to achieve them:
+ +RESTORE OR MAINTAIN THE TERRITORIAL STATUS QUO ANTE
+ +Potential Sub-Objective: Restore U.S. or allied conventional superiority following limited adversary nuclear strikes on key U.S. or allied conventional forces.
+ +Potential Military Options: Depends on the exact nature of the military impact of adversary nuclear use and the adversary’s own vulnerability to U.S. response options. Analysis is required to understand the range of potential targets this objective and sub-objective might dictate and to determine whether currently planned military capabilities enable effective strikes on such targets on operationally relevant timelines.
+ +RESTORE DETERRENCE OF FURTHER NUCLEAR USE BY RUSSIA AND CHINA
+ +Potential Sub-Objective: Convince adversary that their nuclear escalation was a dire miscalculation regarding how the United States would respond and that further adversary escalation will fail to achieve their objectives while increasing the risk of uncontrolled escalation.
+ +Potential Military Options: Must exceed either the level of violence or the strategic impact that the adversary anticipated — likely difficult to know with confidence — in order to shake their confidence in their ability to gauge how the United States might respond to further escalation. There is a potential role here for the calculated revelation of capabilities of which the adversary was previously unaware that have potentially decisive military effects (“You didn’t tell me they could do that. What else don’t I know?”).
+ +AVOID UNCONTROLLED NUCLEAR ESCALATION
+ +Potential Sub-Objective: Convince adversary that U.S. nuclear responses and conventional operations are being conducted in pursuit of limited war aims that do not constitute an immediate threat to state survival and do not constitute the initiation of a large-scale counterforce attack designed to negate their strategic nuclear deterrent.
+ +Potential Military Options: Avoid strikes that threaten the adversary’s ability to detect nuclear attacks, command and control their nuclear forces, etc. Pair messaging about the purpose of the U.S. response with promises of U.S. restraint if Russia or China were to cease nuclear use.
+ +DEMONSTRATE ADVERSARY LIMITED NUCLEAR ESCALATION DID NOT RESULT IN MEANINGFUL POLITICAL-MILITARY GAINS
+ +Potential Sub-Objectives: Send a message to the adversary in the second theater of conflict that limited nuclear escalation is unlikely to have the coercive effects they seek. Send a message to future potential adversaries that there is no nuclear coercive offramp from failed conventional aggression against the United States and its allies.
+ +Potential Military Options: Almost all the options noted above could serve this purpose if effective in denying the adversary their objectives and in making clear that further nuclear escalation increases the risk of uncontrolled escalation. The nature and extent of U.S. and allied resolve must be messaged appropriately.
+ +TERMINATION OF FIGHTING BETWEEN NATO/UKRAINE AND RUSSIA, CONSISTENT WITH ACHIEVEMENT OF OTHER U.S. STRATEGIC OBJECTIVES
+ +Potential Sub-Objective: Create facts on the ground that provide negotiating leverage that enables termination of the Ukraine conflict.
+ +Potential Military Options: Seize more or all of Kaliningrad to use as a bargaining chip. Escalate level of NATO military intervention in Ukraine conflict.
+ +There are several key issues associated with the military response options outlined above that need to be taken into account.
+ +NUCLEAR OR NONNUCLEAR RESPONSE?
+ +The first of these is whether the U.S. military responses to Russian or Chinese nuclear use should be nuclear or nonnuclear. If the objective of the U.S. military response is to restore deterrence of nuclear use, then there are several problems with a nonnuclear response. First, if the purpose of the adversary’s escalation was to coerce war termination on terms they can accept because they are decisively losing the conventional war, then a nonnuclear response may convince them that they simply need to hit the United States harder in pursuit of their objective. Further, they may conclude that it safe to escalate because the United States is reluctant to respond in kind for fear of uncontrolled escalation. Second, if restoring deterrence requires that the United States respond in a more severe way than anticipated by the adversary in order to convince them that they cannot be confident in predicting future U.S. responses to further escalation, then a nonnuclear response is less likely to meet this criterion.
+ +If the U.S. objective is to restore U.S. or allied conventional superiority following limited adversary nuclear strikes, then the decision to respond with nuclear or nonnuclear weapons should hinge in part on which response is most likely to be more militarily effective. Increasing the range of relevant targets susceptible to a U.S. nuclear or nonnuclear response option would increase the range of options available to the president.
+ +Finally, for the U.S. objective of avoiding uncontrolled nuclear escalation, at first glance it might seem that nonnuclear military response options may be preferred. And in some circumstances this would be true. However, if the effect of selecting a nonnuclear response to adversary nuclear escalation is to convince the adversary that the United States is so concerned about uncontrolled escalation that it fears responding in kind, then a U.S. nonnuclear response could actually increase the risk of eventual uncontrolled escalation. This may seem counterintuitive, but if a U.S. nonnuclear response to adversary limited nuclear use results in encouraging further adversary nuclear escalation, then the U.S. nuclear responses that may eventually be required to achieve U.S. objectives are likely to be larger in scale and more provocative in their effects. This could well make uncontrolled escalation more likely.
+ +STRIKE RUSSIAN OR CHINESE TERRITORY WITH NUCLEAR WEAPONS?
+ +The second key issue regarding U.S. military responses to adversary limited nuclear use involves whether to strike targets on Russian or Chinese territory with nuclear weapons given the potentially escalatory nature of such action. On the one hand, strikes on the adversary’s homeland would cross a potential firebreak against uncontrolled escalation. On the other hand, making the adversary’s territory a sanctuary from U.S. limited nuclear responses could create a potentially decisive asymmetry in the ability of the two sides to achieve relevant military effects with nuclear weapons. A limited U.S. nuclear response (or a credibly communicated threat) that makes clear that Russian or Chinese territory will not be a sanctuary if the adversary continues to escalate could be effective in restoring deterrence following adversary first use. This decision in particular will be highly scenario dependent.
+ +RANGE OF AVAILABLE NUCLEAR OPTIONS
+ +The effectiveness of U.S. military response options in the wake of adversary limited nuclear escalation will in part be a function of the range of available nuclear options available to the U.S. president. Identifying future nuclear force and capability requirements first requires development of a future strategy for addressing the two-peer nuclear threat environment, a strategy that is likely to create new operational requirements for nuclear and conventional forces. But strategy development alone is not enough. Detailed wargaming and simulation is needed to analyze the ways in which limited nuclear use by both sides potentially affects the course of twenty-first-century conflict and escalation dynamics across a range of scenarios and strategic circumstances. Without such analysis, U.S. efforts to identify the range of nuclear options needed to address limited nuclear escalation will risk missing key insights.
+ +HOW TO MESSAGE U.S. INTENT AND WAR AIMS PAIRED WITH A GIVEN MILITARY RESPONSE
+ +As Thomas Schelling first made clear in his book Strategy of Conflict, there are certain strategic circumstances in which deterrence or the avoidance of further escalation can only be achieved if one pairs a credible threat of military response with a credible promise of restraint that provides the adversary with an acceptable, if not desirable, offramp. Given the clear role of coercive limited nuclear use in Russian strategy and doctrine, and the potential for China to adopt a similar strategy and practice when it soon acquires the necessary nuclear capabilities, the United States must determine how it will formulate and implement this pairing of threat with promise to deter such limited nuclear use. This includes not only ensuring that U.S. nuclear forces have the requisite range of capabilities to make the threat element credible and effective, but also determining what forms of restraint the United States is willing to promise and how to make such promises credible and effective in the context of a high-intensity theater conflict in which nuclear weapons have already been employed.
+ +RECOMMENDED MILITARY RESPONSE OPTIONS
+ +The final step in a scenario-based analysis of this central problem is making recommendations regarding U.S. military responses to Russian and Chinese nuclear escalation in this scenario.
+ +Regarding Russian escalation, the United States should simultaneously pursue its objectives of restoring the territorial status quo ante, reestablishing deterrence of further nuclear use, and restoring U.S. and allied conventional superiority following limited Russian nuclear strikes. This could be done by executing low-yield nuclear strikes on key military targets in Kaliningrad paired with clear messaging that Russia must halt further nuclear use and that U.S. war aims are limited to restoring the territorial status quo ante vis-à-vis NATO (and possibly a return to the pre-February 2022 borders in Ukraine). However, should Russia escalate with further nuclear use, U.S. war aims might change, and U.S. military responses will become more severe.
+ +Regarding China, assuming Chinese forces are no longer capable of conducting a Taiwan invasion due to U.S. and allied conventional actions, simultaneously pursuing the U.S. objectives of restoring deterrence and restoring U.S. and allied conventional superiority following limited Chinese nuclear strikes (as the territorial status quo ante already is intact) could be an appropriate course of action. This could take the form of a U.S. response in kind on three of the militarized islands in the South China Sea: Mischief Reef, Subi Reef, and Fiery Cross. Such strikes would not affect the Chinese mainland and, given the U.S. position on territorial disputes in the South China Sea, would not constitute attacks on Chinese territory. This response would make clear that the United States will neither tolerate, nor be disadvantaged by, Chinese limited nuclear use. These strikes should be paired with clear messaging that U.S. war aims are limited to defending Taiwan and our regional allies and to achieving an immediate ceasefire. However, it should be kept in mind that should China escalate with further nuclear use, U.S. war aims might change and the Chinese mainland may not be a sanctuary.
+ +There is a wide array of potential non-kinetic response options to adversary limited nuclear use in this scenario that could further the achievement of the U.S. strategic objectives identified above. The most important of these are the following (in descending order):
+ +Messaging in support of achieving the purposes of U.S. military responses to adversary limited nuclear use. How this might be done has been discussed above. Formulating this kind of messaging should become part of both the political-military planning process and the presidential decision-support process.
+Information actions designed to make the adversary a pariah for having been the first to violate the nuclear taboo since 1945. The purpose of this is to make it difficult, if not impossible, for third parties to side with Russia or China in the wake of their nuclear escalation, and to affect the Russian and Chinese leaderships’ decision calculus regarding further escalation.
+Information actions designed to convince both elements of Russian and Chinese political and military leadership, and the Russian and Chinese populations, that their leaders’ actions are risking large-scale nuclear war and the destruction of their nations in a failing pursuit of nonessential objectives. The purpose of this is to put pressure on the leadership to terminate the conflict.
+Economic actions designed to make clear that the longer the adversaries continue the war, the more long term the economic damage they will incur. This also serves the purpose of pressuring their leaderships to terminate the conflict, though it is not clear that such economic effects can be imposed on a timeline sufficient to affect relatively near-term adversary decisionmaking.
+Finally, Project Atom 2024 asked how U.S. policy, when U.S. nuclear planning and operations comply with the law of armed conflict, might affect U.S. military responses in this scenario. Compliance with the law of armed conflict poses no insurmountable barriers to the United States developing effective military response options in support of the array of potential strategic objectives identified in this paper.
+ +The insights derived from this analysis make clear that there is a need to move beyond thinking only about how to deter aggression and subsequent escalation in wars with multiple nuclear-armed adversaries in the twenty-first century. The failure of deterrence of limited nuclear use would create extremely dangerous circumstances, but there are plausible ways to achieve U.S. and allied strategic objectives without automatically triggering large-scale nuclear war.
+ +Having said that, there is a need to expand the scope of the initial Project Atom 2024 analysis to address the full range of plausible scenarios and strategic circumstances in which the United States and its allies and partners might face the challenge of responding to a failure to deter limited nuclear use in a theater conflict with Russia or China. In the scenario addressed here, the United States and its allies find themselves rapidly and decisively winning the conventional war in both theaters simultaneously. As a result, Russian and Chinese nuclear escalation seems to be motivated by a desire to terminate the conflicts on terms they can accept before U.S. and allied conventional success further worsens the outcome. This is a very different strategic circumstance than a scenario in which an adversary is winning the conventional conflict and seeks to secure rapid victory through limited nuclear escalation, or one in which the United States is forced to consider limited nuclear first use to prevent a decisive conventional military defeat. Analysis of those and other scenarios and circumstances would likely produce new and important insights regarding the four key issues addressed in this project.

+ +Russia and the Euro-Atlantic community now find that their reach exceeds their grasp in terms of their ability to shape the regional order in the South Caucasus. Both remain regionally influential, but their leverage to drive developments is eroding as the South Caucasus is affected by multipolar international politics. The rise of multipolarity is being promoted by the increasing role of a broad set of external actors – most of all Turkey, Iran and China – engaging in the South Caucasus, and by strengthening links between the region and Asia, the Middle East and Central Asia, links that are supplementing the region’s established ties to the US, Europe and Russia. In this context, there is increased local agency in relation to external partnerships (reinforced by a turn to illiberal domestic politics), and waning attraction both to Russian and Euro-Atlantic integration projects.
+ +As a result of these changes, Russia has lost its position of pre-eminence, which rested primarily on tying together its security interests with the region’s protracted conflicts. Over the past 30 years, Moscow has leveraged these conflicts to give it a central geopolitical role, which it has used to promote a regional status quo to its advantage and to create a Gordian knot of interwoven obstacles and interests to hinder efforts at Euro-Atlantic integration. The war in Ukraine has played a part in undercutting Moscow’s position in the South Caucasus, but Russia’s long-term relative decline as new actors have entered the region, power shifts within the South Caucasus itself (notably the rise of Azerbaijan), and changing Russian regional interests are the main factors challenging Moscow’s established role.
+ +Russia is now seeking to adapt to the new regional situation. It is attempting to establish its role as the leading, but no longer exclusive, external actor in the South Caucasus by reconfiguring its position. This involves a rebalancing of bilateral relations, broadening its range of policy tools (notably in the areas of transport and communications) from a previous reliance on security, and being ready to countenance an expanded presence for other external actors, notably regional powers – principally Iran, Turkey and, increasingly, China – while remaining opposed to the US and the EU.
+ +In the absence of a Euro-Atlantic security commitment capable of challenging Russia in the South Caucasus, the policies of enlargement (eventual NATO and EU membership) have lost traction. The Euro-Atlantic community now risks being marginalised in an increasingly competitive regional environment. If it is to undercut Russia’s effort to build a new position – to retie the Caucasian knot – and retain a significant regional role, it will need to develop approaches capable of responding to and shaping the new South Caucasus geopolitics and geo-economics.
+ +Russia is facing a key moment in its post-Soviet position in the South Caucasus (Georgia, Azerbaijan and Armenia). Since the mid-2000s, geopolitical competition between Russia and the Euro-Atlantic community has emerged as a defining issue shaping the regional order. Using security policy – including direct military action – as its primary tool, Russia was able to establish itself both as the main arbiter in conflict resolution and central to the balance of power in the South Caucasus. On this basis, Russia was able to limit NATO and EU enlargement policies, while at the same time seeking to advance its own integration project.

+ +As a result, the South Caucasus became an internally and externally fragmented region (see Figure 1). Countries were divided domestically and regionally by protracted conflicts – Nagorno-Karabakh was contested between Azerbaijan and Armenia, and conflicts emerged over the regions of Abkhazia and South Ossetia in Georgia. Armenia, Azerbaijan and Georgia also developed differing foreign and security policy trajectories and built diverse allegiances. Azerbaijan adopted policies of balancing and neutrality, Georgia aspired to join the EU and NATO, and Armenia became Russia’s ally within the Collective Security Treaty Organization (CSTO) and the Eurasian Economic Union (EAEU). Russia has sought to manipulate and deepen these divisions to give itself a central regional role. In recent years, as President Vladimir Putin has developed a more assertive policy of rebuilding Russia as a “great power”, the South Caucasus has become integral to the Kremlin’s wider ambitions of dominating the Black Sea, and projecting power into the Middle East and the Mediterranean.
+ +The pre-eminence that Russia has established in the South Caucasus over the past three decades is now being eroded by far-reaching shifts in the international regional and domestic environments. These changes have the potential to create a new regional order. A variety of international actors – China, Iran, Israel, the Gulf states and India, among others – has entered the region, offering new diplomatic and political, trade and investment, and security relations, and providing alternatives to both Russia and the Euro-Atlantic community. The governments of Armenia, Azerbaijan and Georgia have sought to widen their space for political action by developing foreign policies to engage with new international actors and to escape from the geopolitical competition between Russia and the West. Together, these developments have diminished the significance of Russia’s security leverage, notably in respect to the contest over Nagorno-Karabakh as Azerbaijan and Armenia seek to finalise a peace agreement, and shifted the South Caucasus towards alternative agendas for trade, connectivity and strengthening multipolarity.
+ +This paper explores the challenge to Russia’s established position in the South Caucasus as the region undergoes significant change, and analyses Moscow’s effort to craft a new regional approach. The findings of the paper are drawn from three principal sources. A review of secondary literature on regional developments in the South Caucasus was supplemented by a workshop conducted in Tbilisi, Georgia, in April 2024 that brought together leading experts on regional issues. In addition, interviews were conducted, in confidence, with officials from the US, the EU and the UK in Washington, DC, Brussels, London, Tbilisi and Yerevan between February and May 2024.
+ +The paper has three chapters. Chapter I examines how in the post-Soviet decades Russia established itself as the leading external actor in the South Caucasus. Chapter II analyses how Russia’s regional position is being challenged, notably by the wars over Ukraine and Nagorno-Karabakh, the appearance of new international actors in the South Caucasus, and by the shift of regional governments to pursuing foreign policies of multi-alignment, made possible by multipolarity, and often in conjunction with increasingly illiberal domestic politics. Chapter III considers the implications of these changes for Russia’s regional position and sets out how Moscow has sought to respond to these shifts to retain a leading role. The paper concludes with the implications of the changes in Russia’s position and the wider shifts in the South Caucasus for the policies of the Euro-Atlantic community.
+ +The South Caucasus has historically played a key role in Moscow’s broader strategic thinking. The conquest of the North and South Caucasus was central to Russian imperial ambitions and involved a prolonged and ultimately triumphant struggle for control over the region with the Ottoman and Persian empires between the 18th and 20th centuries. The defeat of the Ottomans was at the heart of the wider Russian plan to establish dominance in the Black Sea region, including extending state boundaries through the territories of contemporary Ukraine, and expanding influence into the Balkans, as well as through the Caucasus.
+ +This strategic goal of expanding control over the Caucasus was a stepping-stone for Russia to extend its reach into the Middle East and the Mediterranean, notably as it sought naval access to the world’s oceans beyond the limits of its northern ports. During the Soviet era (1922–91), Moscow applied a similar strategic logic to the region, while also seeing the South Caucasus as a buffer zone to the conflicts of the Middle East and, during the Cold War, the threat posed by NATO to the south.
+ +With the collapse of the Soviet Union in 1991 and the emergence of the independent states of Georgia, Azerbaijan and Armenia, Russia initially shifted away from viewing the South Caucasus as integral to its security policy. The new Russian leadership under President Boris Yeltsin focused instead on a Euro-Atlantic vector in its external ties, while its neighbours were a much lower priority. A series of civil wars in the South Caucasus – over Abkhazia and South Ossetia in Georgia and Nagorno-Karabakh in Azerbaijan – involved elements of Russia’s security forces and led Moscow to develop a new security engagement in the region around the deployment of Russian-led “peacekeeping operations”. These missions served to freeze the violence, rather than resolve the conflicts, and opened the way for Moscow to manage, as well as manipulate, the conflicts in subsequent years, including the opportunity to influence regional issues.
+ +From the mid-1990s, growing violent instability in the North Caucasus, notably in Chechnya, drew Russia into a more southern-oriented security and military posture, and promoted a refocus of its foreign and security policy onto the immediate neighbourhood. Notwithstanding the withdrawal of some Russian military facilities from the South Caucasus in the 1990s and early 2000s, notably from Georgia and Azerbaijan, Moscow retained a border guard and military presence in Armenia. This positioning reflected the long-term view in Moscow of the South Caucasus as a buffer to instability from the south and a means to balance Turkey’s regional aspirations.
+ +The growing threat of Islamist terrorism in Russia’s North Caucasus and the launch of the second Chechen war by Putin in 1999 led Russia to strengthen further its military and security focus on both the North and South Caucasus. It was, however, the emergence of growing Euro-Atlantic engagement in the region that led Russia increasingly to instrumentalise protracted conflicts as leverage in an emerging geopolitical struggle with the West.
+ +During Putin’s initial period as Russia’s president (2000–08), and in particular during his second term (2004–08), Russia moved away from cooperative security approaches to regional conflict management, notably through the OSCE, to giving primacy to its own bilateral engagements. Moscow sought to balance betweenArmenia and Azerbaijan over the Nagorno-Karabakh conflict, including through the supply of weapons to both sides. Russian repositioning around Georgia’s protracted conflicts accelerated following the November 2003 Rose Revolution that brought to power in Tbilisi a government seeking closer ties to NATO and the EU. Increasingly, Moscow backed the separatist leaderships of the two breakaway regions of Abkhazia and South Ossetia in opposition to Georgia.
+ +The August 2008 Russia–Georgia war, following the April NATO Bucharest Summit Declaration that Georgia (and Ukraine) would join the Alliance in the future, marked the onset of full-scale geopolitical confrontation in the South Caucasus. Russia’s use of military force was designed to demonstrate that it was unwilling to countenance Euro-Atlantic integration in territories it considered its backyard.
+ +The return of Putin as president in 2012 marked a new phase of Russian policy towards the South Caucasus. The region became fully integrated into Putin’s growing great power ambitions for Russia, and the confrontation with the Euro-Atlantic community. Russia’s military action against Georgia in 2008 directly challenged the Euro-Atlantic community by suggesting that it would need to be ready for war with Russia if it sought to advance membership in European organisations for countries in the South Caucasus. Through this positioning, Putin aimed to maintain a regional status quo favourable to Russia.
+ +While Russia’s security position has been its trump card in the South Caucasus, Moscow has developed other interlinked policy approaches, both to coerce and attract the region. As geopolitical competition with the Euro-Atlantic community strengthened after 2008, Russia increasingly sought to integrate the South Caucasus more closely as part of its efforts to create a “sphere of privileged interests” across the territory of the former Soviet Union. Russia aimed to counter Euro-Atlantic integration efforts through its own integration agenda, focused on the EAEU and the CSTO. Ultimately, only Armenia agreed to join the EAEU – it was already a member of the CSTO – when Russia leveraged Armenia’s security dependence to pressure it to reject an EU association agreement in 2013.
+ +Moscow’s policy mix has been tailored to the countries of the region. With Georgia, the Kremlin has used a stick-and-carrot approach. Initially, Moscow relied on economic coercion and disinformation, while leveraging the protracted conflicts (including periodically raising the prospect of annexing South Ossetia), and the threat of further coercive and even military action against Tbilisi following the 2008 war. With the adoption by the Georgian government of a policy to normalise relations with Russia from 2012, and in particular as the ruling Georgian Dream Party has grown increasingly authoritarian in its domestic policies, leading to a deterioration of ties with the Euro-Atlantic community, Moscow has offered visa liberalisation, the resumption of direct flights between the two countries, increased tourism and the importance of a trade relationship.
+ +With Armenia, Moscow has employed a different approach. It has provided security guarantees through Armenia’s CSTO membership and the presence of Russian military and border guard facilities. Moscow has also offered Armenia favourable economic terms. It has sought to advance Russian investment in the energy and other sectors, while membership of the EAEU has provided Armenia with access to a large market.
+ +In the case of Azerbaijan, Russia has been ready to accommodate flexibility as long as Baku has eschewed seeking NATO or EU membership, while at the same time pledging good neighbourly relations. This has been achieved through the conclusion of a series of partnership agreements over the past two decades (notably the partnership agreement in February 2022), and building cooperation in key economic areas, critically energy.
+ +Over the past two decades, Russia has sought to use its pre-eminent security position, supported by other policies, to limit the three South Caucasian republics’ options for external economic and security ties. The aim of these approaches has been to isolate the South Caucasus strategically while tying it ever closer to Russia. Entangling the conflicts of the South Caucasus with Russian security interests has created a Gordian knot for the Euro-Atlantic community in the region which, in the absence of a readiness to challenge Russia directly for fear of escalation to military confrontation and even war, has been unable to advance substantially its integration efforts.
+ +As competition with the Euro-Atlantic community intensified, the South Caucasus became part of Russia’s broader ambition to project its power around and across the Black Sea. In a return to Russia’s grand strategy towards the South Caucasus, Moscow’s regional engagement was linked to the wider goal of projecting power into the Black Sea region and beyond, into the eastern Mediterranean and the Middle East, as Russia became involved in the conflicts in Syria and Libya. After the 2008 Russo-Georgian War, Russia’s 2014 annexation of Crimea and its intervention in eastern Ukraine, the military and security dimensions of the South Caucasus were strengthened through enhancing the network of Russian military bases in Abkhazia, South Ossetia and Armenia (see Figure 1), and promoting the integration of these facilities with the regional network of Russian military facilities.
+ +By the 2020s, Russia appeared to have largely achieved dominance in the South Caucasus. Moscow’s approach to the region had effectively halted Euro-Atlantic integration while gradually strengthening its own position. In 2020, when Azerbaijan launched the Second Nagorno-Karabakh War, Russia aimed to advance its regional role with the introduction of “peacekeepers” into the conflict, something it had sought for over 20 years. These developments led to interpretations that Russia was consolidating its regional pre-eminence. In fact, the South Caucasus was already experiencing a set of interrelated shifts that have together undermined the regional position that Russia built up in the post-Soviet period.
+ +In recent years, the foundations of Moscow’s dominant regional position, built in the context of geopolitical and geo-economic competition with the Euro-Atlantic community, have been challenged by three interlinked developments.
+ +First, the Second Nagorno-Karabakh War (2020 and 2023) created a new regional balance of force and the emergence of economic and connectivity opportunities that have undercut security agendas. Second, a set of external actors has entered the region, providing alternatives to Moscow, Brussels and Washington, and tying the South Caucasus more closely to the Middle East, central Eurasia and Asia. Third, Russia’s war in Ukraine initially led to a questioning of Moscow’s ability to project security and military force in the region, while the prolonged nature of the war has reinforced hedging strategies by countries in the region unsure of who will ultimately be victorious. Together, these developments are promoting foreign and security policies of multi-alignment in the South Caucasus, as regional governments seek to develop multiple external partners to balance and hedge against the dominance of Russia and the Euro-Atlantic community.
+ +The most significant development within the South Caucasus region has been Azerbaijan’s military actions in 2020 and 2023 to take back territory occupied by Armenia following the First Nagorno-Karabakh War (1988–94), and ultimately to reclaim control over the Nagorno-Karabakh region itself. As a result, Azerbaijan has emerged as the regional agenda setter and has attracted Russia’s interest.
+ +For Armenia, there has been a deterioration in the Armenia–Russia alliance as a result of Russia’s failure to restrain Azerbaijan in 2020 and the inability – and possibly unwillingness – of Russian “peacekeepers” to prevent the seizure of the whole of Nagorno-Karabakh in 2023. This led to the flight of the ethnic Armenian population amid claims of ethnic cleansing – along with a perception that Moscow is more interested in developing a close relationship with Baku.
+ +Armenia has signalled publicly that it is ready to shift away from its reliance on Russian security guarantees and seek closer relations with others, notably the US and the EU (especially France). Prime Minister Nikol Pashinyan has indicated that Armenia has suspended its participation in the CSTO – having previously indicated that it would leave the organisation – although he has not closed the door to a future relationship, and Russian border guards have been removed from Yerevan airport. With the Nagorno-Karabakh conflict resolved by military force, Russia is no longer able to leverage its role as a mediator, while the prospect of a peace agreement between Armenia and Azerbaijan, potentially also leading to Armenia–Turkey normalisation, will further reduce Moscow’s ability to leverage its security role. With the war in Ukraine also redefining Russian regional interests, Moscow has begun to reshape its approach to the South Caucasus.
+ +While the period since 2008 has been marked by geopolitical competition between Russia and the Euro-Atlantic community in the South Caucasus, states within the region are increasingly reaching out to a wider network of partners to help them to manage geopolitical competition and expand economic opportunities.
+ +Turkey
+ +The growing influence of Turkey has relied to a significant degree on its strategic alliance with Azerbaijan and the coordinated approach that the two countries have taken to Armenia and the Nagorno-Karabakh conflict, as well as energy projects. Since 1992, they have forged close military, diplomatic and economic ties. Turkey has notably provided Azerbaijan with important military capacities and training. This relationship was central to the 2020 Second Nagorno-Karabakh War, in which Turkish military technologies played an important role, but even more significant was the ability of Turkey’s President Recep Tayyip Erdoğan to balance diplomatic efforts by Putin to shape the outcomes of the conflict to Russia’s advantage. Since then, Turkey and Azerbaijan have coordinated efforts to position the South Caucasus as the gateway to the Middle Corridor, which links Europe through the Caspian region to Central Asia and western parts of China, and to accelerate work on this initiative.
+ +Although Azerbaijan is Turkey’s key regional ally, Turkey has been exploring deeper ties with Georgia, reflecting the country’s key transit role for energy, transport and trade. Turkey identifies relations with Georgia as a “strategic partnership”, supports its territorial integrity and does not recognise claims by Abkhazia and South Ossetia for independence. Turkey is Georgia’s leading trade partner, ahead of Russia and China, and Ankara views Georgia as a critical partner in its plans for the development and expansion of the Middle Corridor. Turkey has also sought to develop its security ties to Georgia, including as part of a trilateral format with Azerbaijan, and has been a supporter of closer ties between NATO and Georgia. Turkey’s role has also been important as part of a broader strengthening in relations between the South Caucasus and Middle Eastern countries that has included rising trade and deepening diplomatic ties, notably with Saudi Arabia, but also with Iraq and Jordan (as well as Iran and Israel).
+ +Iran
+ +Iran does not have the levels of regional influence achieved by Russia and Turkey, in part reflecting its strategic view of the South Caucasus as a buffer region. Tehran’s approach has been focused on preventing overspill from the region into Iran. It hopes to balance the influence of regional rivals (Turkey and Russia) and ensure that the South Caucasus does not become a base of operations for states seen as hostile to Tehran (principally the US and Israel). As the third regional neighbouring state it has, nonetheless, built ties with Armenia, while managing a complex and occasionally confrontational relationship with Azerbaijan.
+ +As the South Caucasus has begun to open to greater connectivity, gaining access to Iran’s trade and transport routes has risen in importance. Tehran has developed a more forward-leaning foreign policy towards the South Caucasus and has sought to improve its relationship with Azerbaijan and adopt a more balanced approach to the countries in the region. This has led to an emergent closer relationship with Georgia.
+ +Along with Russia and Turkey, Iran shares an interest in limiting the role of the Euro-Atlantic community in the South Caucasus, and Tehran has supported efforts to advance the “3 + 3” South Caucasus Regional Cooperation Platform format, aimed at bringing together Iran, Turkey, Russia and the South Caucasus countries. Iran has also recognised the strategic importance of efforts to shape a new regional transportation network as part of a peace agreement between Armenia and Azerbaijan. Crucially, Tehran has opposed efforts to open the so-called Zangezur Corridor, the proposed transport link between Azerbaijan and its exclave Nakhchivan across the southern Armenian region of Syunik, fearing it would impede its trade links northwards and strengthen Turkey’s regional position, even when this has led to friction with Russia.
+ +Despite strains in the Iran–Russia relationship, there has been a strategic convergence between Tehran and Moscow as a result of the Ukraine war, which is being formalised through a proposed partnership treaty that will include regional security issues, alongside a free-trade agreement to link the EAEU to Iran. Iran’s evolving engagement in the South Caucasus, and notably its cooperation with Russia in the area of transport, form an important element of the growing alignment between the two countries.
+ +Israel and the Gulf States
+ +After Turkey, Israel has been Azerbaijan’s most important external partner in military, investment and diplomatic support. Azerbaijan has looked to Israel to provide it with key military capabilities, as well as technologies to advance its ambitions to move its economy away from reliance on hydrocarbon production. Azerbaijan has become a significant energy supplier to Israel. Israel has, on the other hand, had modest relations with Georgia and Armenia, and its engagement in the South Caucasus has served primarily to reinforce Baku’s international options and capabilities, rather than to play a regional role. At the same time, Iran’s concern about a potential Israeli security presence in Azerbaijan has fed into Tehran’s broader foreign and military approach to the South Caucasus, notably into an effort to weaken Baku through support for Armenia.
+ +Building on their established links to Azerbaijan, Gulf states are increasingly looking to the South Caucasus for investment and trade opportunities, particularly in the energy and transportation sectors.
+ +China and Central Asia
+ +China’s presence in the South Caucasus has been growing through trade and tourism, as well as infrastructure projects. The new international interest in transport corridors through the South Caucasus, in part created by the wars in Ukraine and the Middle East, has increased China’s engagement in the region as it seeks to develop “the Great Silk Road” as part of its global Belt and Road Initiative. The award to a Chinese-led consortium of a contract to build the Anaklia deepwater port in Georgia is a particular focus for Beijing as part of its effort to build transport infrastructure connecting China’s economy to European markets.
+ +The pull of China in relation to economic and trade issues is also drawing the countries of the South Caucasus to the east in their external relations, as efforts to develop the Middle Corridor accelerate. While the central approach of China in the South Caucasus appears to be geo-economic, its growing interest in Georgia has been linked to the erosion of democratic practices through rising elite corruption, while also being seen to reinforce the broader regional shift of foreign policy – away from the Euro-Atlantic community.
+ +To cement its developing regional role, China has sought to conclude “strategic agreements” with Georgia and Azerbaijan. Baku has made the most significant shift to the east, even raising the prospect of joining regional formats, and President Ilham Aliyev has attended the Central Asia head of state consultative meetings, as well as forging bilateral and minilateral ties with countries across that region. The transport connectivity agenda is, however, exerting a pull on all the South Caucasus countries, pushing them to develop ties linking the Black and Caspian Sea regions.
+ +India and Pakistan
+ +India and Pakistan are relatively minor international actors in the region, but India has been increasing its arms sales, notably becoming a primary supplier to Armenia, while Pakistan has concluded defence agreements with Azerbaijan. Pakistan has sought to track India’s growing regional ties as an extension of their bilateral rivalry. Relations with the South Caucasus also reflect India’s long-term plans to build new trade and transport routes from South Asia across Eurasia to Europe, linking the region to the Gulf and the Indian Ocean. These new ties are becoming the basis for competing groupings, with India seeking to cooperate with Iran and Armenia, and Pakistan looking to partner with Turkey and Azerbaijan.
+ +The emergence of a multitude of international actors in the South Caucasus is changing the region’s international environment. While Russia and the Euro-Atlantic community remain key reference points, reflecting their continuing regional strategic weight, new actors are offering additional security, economic and transport relationships. Minilateral formats are emerging to reflect new partnerships and blending of interests, and some South Caucasus states are looking to participate in larger multilateral formats, including the Shanghai Cooperation Organisation, the BRICS (Azerbaijan announced its application to join in August 2024), and the Organization of Turkic States.
+ +For countries in the region, this approach to external ties is driven by two main interests. First, governments are pursuing balancing approaches to serve as counterweights to external integration projects that seek to curtail the position and interests of domestic elites, whether it is via Russia’s efforts to shape pro-Moscow regimes or the Euro-Atlantic community’s democracy, human rights and rule of law agenda challenging illiberal and kleptocratic regimes. Second, the broadening of external contacts has enabled countries in the South Caucasus to increase their leverage, and notably to hedge their dominant bilateral ties to Russia and the Euro-Atlantic community, in order to improve their bargaining position.
+ +The development of this dimension of regional politics is, however, also a source for new instability in the region, with countries now linked to various disputes and competition beyond the South Caucasus, for example the tensions between Turkey and Israel over Gaza and Lebanon have unsettled their ties to Azerbaijan. It is also difficult for external actors to develop a stable approach to the region, as the regional governments are able to switch external partners and play them against each other to secure better offers.
+ +Russia’s invasion of Ukraine in February 2022 created shock waves across the South Caucasus. Initially, Russia pulled forces from the region to reinforce its struggling troops in Ukraine. As Moscow faced difficulties in overcoming Ukrainian forces, questions were raised in the region about the effectiveness of Russia as a military and security actor. The war also increased external pressure on the governments in the South Caucasus to take sides in the conflict, including through observing Western sanctions on Russia.
+ +Georgia, concerned about the Russian threat to its own territories, distanced itself from Kyiv and refused to apply sanctions. Azerbaijan sought to maintain its policy of balancing, providing limited support to Ukraine, agreeing to supply extra gas volumes to Europe as it sought to diversify its energy markets, and emphasised its crucial geographic position at the heart of the Middle Corridor as an alternative to Russian transit routes. At the same time, Baku sought to maintain its strategic relationship with Moscow. Armenia, given its reliance on Moscow and questions about the effectiveness of Russian forces and the ability of Russia’s defence industry to supply weapons, began to recalibrate its security partnership with Russia.
+ +As the Ukraine war has continued, the impact of the conflict on the South Caucasus has shifted. With considerable uncertainty about the outcome of the war, all three South Caucasus states have sought to avoid being too overtly tied to one side and have pursued different balancing options. There is also concern that if Russia is victorious in Ukraine, it may then look to strengthen its control over the South Caucasus as the next step in efforts to expand Russia’s regional power, and so the prudent approach is to avoid taking sides.
+ +At the same time, the Ukraine war has reshaped Russia’s own interests in the South Caucasus. As a result of the war and Western sanctions, the South Caucasus has become critical to Russia’s efforts to reorient trade and communications away from Europe. This has led Moscow to rebalance its regional relations, with Baku becoming central to Russia’s regional transportation plans.
+ +Faced with the current shifts across the region, Russia has sought to craft a new balance of policies so that it can reposition itself and remain at the heart of the South Caucasus regional order.
+ +Despite the emergence of new policy tools, Moscow continues to use security issues to shape the region towards its interests. The ongoing occupation of Abkhazia and South Ossetia and their steady integration into Russia remains a defining point in Moscow’s regional position. As the relationship between Georgia and the Euro-Atlantic community has frayed, as Tbilisi has adopted increasingly anti-democratic domestic policies and continued to develop ties with Russia, Moscow has rebalanced its approach from threat to inducement around the protracted Abkhaz and South Ossetian conflict. Before the Georgian elections on 26 October 2024 Moscow hinted that it would be ready to help Tbilisi “normalise” relations with the two breakaway regions.
+ +At the same time, the fact that the Euro-Atlantic community has not been prepared to challenge Russian military occupation of Abkhazia and South Ossetia directly signals to the wider region the limit of EU/NATO regional commitment. While Russia’s policy towards Georgia remains a clear indication that Moscow will not countenance Euro-Atlantic integration in the region, its ability to bind the wider region through security ties has, however, corroded, notably with the resolution of the Nagorno-Karabakh conflict and the subsequent shift by Armenia towards a broader range of security partners.
+ +Since its defeat in the Second Nagorno-Karabakh War, Armenia has signalled strong dissatisfaction with the Russian security guarantee, and there has been an escalation of negative rhetoric regarding Moscow’s role. Yerevan has taken steps on the margins of its security relationship with Moscow to underline its discontent, opened to a wider range of external relationships, including with the Euro-Atlantic community, and begun to rebuild its military through partnerships with Europe, India and the US. While Armenia may be able to “navigate a path away from Russia” through diversifying its security partnerships, there are real limits on how far Armenia can push, at least in the medium term. It has become clear since 2020 that Russian security protection does not extend to actions by Azerbaijan. However, ultimately, only Moscow is willing to give security guarantees to Armenia when it believes it remains vulnerable to other external threats, notably from Turkey, and there continues to be security interdependence between Russia and Armenia. Moscow may also be ready to threaten more direct responses to Armenia if it veers far from Russian interests.
+ +Azerbaijan has sought to diminish Russia’s security leverage, notably through a commitment over several decades to building ties to other military partners (Turkey and Israel). But an equally important element of managing the Russian security threat has been Baku’s decision to eschew EU and NATO integration – a decision taken to a significant degree in light of the lesson of the 2008 Russo-Georgian War that the Euro-Atlantic community is not ready to challenge Russia militarily in the region. To underline that it does not seek to break away completely from Russia, Azerbaijan has sought to identify a positive agenda of alternative policy areas for cooperation with Russia where it can shape a partnership in its interests.

+ +Moscow’s most important policy shift regarding the changing political and economic dynamics of the South Caucasus is the new emphasis given to the region as a zone for trade and communications (see Figure 2). The breakdown of ties with the Euro-Atlantic community, the imposition of sanctions and the closing of some markets has effectively forced Russia to reorient its economic policy on a north–south axis, away from the previous east–west axis. Moscow’s efforts to reorient its external economic relations, as part of the wider shift in its foreign and security relations brought about by the Ukraine war, are already having significant results, as trade along a north–south axis, notably with Iran and India, has increased substantially in recent years.
+ +In this context, the key project for Russia is the International North–South Transit Corridor (INSTC), a series of rail, ship and road routes connecting Russia to Iran and its Gulf ports and beyond, to South and East Asia. The most promising route goes through Azerbaijan, the only country that borders both Russia and Iran, and which already has a railway connecting Russia and Iran. While the INSTC has been on the drawing board since 2005, it has gained new impetus since the war in Ukraine and Western efforts to isolate Russia economically. In May 2023, Russia and Iran agreed to complete, by 2027, the construction of a railway from the Iran–Azerbaijan border, at Astara, to Rasht in northern Iran, which represents the last missing rail link to connect St Petersburg to the Gulf. Realisation of the INSTC is a strategic goal for Moscow, supported by Iran and India, but Russia is likely to be the main funder of any new infrastructure, in view of its pressing need to bypass Western sanctions.
+ +The focus on connectivity in the South Caucasus is giving Russia a new direction for its security policy. Russia is aiming to assert a security role in the South Caucasus transport network to unblock the regional transport network on its terms and, thereby, provide Moscow with important regional leverage. For this reason, the Zangezur Corridor has become a particular focus for Russian diplomacy and a key interest in the wider Armenia–Azerbaijan peace negotiations.
+ +Citing provisions on Russian security personnel managing the land corridor in the 2020 Armenia–Azerbaijan ceasefire agreement brokered by Moscow, the Kremlin insists on its presence along the corridor. If it were able to exert influence on the region’s transport networks, Moscow would gain new leverage over the countries of the South Caucasus, including Georgia, which currently is the main axis for north–south trade. Russia has sought to channel negotiations on transport links into the 2021 tripartite commission on this issue that it convenes with Armenia and Azerbaijan, and into key bilateral formats.
+ +A third key component of Moscow’s evolving policy towards the South Caucasus is a deepened partnership with Baku. Azerbaijan has emerged as the leading regional state as a result of its military successes against Armenia, its ability to build a latticework of external partners, and its balancing policy towards Russia. Indeed, Azerbaijan is now essential for Russia in terms of energy exports and its transport links to Iran. The Kremlin has stressed that Azerbaijan is a “stable” partner in the region, and has spoken of the bilateral relationship in warm terms as having an “alliance” character.
+ +Azerbaijan has been able to use its newfound regional leverage to bypass Russia’s efforts to manipulate regional conflicts – ignoring Russia’s demands over Nagorno-Karabakh, forcing the withdrawal of Russian peacekeepers, and sidelining Moscow’s role in mediating the Armenia–Azerbaijan relationship – all while maintaining a degree of support for Ukraine. But Baku has lined up behind Russia on Moscow’s interests where they largely align with those of Azerbaijan. Together with Russia, Azerbaijan has been critical of Armenia’s efforts to reach out to the Euro-Atlantic community, and it has opposed the deployment of an EU border-monitoring mission to the region. Azerbaijan is also publicly supporting Russia’s position on transport corridors across Armenia, even if there are suspicions that Baku would also be keen to leave Russia out of the route.
+ +While Azerbaijan is now Russia’s main regional partner, Moscow is paying close attention to contemporary developments within Georgia. Since the Rose Revolution, Georgia has been the anchor of the Euro-Atlantic community’s regional engagement, and in 2023, the EU granted Tbilisi candidate status. However, despite movement on some bureaucratic processes, the integration of Georgia into the Euro-Atlantic community has been effectively frozen following the 2008 Russo-Georgian War, reflecting the reluctance of the US and its European allies to challenge directly Moscow’s security commitment to Abkhazia and South Ossetia.
+ +Since the Georgian Dream political party – established and led by the billionaire Bidzina Ivanishvili – entered government in Tbilisi in 2012, Georgia has followed a twin-track policy of seeking to advance NATO and EU memberships while also pursuing a policy of gradual normalisation with Moscow. With Euro-Atlantic integration unable to make real progress and with the turn to increasingly authoritarian domestic politics in Georgia in recent years, the relationship between Tbilisi, Washington and Brussels has deteriorated significantly.
+ +At the same time, the normalisation process with Russia has continued, even in the difficult context of the war in Ukraine. While there is little evidence that Russia has driven the breakdown in ties between Georgia and the Euro-Atlantic community, Moscow has opportunistically sought to benefit. The Georgian government has also given the impression that it is ready to move closer to Moscow if the US and Europe continue to set democracy and human rights conditions that are unacceptable to Georgian Dream.
+ +Against this background, the October 2024 parliamentary elections were seen as a critical test of Georgia’s future. With Georgian Dream claiming victory in the disputed elections, relations with the Euro-Atlantic community appear set to deteriorate further. Following the election, the US and European countries called for an investigation into how it was conducted and, in particular, the steps taken ahead of the vote by the ruling party to ensure its victory. US President Joe Biden publicly raised concerns about the decline of democracy in Georgia.
+ +At the same time, having offered ahead of the election to facilitate Georgia’s territorial disputes as a means to promote support for Georgian Dream, Moscow will need to demonstrate that it can deliver progress on a new relationship between Georgia and the two breakaway regions that will satisfy Tbilisi. Given Moscow’s strategic investment in the nominal independence of these regions, the prospects of significant shifts over the status of Abkhazia and South Ossetia are, however, slim, likely placing an important check on how far Russia–Georgia rapprochement can advance. The Georgian government may well move closer to Russia to test Moscow’s offer, but is likely to continue to pursue multi-alignment in its foreign and security policies rather than joining Russia’s regional organisations such as the CSTO or the EAEU.
+ +As an economic actor, Russia remains vital for the countries of the South Caucasus. Indeed, sanctions on Russia over its invasion of Ukraine have strengthened interdependence between Russia (and, via the EAEU, Belarus and Central Asia) and the countries of the region. The Ukraine war is having far-reaching impacts on the geo-economics of the South Caucasus, with the region’s role as an energy and trade corridor becoming even more significant, notably for Russia.
+ +Georgia serves as an example for Moscow of how – despite the political tensions between the two governments over the occupied territories – economic cooperation has a positive impact on relations. Indeed, trade with Russia has continued to be strong in recent years. Since 2021, Georgia’s economic dependence on Russia has increased, with some sectors reliant on the Russian market. For example, in 2023, wine exports to Russia increased 5% on the previous year, with the Russian market taking 65% of Georgian wine exports, the highest level since 2013. Although there is widespread Georgian public distrust and even hostility to Russia, views on closer economic relations are mixed.
+ +For Armenia, despite the political rhetoric about souring ties, economic relations continue to flourish, with a notable rise in exports following the onset of the Ukraine war – widely seen as a result of Armenia (alongside Georgia) becoming a route to Russia for goods that avoided sanctions. Russia is Armenia’s largest trading partner, with an overall foreign trade volume in 2023 of more than 35% and notably 49.6% of Armenia’s imports coming from Russia. In 2022, the volume of trade between Armenia and Russia nearly doubled, a trend that continued through 2023 and the first months of 2024. In 2023, Russia’s over 35% share of the country’s foreign trade contrasted with the EU’s 13%. Russian companies also have considerable investments in Armenia, notably owning key parts of the energy sector and the railways, and make a substantial contribution through taxes to the national budget.
+ +For Azerbaijan, which has sought to diversity its economic as well as security policy, economic ties with Russia are following a similar trajectory to its neighbours. In 2023, trade between Azerbaijan and Moscow was reported to have risen by 17.5%. Bilateral energy trade has also developed in recent years.
+ +It would appear that Russia has implicitly accepted that it can no longer maintain primacy in the South Caucasus and that other, notably regional, powers will have roles. The Russian regionalisation policy aims at intensifying dialogue, coordination and interaction with the main regional powers engaged in the South Caucasus. Moscow has, however, tried to maintain a regional leadership position through seeking to manage informal cooperation – and competition – with Turkey and Iran. Iran has become a key ally for Russia on the international stage and both countries share an interest in developing closer ties and north–south trade links. On 25 December 2023, the EAEU signed a free-trade agreement with Iran that will eliminate customs duties on almost 90% of goods, thereby linking Russia’s regional economic integration initiative to its efforts to build a wider bloc of friendly countries beyond the post-Soviet space. While Turkey and Russia cooperate and compete in various theatres (often articulated through tactical alliances), including in the South Caucasus, they share an interest in establishing a new regional strategic equilibrium around a potential peace settlement of the Armenia–Azerbaijan confrontation.
+ +Institutionally, Russia supports the 3 + 3 South Caucasus Regional Cooperation Platform format, which sets the stage for the direct participation of Iran and Turkey in determining the future of the region – although Georgia has, to date, boycotted the grouping. Speaking at the October 2024 meeting of the 3 + 3 format, Russian Foreign Minister Sergei Lavrov indicated that Armenia and Azerbaijan should use the platform to negotiate their peace agreement.
+ +A resolution of the bitter Armenia–Azerbaijan relationship through a peace agreement and subsequent process of normalisation stands at the centre of the potential transformation of the South Caucasus. Agreement between Baku and Yerevan would open the region for investment in transport, trade, energy and communications projects, unlock closed borders, and create some of the conditions for Armenia–Turkey normalisation. The nature of an agreement would also have a profound impact on the balance of power within the South Caucasus. For these reasons, the negotiations between Armenia and Azerbaijan have become a focus of external actors, with Russia, the EU (notably France and Germany) and the US jockeying for influence and a role in the negotiations.
+ +With Azerbaijan’s victory in its two military campaigns in 2020 and 2023 to reclaim the occupied territories and the Nagorno-Karabakh region, Russia’s previous leverage around the protracted conflict collapsed as the OSCE Minsk Group process (the diplomatic mechanism established in 1992 to facilitate negotiations to end the conflict over Nagorno-Karabakh under the co-chairmanship of the US, Russia and France) was marginalised, Moscow’s leverage as the leading arms supplier to both sides evaporated, and Baku sought to move negotiations between different formats and ultimately to push successfully for direct bilateral Armenia–Azerbaijan contacts as the way forward to exclude third parties (principally Russia, the US and the EU).
+ +With the departure of Russian “peacekeepers” from Nagorno-Karabakh in April 2024, as well as pressure on the Russian relationship with Armenia, Moscow’s ability to use security to shape developments on the ground has been undermined. Instead, it has sought to reposition itself diplomatically to shape developments so that an eventual peace agreement would also serve Russian interests.
+ +Moscow’s goals have been to ensure that Russia has a central role in any agreements about the future shape and management of land transport and communications infrastructure in the South Caucasus, that the Euro-Atlantic community is marginalised, and that the region’s immediate neighbours (Russia, Turkey and Iran) emerge as the key regional arbiters – with Moscow in the lead role. Russia has sought to insert itself into the key issue of a transport corridor across Armenia and to ensure that the INSTC, which is vital to its ability to build economic and trade links to the south, goes ahead. Moscow views a role in these areas as critical to ensuring its regional influence, notably in the Armenia–Azerbaijan relationship.
+ +The partnership with Azerbaijan has become central to Russia’s efforts to advance this agenda – notably as the transatlantic community has increasingly aligned to support Armenia, leading to growing tensions with Baku. In August 2024, the visit of Russian Security Council Secretary Sergey Shoigu to Baku underlined how the variety of Russian regional interests are now being channelled through the bilateral relationship. In a meeting with President Aliyev, Shoigu highlighted the intersection of the peace negotiations, the development of the INSTC and the future agenda of the 3 + 3 format to manage the stabilisation of the South Caucasus, with efforts to prevent Western “meddling” in the region.
+ +For most of the past two hundred years, Russia has pursued relatively stable strategic goals in relation to the South Caucasus region. At the core, Russia has focused on binding the region to itself, as a buffer zone against external encroachment. In more expansionist foreign policy phases, such as since the turn of the 21st century under Putin, the region has been seen as integral to ambitions to extend Russia’s influence and control in the Black Sea and Caspian Sea regions, as well as the Middle East. At such times, the territories and peoples of the South Caucasus have also often been viewed by Moscow as part of a wider Russian world.
+ +With the South Caucasus undergoing a transformation, notably as result of geopolitical and geo-economic trends towards multipolarity, Russia’s regional role is displaying elements of continuity, but is increasingly characterised by change. Much of the analysis of the region sees Russia as experiencing a “managed decline” or loss of hegemony because of this process of change. The analysis in this paper, however, points to a different conclusion. Moscow is attempting to refashion its position through a renewed regional approach – seeking to retie the Caucasian knot to ensure a continuing central role for Russia in the South Caucasus, retain close links to countries in the region, and marginalise the Euro-Atlantic community.
+ +Over the past two decades, geopolitical competition with the Euro-Atlantic community in the region has been the key challenge to Russia’s ability to achieve its longstanding strategic goals. In this struggle, the Kremlin has deployed security policy as Russia’s trump card. Up until 2020, it was customary to assume that Russia’s goal in the South Caucasus was to use its security advantage to preserve a favourable status quo. Moscow’s current policy towards the region reflects a shift in some respects from this approach and indicates a changed significance of the South Caucasus in Russia’s strategic calculus.
+ +Moscow has recognised that the changes in the international politics of the South Caucasus towards multipolarity have provided opportunities for the countries in the region to pursue policies of multi-alignment. This has meant that Russia can no longer approach the region as though it remains part of the post-Soviet space where it has an exclusive role, and some of its past policy levers have lost traction – notably in respect to the Armenia–Azerbaijan conflict. At the same time, the breakdown of ties with Europe and the US has forced Moscow to seek to reorient its foreign and economic ties south and east.
+ +Russia now looks on the South Caucasus not just as a buffer against the Euro-Atlantic community and a means to strengthen its power projection ambitions in the Black Sea and the Middle East, but also as a vital link to Iran, as well as the location of potential southern routes to access markets and build political and security ties across Eurasia. Russia is therefore rebalancing and realigning its policies to continue to be a central regional player in the South Caucasus, even if this requires a shift from its previous reliance on security policy and the ambition to exclude other external powers from the region.
+ +Moscow is today willing to accommodate and even cooperate with other international actors, notably Iran, China and even Turkey, in the South Caucasus, and it has also adapted by developing new and varied bilateral ties with the three South Caucasian states to shape the regional agenda, particularly on economic and transport issues. However, the Kremlin remains focused on blocking Euro-Atlantic integration efforts in the region, and is willing to work with other regional powers to advance this goal. Indeed, Moscow is now looking to develop its new approach in the South Caucasus as part of a larger Eurasian security initiative, driven, together with China, Iran and other partners, as a counter-West bloc.
+ +Moscow is also experiencing real challenges in forging a new approach to the South Caucasus. It is having to contend with an increasingly complex region in which not only is there a diversity of other, often competitive, external actors, but also the governments of the region have a new degree of agency in developing their foreign relationships. As a result, Moscow is facing resistance to its efforts to insert itself within the central issues that could reshape the regional order, notably the Armenia–Azerbaijan peace agreement and the associated initiatives to open the region’s transport network.
+ +Faced with the prospect of being marginalised from the peace process, Putin made a rare state visit to Baku in August 2024 to promote Moscow’s regional role. The visit was marked by positive words, photo opportunities and commitments to cooperation (notably on the INSTC). Putin appeared, however, unable to reverse the steps that have seen Russia pushed out from its former regional role. Critically, since the early 1990s, Russia – together with the US and Europe – has been at the centre of diplomatic efforts to resolve the Armenia–Azerbaijan conflict. Since 2020 and the Second Nagorno-Karabakh War, Baku has, however, managed to exclude major third parties from discussions, even turning to Kazakhstan to host peace negotiations.
+ +During his visit to Baku, Putin indicated, with a degree of desperation, that he would “be happy” to serve as a regional peacemaker, but neither Baku nor Yerevan has responded positively. At the same time, the decision of Armenia and Azerbaijan to exclude the issue of the Zangezur Corridor from discussions on a peace agreement struck a direct blow to Moscow’s efforts to reinsert itself between the two countries, leading to further, unsuccessful Russian diplomatic efforts.
+ +Russia’s South Caucasus policies are thus at a key moment. Moscow has recognised the importance of the shifts taking place in the region and is taking action to try to ensure that it remains a key regional player. Despite the advantages that Russia has as a consequence of history and geography and the country’s strong security policies, it is nevertheless facing a struggle to reposition itself in the South Caucasus. There is a real prospect that the Kremlin’s efforts to forge a renewed regional role may prove unsuccessful, and Moscow may emerge from the process of realignment a significantly reduced regional force. The high-level political engagement in the region, notably signalled by Putin’s visit to Baku, suggests, however, that the Kremlin is prepared to commit significant political capital to ensure that Russia remains a leading regional actor, and to show that Moscow is not ready to accept a diminished role.
+ +The changing geopolitics of the South Caucasus and Russia’s shifting regional approach pose a challenge for the Euro-Atlantic community. Over the past two decades, the prospect of eventual EU and NATO integration has been the main policy framework to build support and attract regional states. The approach marries values – in support of human rights, rule of law and democratisation – with a geopolitical approach to counter Russia and its integration offer, notably through access to European markets and financial assistance.
+ +Since 2008, Moscow has, however, been able to thwart Euro-Atlantic integration through its dominance of regional security politics. Unwilling to challenge Russia’s security trump card, the Euro-Atlantic community has officially followed an open-door policy for NATO and EU membership for Georgia, and maintained a readiness to advance ties to Azerbaijan and Armenia if there is an opportunity. In reality, the EU and NATO tracks have effectively been stalled, even in the case of Georgia, which has been at the forefront of building ties.
+ +With shifts in the international politics of the South Caucasus, a policy built on “strategic patience” is well past its expiry date. The changes that have affected the South Caucasus have shifted the region from being an exclusively European security region, as it was in the decades after the collapse of the Soviet Union, to one increasingly linked to the Middle East, South Asia and China. The countries of the South Caucasus now have alternative partners to the Euro-Atlantic community (and Russia), notably for trade, infrastructure investment and business, but also for the supply of weapons and for diplomatic ties. While these ties may lack the potential of Euro-Atlantic integration, they offer immediate and tangible gains, especially in comparison to the promise of a bright future of EU and NATO membership that never seems to quite arrive.
+ +The links to other external actors generally also come without the formal conditionality attached by the Euro-Atlantic community. The development of multipolarity has, in this way, reinforced the ability of local elites to advance illiberalism. As a result, Russian-style authoritarian politics has taken hold in Georgia and is consolidated in Azerbaijan, while democratisation remains fragile and vulnerable in Armenia. With this shift, the idea that the region will become part of the Euro-Atlantic community through eventual EU and NATO membership looks unrealistic.
+ +This presents a dilemma for the Euro-Atlantic community: either continue to criticise non-democratic governments and risk them shifting orientation to Russia and others, or try to retain engagement but then face working with regimes that do not reflect Western values. In either option, Euro-Atlantic integration will struggle to advance. In recent years, Georgia has represented this challenge most starkly. The adoption of increasingly antidemocratic practices by Georgian Dream, the ruling party, and the cultivation of a diversity of external ties have seen a withdrawal of Euro-Atlantic security and economic support. After decades of effort to advance Tbilisi as the key Euro-Atlantic partner in the South Caucasus, Georgia was largely absent from the Washington NATO Summit Communique in 2024. An EU report on Georgia’s progress towards membership that appeared immediately after the October 2024 election appeared to indicate that the membership process was effectively frozen.
+ +As the Euro-Atlantic position has weakened in Georgia, there has been an effort to pivot to Armenia, including supplying security assistance and even military equipment. This will add little to Armenia’s overall defence and deterrence, but the shift risks being seen as taking sides within the region, further accelerating the militarisation of the South Caucasus and contributing to the emergence of a new round of internal divisions just as the prospects of a new regional settlement are emerging. In any case, Armenia’s prospects for Euro-Atlantic integration will be constrained by the same developments that have affected the other countries of the region – Russia’s readiness to use its range of policies, and centrally its willingness to use security and military tools, to prevent Euro-Atlantic enlargement, and the appearance of attractive alternative international partners.
+ +The risks for the Euro-Atlantic community of failing to find an effective means of engagement in the region are highlighted by Azerbaijan. Having turned away from Euro-Atlantic integration, Baku has been able to consolidate its authoritarian political order and reclaim the occupied territories and Nagorno-Karabakh, employing approaches that have led to ethnic cleansing. Euro-Atlantic actors appear largely powerless regarding either development. Indeed, Europe has been keen to develop closer energy and transport links to Azerbaijan, even as Baku has followed this domestic and foreign policy course.
+ +The Euro-Atlantic community must now look at the emerging regional realities and craft a regional policy capable of influencing contemporary developments. Given the broader confrontation with Russia, weakening Moscow’s presence in the South Caucasus and disrupting its efforts to rebuild a new regional position for itself should be at the heart of a regional strategy for the Euro-Atlantic community. A key emphasis should be on countering Moscow’s efforts to position itself in the regional trade and communications infrastructure to support its war effort and reinforce its strategic partnership with Iran.
+ +The focus of Western policy should be on strengthening the sovereignty and independence of regional states and their ability to balance Russia through multi-alignment (in which context the Euro-Atlantic community can remain a leading partner), and to undermine Russia’s efforts to control them or to shepherd them into regional and international formats (such as the 3 + 3 and the BRICS) that exclude Europe and the US. This approach should also include supporting and investing in projects such as the Middle Corridor that will help economic diversification and promote external investment, while seeking to constrain projects that strengthen the Russia–Iran north–south axis and enable Moscow to reshape regional trade and transport around its own agenda.
+ +Supporting the Armenia–Azerbaijan peace process, including measures to build trust and confidence to overcome the legacy of conflict, will be critical, as this agreement is central to opening the region. To play such a role, the Euro-Atlantic community will need to be more effective in balancing its approaches with Armenia and Azerbaijan. Rebuilding a political relationship with Baku, which is increasingly the regional agenda-setter, to go beyond energy cooperation will be a necessary step to balance Moscow–Baku ties. If peace can be achieved, there will also be opportunities to advance regional cooperation among the South Caucasus countries, which Russia has effectively undercut to date, and which can help to balance Moscow’s policies by strengthening regional balancing.
+ +While domestic political forces more favourable to the West may re-emerge in the countries of the South Caucasus, the geopolitical and geo-economic context in the region militates against the Euro-Atlantic integration model regaining traction, with its interdependent security, normative and economic elements. Russia has begun to adapt its approach to the South Caucasus as the region undergoes change, and so must the West. Support for democracy and human rights should be pursued, where realistic, but its prioritisation will need to be balanced with the geopolitical imperative of building relationships to counter Russia and its major allies.
+ +Enhancing coordination with Turkey on regional issues should be a priority. Ankara is continuing to strengthen its South Caucasus interests and engagement as part of a broader strategy reaching to Central Asia and across the Black Sea. An opening of the South Caucasus would inevitably see an even greater Turkish presence. As a NATO member, Turkey is uniquely placed to strengthen regional security that aligns with the wider interests of the Euro-Atlantic community, if common cause can be promoted.
+ +Without a readiness to adapt, the Euro-Atlantic community is likely to face a growing regional marginalisation and the prospect that Russia will be able to reposition itself, while the countries of the South Caucasus are likely to be drawn increasingly into regional and international groupings that exclude the US and Europe. To challenge Russia effectively and to rebuild regional influence, the Euro-Atlantic community will need to recalibrate its policies and move beyond approaches that have lost the ability to shape regional developments effectively.
+ +This will involve difficult trade-offs, including working with non-democratic regimes. It will also mean being ready to acknowledge that the South Caucasus is unlikely to be part of a wider Europe, and so should be approached through the sort of foreign and security policy frameworks that are applied to other such parts of the world, rather than through integration. While such a shift will be challenging, Russia is at a uniquely vulnerable moment in the South Caucasus as the region undergoes far-reaching change. Although Russia is already active in repairing its position, the Euro-Atlantic community nevertheless has an opportunity to help facilitate a regional realignment that could substantially constrain Moscow.

+ +Export controls on semiconductor manufacturing equipment (SME) represent a key focus of ongoing U.S. government efforts to “choke off” China’s access to leading-edge semiconductors. The United States, along with allies such as the Netherlands and Japan, is a global leader in production and R&D for chipmaking tools. By imposing uniquely broad and unilateral controls on U.S. toolmakers’ access to the Chinese market, however, the U.S. government has turbocharged Chinese efforts to wean off all U.S. SME due to growing concerns about the reliability and trustworthiness of U.S. companies. In this way, expanding U.S. trade restrictions are facilitating the “design-out” of U.S. toolmakers in Chinese semiconductor supply chains in favor of domestic and third-country (i.e., non-U.S. and non-Chinese) companies. This growing trend in China’s market, the world’s largest for semiconductor manufacturing, threatens the long-term leadership of the United States in SME by diverting revenue (and R&D investment) away from U.S. industry. As a result, current U.S. export controls risk jeopardizing the economic and national security of the United States by hindering U.S. companies’ market share and accelerating China’s relative technological gains. This report, the second in a series on U.S. semiconductor export controls, outlines the importance of SME to chip markets, key types of tools being designed-out, and the rapid growth of Chinese toolmakers. It also evaluates how toolmakers based in third countries have leveraged U.S. unilateral controls to win new business with Chinese customers. The report argues that the United States should limit further unilateral controls on SME sales and consider new incentives for allies to create multilateral export regimes, which could mitigate some of the negative impacts of current controls on U.S. companies.
+ +With geopolitical competition intensifying, U.S. economic security policy has undergone significant changes. Primarily, the United States has expanded economic security measures to take new defensive actions around critical and emerging technologies (CETs). Such efforts center on denying China access to key foundational technologies — particularly advanced semiconductors that support dual-use applications such as artificial intelligence (AI).
+ +The administrations of Presidents Donald Trump and Joe Biden have expanded economic security measures regarding China’s access to CETs. Export controls are an increasingly common tool in U.S. economic security efforts, and National Security Advisor Jake Sullivan has called them a “new strategic asset in the U.S. and allied toolkit.” Under the Biden administration, the federal government has implemented two major rounds of semiconductor export controls, one in October 2022 and a second in October 2023. Additional controls may be forthcoming as the United States aims to use trade restrictions to deny China access to leading-edge semiconductors, thus limiting China’s ability to develop military and dual-use technologies such as advanced AI systems.
+ +The potential benefits of such a strategy to economic and national security are obvious. They include maintaining technological superiority for modern military capabilities and intelligence gathering. Washington sees clear, legitimate risks associated with the proliferation of highly advanced semiconductors among its adversaries. A sensible U.S. export control policy focused on preserving technological superiority is a measured response.
+ +Export controls, however, are a double-edged sword. When a nation decides to implement controls, it effectively restricts its companies’ market share. If controls negatively affect a nation’s technological champions, policymakers may inadvertently compromise their country’s status as a long-term technology leader. The loss in sales decreases these tech champions’ revenue and, in some cases, redirects it to foreign competitors, potentially reducing future investments in innovation for key U.S. firms.
+ +Washington sees clear, legitimate risks associated with the proliferation of highly advanced semiconductors among its adversaries. A sensible U.S. export control policy focused on preserving technological superiority is a measured response.
If the relative costs imposed on China’s technological progression and the corresponding benefits to U.S. national security outweigh the costs to U.S. industry and innovation, then Washington may well view these impacts as a necessary price. However, China’s semiconductor ecosystem — through its own strategies and through government support — has managed to undermine the effectiveness of many of the controls meant to keep Chinese firms behind their Western counterparts. For one, Chinese companies have found ways to access U.S. technology by circumventing controls. These efforts have been widely written about and include using overseas shell companies to purchase controlled products, as well as leveraging domestic technology trading networks to redirect technology via firms that are exempt from controls.
+ +Beyond circumvention efforts, U.S. export controls have helped facilitate a farther-reaching unintended consequence: China has set its domestic semiconductor ecosystem on a path toward removing U.S. technology altogether. Chinese government and commercial actors have deployed two key long-term strategies to create ex-U.S. supply chains for semiconductor technologies across the value chain. These strategies, which represent the focus of this series of papers by the CSIS Economics Program and Scholl Chair in International Business, include the following:
+ +Design-out: supplanting existing U.S. and allied semiconductor technologies with comparable technologies, from either
+ +a. Chinese firms; or
+ +b. third-country (non-U.S. and non-Chinese) firms
+Design-around: developing new technologies that do away with an entire category of controlled technology in the semiconductor supply chain
+As discussed in the Economics Program and Scholl Chair in International Business’s introductory report in this series, which covers advanced packaging, China is rapidly accelerating the design-out of U.S. technologies from semiconductor supply chains in response to existing — and in anticipation of future — U.S. export controls. It has pursued this goal, in part, by increasingly adopting domestic firms’ technologies. China’s semiconductor industry has rapidly pivoted toward made-in-China technology over the last few years, facilitated by expanded government investment and other incentives, as well as preferential procurement practices by Chinese semiconductor companies.
+ +There is also evidence of increased Chinese adoption of third-country suppliers within semiconductor supply chains. For instance, competitors from Japan, the Netherlands, Taiwan, Israel, and South Korea have increasingly leveraged China’s chip market as a growth engine, winning new Chinese customers and increasing existing customers’ wallet share as the impacts of U.S. export controls constrain the competitiveness of U.S. companies. This third-country design-out threat potentially shifts semiconductor industry leadership toward foreign competitors, some of whom offer China the very technologies U.S. companies are barred from selling.
+ +In addition, China is looking to design around U.S. export controls — in other words, innovate to achieve advanced semiconductor capabilities using approaches not modeled on U.S. technologies. Importantly, this trend means China is beginning to innovate rather than copy foreign technology in the chip industry. As discussed in the packaging report, a shift away from a “fast-follower” approach toward a more innovative approach would represent a key change in U.S.-China technological competition — one that potentially threatens long-term U.S. innovation leadership.
+ +It would be one thing if China’s design-out and design-around strategies affected only leading-edge semiconductor technologies, which are the primary targets of U.S. export controls. However, China’s pivot away from U.S. technology has affected not only the leading edge but also foundational, or “trailing-edge,” semiconductor technologies. Chinese and third-country firms want to avoid dealing with the high regulatory and financial burdens of U.S. export controls, which are complex, stricter than other nations’ in coverage and enforcement, and fast evolving. As a result, Chinese and foreign companies selling to the Chinese market are newly incentivized to avoid using U.S. technology where possible. Additionally, the ambiguity of the controls means that firms may opt to overcomply with export regulations and avoid selling or purchasing U.S. technologies — even if the products technically fall outside of the controls — for fear of dealing with costly litigation.
+ +The United States, for its part, looks to press forward with stricter controls. This threat of stricter controls, in turn, encourages China to design out and design around other U.S. technologies to hedge against future regulations. In this way, tightening unilateral U.S. export controls is having a ripple effect across the Chinese — and global — semiconductor ecosystem, threatening to undermine U.S. leadership and leverage in the sector.
+ +Semiconductor Manufacturing Equipment
+ +This paper focuses on China’s design-out and design-around strategies related to semiconductor manufacturing equipment (SME) — the machines critical to making chips. China’s access to such equipment has become increasingly important to its national semiconductor ambitions as expanding U.S. and allied export controls limit Chinese access to leading global chip manufacturers such as Taiwan Semiconductor Manufacturing Company (TSMC), Samsung, and Intel.
+ +SME is a strong example of the design-out issue. Chinese companies are increasingly replacing U.S. producers one-to-one in Chinese semiconductor manufacturing facilities, or fabs. As procurement practices in Chinese fabs shift toward an anywhere-but-the-United-States approach, SME sales are also shifting toward third-country toolmakers.
+ +SME is a strong example of the design-out issue. Chinese companies are increasingly replacing U.S. producers one-to-one in Chinese semiconductor manufacturing facilities, or fabs.
The United States would benefit economically and strategically from continuing to sell some SME technology to China. These benefits do not apply to technologies that are highly specific to advanced dual-use technology and cannot be acquired elsewhere or rapidly developed domestically. For example, ASML’s sales of extreme ultraviolet (EUV) lithography provide a choke point for Chinese technological advancement into fabrication processes like 3 nanometers (nm) and is a prime example of the power of export controls. But for less niche and non-sole-sourced tools, unilateral and broad export controls risk U.S. technology champions losing out on revenue while China maintains its access to the same technology, either via industry indigenization efforts or shifting purchases to third countries.
+ +This paper explores why SME is important to semiconductor technological innovation, what types of U.S. SME are facing design-out and design-around risks, and what implications those risks carry for U.S. economic and national security.
+ +Making semiconductors is impossible without a wide array of specialized, highly advanced machinery. Each manufacturing plant, or fab, contains an average of 1,200 multi-million-dollar tools — all of which are critical to chip production. This group of tools transforms a thin piece of crystalline silicon or other semiconducting material into a fabricated wafer containing billions — if not trillions — of nanometric transistors precisely etched onto a tiny surface area (often just 300 millimeters). Capital expenditures (CapEx) on SME constitute an estimated 75 percent of total CapEx on fab construction, and some tools reach the size of a double-decker bus, costing upward of $150 million.
+ +Semiconductor fabrication, both for leading-edge process nodes and mature chip technologies, is one of the most complex manufacturing processes on the planet — in large part due to the machinery required. For instance, ASML’s EUV lithography devices have been called “the most complicated machine humans have built.” As a result, advancements in SME technology have historically represented a key driver of semiconductor industry innovation. High-quality SME is also critical to the economics of scaled production, as any imprecision in a finished chip’s structure or composition can affect performance and reduce a fab’s production yield. All this means that a fab’s access to tools is a leading determinant of how competitive its technology is on a global scale.
+ +SME is often divided into front-end equipment used in wafer fabrication and processing, such as lithography, etch, deposition, and cleaning, and back-end equipment used for assembly, packaging, dicing, bonding, and testing. Because the advanced packaging brief covers assembly and packaging equipment, this brief focuses on fabrication and test equipment in evaluating design-out and design-around risks.
+ +Four types of SME across front-end and back-end equipment are under significant threat of design-out: (1) deposition, (2) etching, (3) process control, and (4) testing. While discussions of the semiconductor supply chain often group testing with assembly and packaging, the authors include testing within SME here for two reasons: First, testing plays a key role in front-end wafer fabrication (as well as in back-end processes like assembly and packaging), as it takes place continually throughout the production life cycle. Second, the design-out and design-around dynamics of testing equipment are more like those of chipmaking tools rather than those of assembly or packaging technologies. As in the areas of etching, deposition, and process control, the United States is home to leading competitors in testing equipment, which are facing design-out risks from foreign manufacturers. For these reasons, testing is included as part of SME in this report.
+ +The following section introduces each category of SME as well as the key U.S. and global players associated with it. The primary takeaway is that U.S. manufacturers, alongside competitors primarily from U.S.-allied countries such as Japan and the Netherlands, have historically held leading shares of global equipment markets — particularly for chipmaking technologies at the leading edge. This leadership underscores the high stakes of any shift in global market share because of U.S. export controls. U.S. companies have much revenue and technological leadership to lose to new Chinese companies — as well as Dutch, Japanese, Israeli, German, and other foreign firms, many of which are well positioned in equipment markets to grab a share of the U.S. market.
+ +The deposition process involves specialized tools depositing thin films of conducting, isolating, or semiconducting materials on the wafer. Deposition takes place throughout the fabrication stage and often occurs in multiple sequential iterations along with processes such as photolithography and etching. It plays a key role in enabling miniaturization in semiconductors, as it can create protective barriers to prevent atomic-level interference. Deposition can also help strengthen or weaken an electric field and connect transistors with other devices and power sources.
+ +There are various types of deposition used in wafer fabrication. U.S. companies such as Lam, Applied Materials, Plasma-Therm, and Veeco are key players across most types of deposition tools. The two areas discussed in depth here are epitaxy and atomic layer deposition, given their potential for design-out by Chinese supply chains.
+ +Epitaxy — also known as “epi” — involves depositing a near-perfect crystalline layer directly on top of the wafer substrate. Epitaxy growth typically occurs during the beginning of the wafer fabrication process, following wafer polishing and preceding the sequences of lithography, etching, and other deposition processes. Adding an epitaxial layer helps fabs better control doping wafers with impurities and can introduce a different material than that used in wafer “bulk” materials. As a result, epitaxy facilitates more effective electron transmission, a key goal in advanced chipmaking.
+ +Epitaxy innovation plays an important role in the ongoing evolution of both chip fabrication and advanced packaging. Epitaxy is important to nonclassical wafer substrates (i.e., nonsilicon) such as gallium arsenide (GaAs), gallium nitride (GaN), and silicon carbide (SiC), which play a key role in critical technologies such as aerospace and defense applications and electric vehicles. An emerging technology within the field of epitaxy is remote epitaxy. Remote epitaxy is the growth of a thin epitaxial layer that is aligned — but not in contact — with the substrate. This technique has a plethora of applications in advanced packaging, particularly three-dimensional (3D) packaging designs, in which multiple chips are stacked to enhance bandwidth while reducing power consumption and footprint.
+ +The epitaxy equipment market includes tools used for metal-organic chemical vapor deposition, high-temperature chemical vapor deposition, and molecular beam epitaxy. Leading suppliers are based in Germany, the United States, and Japan — as well as China. Key companies in terms of 2020 market share include Germany’s Aixtron, the United States’ Veeco, China’s Advanced Micro-Fabrication Equipment Inc., China (AMEC), and Japan’s Tokyo Electron (TEL).
+ +Atomic layer deposition (ALD) is an advanced type of chemical vapor deposition (CVD) that adds layers consisting of a single atom of thickness onto a wafer. It is key to leading-edge chip designs due to the importance of controlling layer thickness and composition in fabricating advanced chips, whose features are small enough that the industry is running up against the physical limits of miniaturization. There are two key types of ALD: thermal ALD and plasma-enhanced ALD (PEALD). Whereas the former relies solely on chemical precursors to deposit the atomic layer, PEALD uses plasma to provide reaction energy for the process, enabling greater control over film characteristics.
+ +Netherlands-based ASM is the leader in ALD, particularly PEALD, holding above 50 percent of the market, according to investor materials. Additional key suppliers include Japan’s Kokusai, TEL, and Optorun, as well as the United States’ Lam Research. As of 2020, China’s Naura had a “negligible” share.
+ +The etching process involves carving a precise pattern onto the wafer by selectively removing layers of material using either liquid or gas chemicals. Etching takes the pattern created during photolithography — during which a light selectively removes parts of a photoresist coating based on a photomask design — and applies this pattern permanently to the material layer below. Etching occurs multiple times in fabrication and creates a complex pattern of cavities where the thin film layer has been removed.
+ +There are two main types of etching tools: dry and wet. Dry etching tools use gases to engrave the wafer and are necessary to create the circuitry on leading-edge chips. Atomic layer etching tools are particularly important for advanced process node production due to their greater control and precision. Wet etching, which uses liquid chemicals to engrave the wafer, is less common than dry etching for advanced process nodes due to the challenges of creating complex structures. However, it is cheaper and less risky, making it commonly used to clean wafers. Because etching also plays a key role in mature chip technologies, both dry and wet etching tools are critical to semiconductor manufacturing.
+ +The United States and Japan are the world’s leading suppliers of etching equipment, followed by China and South Korea. Lam Research, Applied Materials, and KLA all have strong shares in global dry and wet etching markets. Japan’s TEL, Hitachi, and Screen are other notable players. South Korea-based SEMES represents a growing wet etching player. Finally, in China, AMEC, Naura, and Kingsemi are notable small providers of etching tools.
+ +Process control refers to using monitoring tools in semiconductor manufacturing to ensure quality control. It takes place concurrently with other stages of fabrication and involves metrics like the purity of wafer materials, transistor dimensions, and chip conductivity. As chip dimensions get smaller, variations at the molecular level represent a larger share of an integrated circuit’s dimensions, making process control increasingly important in fabrication. Ongoing industry shifts, like the switch from single patterning to multiple patterning and from planar to 3D transistors, mean that variations increasingly come from the material quality or the deposition process, calling for more advanced control tools.
+ +Process control is important to both advanced and mature node production, as it has a key impact on yield. Wafer production yield, or the percentage of individual chips (dies) per wafer that make it through the final probe testing stage, is a critical metric for fabs due to their high per-unit operating costs. Process control technology helps enable a higher yield, thus improving profitability by minimizing wasted output.
+ +Key types of semiconductor process control technologies include photomask inspection and repair tools, process monitoring equipment, wafer inspection equipment, and wafer-level inspection packaging tools. U.S. companies hold strong market share across all key types of tools. Notable U.S. players include Applied Materials, KLA, Keithley Instruments, Keysight Technologies, Onto Innovation, Nanotronics, and Thermo Fisher. Japan and Germany are home to most leading competitors, such as Lasertec, Rigaku, and Screen in Japan and Zeiss and Bruker in Germany. Chinese players are smaller and include Shanghai Micro Electronics Equipment (SMEE), Jingce, and Raintree.
+ +While various players compete across the entire process control ecosystem, individual markets are often highly concentrated among a few players. For instance, the market for wafer-level packaging inspection tools is dominated by one U.S. and one Israeli firm. As a result, the impact of export controls on a single company’s positioning can have a significant effect on global market shares.
+ +Semiconductor testing occurs at multiple stages during fabrication and packaging, helping ensure defective chips do not make it into final packages. Chips go through up to six stages of testing: (1) wafer acceptance, (2) wafer sort, (3) wafer-level burn-in, (4) package test, (5) burn-in test, and (6) testing at the system level. Testing equipment has taken on increased importance and industry value as the cost of testing devices and the potential losses associated with manufacturing defective dice have risen in response to advances in chip design and applications such as advanced graphics processing units, which are commonly used to train AI models.
+ +Key types of semiconductor testing tools include burn-in test equipment, handlers and probes, linear and discrete testing tools, and system-on-a-chip testing equipment. Japanese and U.S. firms hold leading market shares in different parts of the industry. Notable Japanese companies include Advantest, Tesec, and Accretech. U.S. players include Teradyne, National Instruments, and Cohu. South Korean firms such as UniTest and DI Corporation are also key participants. Chinese capabilities have historically been more limited.
+ +The Commerce Department’s October 7, 2022, rules, implemented under the Export Administration Regulations (EAR), require licensing of U.S. equipment and persons involved in certain types of chip manufacturing. Affected technologies include equipment used in the production of “logic chips with non-planar transistor architectures . . . of 16nm or 14nm, or below; DRAM memory chips of 18nm half-pitch or less; [and] NAND flash memory chips with 128 layers or more.” The regulation’s October 2023 updates tighten controls to include some older technologies, such as immersion deep ultraviolet (DUV) lithography.
+ +Products newly subject to the EAR include both items in the United States and “all U.S. origin items wherever located.” This inclusion means that U.S.-based multinational companies producing SME (not to mention other semiconductor technologies) cannot avoid the controls when selling to China, even when relying on factories abroad.
+ +For companies based outside the United States, determining whether the EAR applies is more complex. Foreign-made items may be subject to the EAR in two ways: (1) falling under a U.S. foreign direct product rule (FDPR) or (2) exceeding the de minimis threshold of “controlled” U.S.-origin content. Ostensibly, both rules apply the U.S. controls extraterritorially, leveraging the frequent presence of U.S. technology in third-country products.
+ +++ ++
Foreign Direct Product Rules
FDPRs apply the EAR to foreign-made items if they are the “direct product” of certain types of U.S.-origin equipment, software, or other technology, and are destined for designated countries. Specifically, FDPRs empower the Bureau of Industry and Security (BIS) to require licenses for exports of certain foreign-made products if listed U.S. technology was directly used to produce them or produce key parts of the plants that were used to manufacture the products, such as a tool or a piece of software — even if a controlled U.S. component or system does not appear in the product.
Three FDPRs limit Chinese access to semiconductor technologies: the Entity List (EL), Advanced Computing, and Supercomputer FDPRs. These FDPRs differ in terms of the products, companies, and countries that they cover. The EL FDPR, introduced in May 2020 by the Trump administration, applies U.S. export controls to products destined for hundreds of Chinese (and other foreign) companies and their subsidiaries. These restrictions vary based on the products involved as well as the type of EL classification applicable to the purchaser company. Their reach has continued to grow as the U.S. Department of Commerce has added Chinese firms to the EL. The Advanced Computing FDPR applies the EAR to a narrower range of products meeting certain performance parameters and based on the destination country rather than the destination company. Originally aimed at China, the Advanced Computing FDPR has expanded the list of destination countries to include the countries China likely uses to avoid controls, such as Kazakhstan and Mongolia. Finally, the Supercomputer FDPR applies a country and end-use scope to encompass any items subject to the EAR that are used to produce supercomputers, which are defined based on compute capacity and system dimensions.
The FDPRs and de minimis rules aim to limit the ability of third-country suppliers (who face less strict export controls from their governments) to replace U.S. suppliers in Chinese markets. However, their current efficacy in this regard is questionable. Multiple U.S. SME companies told CSIS that these restrictions are not stopping foreign toolmakers from replacing them in Chinese fabs, a complaint that has also been raised to U.S. officials. While public evidence supporting this trend remains limited, a New York Federal Reserve study from April 2024 on the impacts of U.S. semiconductor export controls showed that non-U.S. firms that sell to Chinese semiconductor companies experienced “higher revenues and profitability . . . following the inclusion of the Chinese targets in the U.S. export control lists.”
+ +++ ++
De Minimis Rules
De minimis rules apply the EAR based on the inclusion of U.S.-origin controlled inputs in foreign-exported goods destined for specific countries. Notably, unlike the FDPRs, use of de minimis rules requires that the exported goods directly contain products produced in the United States that fall under the EAR. This differs from the FDPR’s broader threshold of goods being the “direct product” of certain U.S.-origin technologies or inputs (that do not need to be included in the actual goods being shipped). In cases where the shipment of the U.S. inputs to the final country destination by themselves (i.e., when not incorporated into a final product) would require a license, a de minimis calculation is necessary for the foreign export of the product that contains the inputs. Depending on the type of product and country destination, different de minimis thresholds — or the minimum percentage of U.S.-origin controlled items as a share of “fair market value” at which the EAR applies (typically 10 or 25 percent) — are relevant to the specific good. If the good exceeds the relevant de minimis threshold, an export waiver is required, pursuant to the EAR. For some products (e.g., certain lithography tools), a zero percent de minimis threshold applies, meaning that inclusion of any U.S.-origin controlled input automatically applies the EAR.
Notably, the United States has been relatively hesitant to apply the FDPR to foreign exports of semiconductor technology due to the rule’s negative perception among U.S. allies. Allied governments and companies have sharply criticized the FDPR as an overreach of U.S. export control authority. During recent discussions in which the United States threatened to expand application of the FDPR, foreign governments reportedly said they would not cooperate with enforcement of this application, potentially threatening FDPR expansion. Although the U.S. government is reportedly preparing an expansion to the FDPR and EL that would increase restrictions on foreign exports, a Reuters report indicated that category A:5 countries — which include Japan, the Netherlands, and South Korea — would be exempt from the expanded FDPR. The exclusion of countries home to leading toolmakers like ASML and Tokyo Electron belies the U.S. government’s continued hesitation to use the FDPR on key allies in the semiconductor supply chain.
+ +Enforcement of extraterritorial applications of the EAR is also a challenge. For semiconductor controls, enforcement challenges are exacerbated by needing to know the node process for which the technology is used, in order to determine whether the extraterritorial rules apply. As an example, SME used in the production of “advanced-node integrated circuits” does not have a de minimis level in terms of U.S. content, whereas SME for less mature chipmaking does. For shipments of finished chips, the node process is self-evident, based on the exported product itself. However, for SME and other inputs, the type of process node manufactured using the product may be less transparent to suppliers. For instance, the same types of etch equipment may be used in a wide range of process nodes, a practice known in the industry as “CapEx recycling.” Therefore, suppliers could unintentionally sell some tools used for advanced nodes to Chinese customers, as these customers can lie about the process node they are using the tools for. Additionally, the burden falls on the company to determine whether the foreign-made item is subject to the EAR, further challenging enforcement.
+ +Interestingly, the New York Federal Reserve study described an increase in revenues for third-country firms despite including firms ostensibly subject to the extraterritorial restrictions (via FDPR or de minimis) in its data set. The authors admitted that this had the potential to bias “estimates towards finding a decline in revenues by non-U.S. firms that sell to Chinese targets.”
+ +These findings suggest that the United States is applying the EAR less restrictively to third-country firms than U.S. firms, even where the FDPR or de minimis restrictions are meant to apply — another indication of potential challenges facing enforcement.
+ +Even when fully enforced, FDPR and de minimis requirements are potentially avoidable by removing U.S. technologies from supply chains. Industry participants reported to CSIS that the EAR is incentivizing foreign toolmakers to minimize the use of U.S. technologies, services, and personnel in supply chains to avoid restricted trade with China. For example, one individual noted that a Japanese toolmaker was removing U.S. components from its supply chains and publicizing its products as outside U.S. EAR authority — a practice the individual suggested was widespread across SME markets globally. Reports of these supply chain shifts suggest that, at least for some third-country toolmakers, reliance on U.S. technology is low enough to make avoiding the existing FDPR and de minimis thresholds possible.
+ +In 2023, the Netherlands and Japan adopted their own export controls following U.S. diplomatic efforts. However, these restrictions remain less stringent than U.S. controls in terms of end use and servicing personnel, giving Japanese and Dutch companies greater ability to sell to Chinese customers and provide on-the-ground support. Additionally, other key supplier countries such as South Korea, Israel, and Germany have not adopted similar export controls. Under the existing set of international export controls, foreign toolmakers continue to face significantly weaker restrictions on access to the Chinese market than U.S. companies.
+ +A final risk of the current EAR in terms of creating unequal market access for U.S. and foreign companies is overcompliance. As one public commentator argued to BIS,
+ +++ +The October 7 IFR is so complex that only a small group of people with significant experience in the EAR and semiconductors can fully understand the rulemaking . . . Many small and medium enterprises, or even large foreign multinationals, not highly versed in these details will either not know if they are following the rule, or out of an abundance of caution, “over-comply” by restricting legitimate exports and trade not otherwise subject to these rules.
+
While the October 2023 update simplifies calculations and identifies flags to help companies determine compliance, challenges remain in terms of understanding the breadth of the restrictions, which are highly technical and continually evolving.
+ +In other words, the EAR’s complexity and ambiguity risk encouraging U.S. toolmakers to pull back from Chinese markets — even in places where they are not legally required to do so. For instance, the previously mentioned New York Federal Reserve study also showed that U.S. firms were more likely to terminate relations with Chinese customers following the export controls, even with those not directly targeted by the controls, and less likely to form new Chinese customer relationships — potentially due to concerns about unintentionally violating restrictions. This risk of overcompliance also makes it more likely that third-country companies will design out U.S. companies, facilities, and personnel, even in areas not covered by export controls, to ensure they avoid the regulations.
+ +As U.S. economic and national security policy has become more stringent, Chinese businesses and policymakers have accelerated the semiconductor industry’s shift away from U.S. inputs. China’s SME industry historically has failed to achieve technological parity with foreign toolmakers due to factors such as the smaller size of its companies and, as a result, its reduced capacity to invest in research and development (R&D). Instead of buying domestic, leading Chinese chipmakers such as Semiconductor Manufacturing International Corporation (SMIC), Hua Hong Semiconductor, and Yangtze Memory Technologies (YMTC) have sought out the most advanced chipmaking technology available — which is often of U.S. origin. For instance, Applied Materials, KLA, and Lam Research all held large market shares in Chinese chip markets as of 2022. That same year, China’s SME localization rate (the share of tools produced domestically) was 21 percent. A 2021 report by Georgetown’s Center for Security and Emerging Technology estimated a localization rate of just 8 percent.
+ +However, strong evidence suggests that China’s procurement approach has shifted since late 2022, with the removal of U.S. technology emerging as a primary industry objective. In 2023, China’s SME localization rate nearly doubled year over year to reach 40 percent. A South China Morning Post article recently reported that the “unwritten rule” for Chinese fabs was 70 percent self-sufficiency (made in China) in SME and that firms were achieving “significant progress” for key types of chipmaking equipment, with the exceptions of lithography, ion implantation, and inspection and metrology (parts of process control).
+ +This design-out trend results from increasing top-down pressure from government officials and growing bottom-up commercial incentives for Chinese companies to minimize exposure to present — and future — U.S. regulatory actions. In the SME space, China’s semiconductor industry is pursuing design-out through two main approaches: (1) increased procurement from and investment in Chinese toolmakers and (2) replacement of U.S. SME technology with products from third-country firms.
+ +An April 2024 quote in the Financial Times by a YMTC investor neatly summarizes China’s general design-out strategy for SME:
+ +++ +If Chinese companies have equipment that can be used, [YMTC] will use it. If not, it will see if countries other than the US can sell to it. . . . If that doesn’t work, YMTC will develop it together with the supplier.
+
In China, the export controls from October 7, 2022, accelerated a joint government-industry effort to build a domestic semiconductor supply chain for chipmaking equipment. De-Americanizing Chinese semiconductor supply chains has been a Chinese objective for decades. However, Chinese firms frequently ignored this top-down policy goal and sourced large shares of chipmaking equipment from abroad, including from U.S.-based companies.
+ +The Trump administration’s April 2018 imposition of sanctions and export controls on ZTE represented a major turning point in pushing China to take steps toward reducing U.S. reliance, particularly for semiconductors. These efforts went into overdrive following the October 7 export controls, which created immediate existential challenges for the Chinese semiconductor industry’s access to key technologies. As a result, the controls catalyzed a coordinated response by both government and private sector entities. Central, provincial, and local government entities — as well as chipmaking firms such as Huawei, SMIC, YMTC, Hua Hong, and others — have rapidly expanded efforts to replace U.S. chipmaking technology with technology from Chinese suppliers. Nowhere in the industry has this shift been clearer than in SME.
+ +Top-down government efforts focus on putting pressure on domestic chipmakers to procure Chinese SME. For instance, some companies told CSIS that Chinese customers are facing mandates from government officials to buy most chipmaking equipment from an approved “white list” of domestic companies. These sourcing goals can overrule traditional business performance metrics such as yield, benefitting Chinese toolmakers even in cases where quality is lower relative to U.S. firms. China is also investing heavily in SME production and innovation, including via the $47.5 billion third phase of its so-called Big Fund and by increasing industry involvement in state-backed research.
+ +At a bottom-up commercial level, Chinese fabs increasingly see advantages to using Chinese chipmaking tools wherever possible. Chinese firms have diversified supply chains away from U.S. and other foreign suppliers to mitigate risks associated with current export controls — as well as the threat of future controls. For instance, leading foundries such as YMTC are increasingly collaborating with leading Chinese toolmakers to access replacement parts and help Chinese companies quickly develop SME technology. Chinese private investors are also increasingly investing in semiconductor companies, including toolmakers, attracted by public investment and the growing preference for Chinese suppliers.
+ +Based on publicly available data and interviews with industry participants, the CSIS Economics Program and Scholl Chair in International Business identified evidence of the design-out phenomenon taking place in at least four types of SME: (1) deposition, (2) etching, (3) process control, and (4) testing. These areas receive less attention than EUV lithography but nonetheless represent key technologies in the semiconductor manufacturing process. Notably, it is tougher to establish “choke points” using U.S. export controls for these areas than, for example, lithography tools and advanced metrology tools, meaning there are fewer obstacles to Chinese and third-country companies replacing U.S. technologies in Chinese fabs.
+ +Two chipmaking equipment companies in particular — Naura Technology Group and AMEC — have been the largest beneficiaries of increased investment and innovation in Chinese SME supply chains. These companies represent the best evidence of the design-out of U.S. companies via Chinese suppliers. Other key players include lithography developer SMEE, etching and glue developer Kingsemi, and test equipment provider Jingce. Chinese SME firms increasingly include smaller start-ups taking advantage of new openings in the domestic market, such as Shanghai-based Crystal Growth and Energy Equipment, which went public in early 2023.
+ +Table 1 summarizes key players in the Chinese SME space, their product focus areas, and historical global leaders based in the United States and its allies.
+ ++▲ Table 1: Product Portfolio of Chinese Original Equipment Manufacturer. Source: Kyriakos Petrakakos, “U.S. Semiconductor Export Controls Might Actually Give China the Edge,” The China Project, June 15, 2023.
+ +The growing revenues of Chinese toolmakers offer key evidence of the design-out phenomenon. The Chinese consultancy CINNO Research released a 2023 analysis showing that the revenues of China’s 10 largest SME companies increased by 39 percent in the first half of the year compared to the previous period in 2022. AMEC, for its part, saw a 32 percent rise in sales in 2023. Company executives identified strong demand from domestic firms as a key driver of growth. In August 2023, AMEC’s chairman and CEO announced his firm had developed a road map to replace foreign-produced tools with domestic alternatives. Naura saw its 2023 revenues increase by around 50 percent year over year. As with AMEC, reports attribute Naura’s rapid growth to China’s desire to remove U.S. inputs from the domestic semiconductor fabrication market. AMEC and Naura are no exception — a wide variety of Chinese toolmakers have seen explosive domestic sales growth in the two years since the U.S. export controls.
+ +There is also evidence of Chinese toolmakers winning market share away from U.S. companies, indicating that growing Chinese revenues are not just the result of top-line Chinese market growth. Historically, Chinese toolmakers could secure only a small share of key equipment markets, even within China. From January to August 2023, however, local manufacturers won 47 percent of all machinery equipment tenders from Chinese foundries, according to an analysis by Huatai Securities. An August 2023 article by the South China Morning Post reported that AMEC’s share of one type of etching equipment is expected to hit 60 percent “in the near future,” increasing from 24 percent in October 2022 — attributed to the fact that “once-dominant US chip equipment maker Lam Research saw its mainland sales drop sharply.” Notably, many U.S. toolmakers are still seeing increasing sales to China due to surging industry growth. However, companies told CSIS that this growth is significantly below what it would otherwise be in the absence of design-out practices.
+ +Beyond the observable increases in revenue and market share, reporting suggests that the Chinese semiconductor industry is publicly showing great enthusiasm for locally produced semiconductor tools and components. In March 2024, SEMICON China, a major semiconductor industry conference held in Shanghai, saw increased participation of domestic tool manufacturers and the notable absence of rival U.S. firms. Reuters also reported that several domestic Chinese semiconductor equipment companies leaned into marketing strategies encouraging Chinese fabs to buy local at SEMICON: “More [Chinese] manufacturing facilities are willing to use materials prescribed by Chinese firms, a trend that has certainly been accelerated by U.S. sanctions.” The report mentions that while Chinese domestic firms may produce semiconductor manufacturing tools and components of slightly lesser quality, China is quickly catching up to its foreign counterparts. Furthermore, Chinese semiconductor products are sold at significantly cheaper prices than those of rival firms in other countries.
+ +There has been significant reporting on Chinese tools replacing U.S. tools in the Chinese market. However, less attention has been paid thus far to the other strategy enabling China’s design-out: the increased substitution of tools from third countries — or countries other than the United States and China — in place of U.S. technology.
+ +While Chinese buyers are increasingly apt to buy from domestic toolmakers, China is still a large buyer of foreign-made tools. Foreign SME helps fulfill technological capabilities not yet developed in China’s market and provides a helpful blueprint for Chinese firms developing new tools. Since early 2023, Chinese fabs have gone on a shopping spree, amassing tools from both domestic and foreign suppliers. The most recent data, as of the first quarter of 2024, suggest that Chinese buying represents an unprecedented 45 percent of revenue for major Western toolmakers, nearly double the share of revenue recorded a year prior (see Figures 1 and 2). Some of this revenue is going to U.S. toolmakers. According to fiscal year 2023 financials, China still represents the largest geographic share of sales for Applied Materials, KLA, and Lam Research. In fact, the dramatic investment boom in China’s semiconductor industry and practices like equipment stocking in case of future restrictions have helped some U.S. toolmakers grow in the near term.

+ +However, there is evidence that China is increasingly redirecting business away from U.S. firms to non-U.S. foreign companies as part of its design-out strategy. CSIS Scholl Chair conversations with SME industry participants revealed reports that Chinese customers are increasingly selecting third-country toolmakers — such as firms based in Japan, Israel, South Korea, Germany, the Netherlands, and Taiwan — over U.S. companies in procurement decisions. Specifically, several U.S. toolmakers told CSIS they rapidly lost share to third-country suppliers in Chinese foundries subsequent to the export regulations, which is unsurprising in the context of explicit rhetoric by Chinese companies indicating a growing preference for third-country purchases. As the previously mentioned YMTC investor noted, the second option after sourcing from China is “countries other than the U.S.”
+ +China is increasingly redirecting business away from U.S. firms to non-U.S. foreign companies as part of its design-out strategy.
This trend, in part, reflects the unique limits the EAR places on U.S. firms compared to foreign companies. As previously discussed, companies can sell chipmaking equipment that U.S. companies — whose products are by definition “U.S. origin items” — cannot. Although the United States worked trilaterally in early 2023 to convince the Netherlands and Japan to adopt new controls on advanced chipmaking technologies, these rules do not equate to U.S. controls. Dutch and Japanese restrictions are less stringent than the EL (a regulatory concept they lack a close equivalent to) and do not list China as a country of concern, creating substantial coverage gaps. Additionally, Dutch and Japanese companies can keep personnel on site in China. This servicing ability provides a source of revenue and is a comparative advantage in SME, as toolmakers typically deploy teams of servicers within customers’ fabs.
+ +Even for technologies the EAR does not encompass, there are reports that Chinese fabs are selecting third-country suppliers over their U.S. competitors. This trend may owe, in part, to U.S. companies overcomplying for fear of unintentionally violating export controls. In the United States, companies such as Applied Materials have faced criminal investigations for alleged violations of export controls, so it is unsurprising that other firms (particularly smaller businesses) would want to avoid these risks, even at risk of overcompliance.
+ +More importantly, Chinese firms have started seeing U.S. suppliers as higher-risk options compared to third-country suppliers. Tightening U.S. export controls has created a perception in Chinese markets that U.S. suppliers are not a reliable long-term procurement solution. Chinese fabs are concerned both about the repercussions of violating existing controls — either knowingly or unknowingly — and mitigating exposure to stricter U.S. export controls in the future. This view encourages Chinese fabs to turn to third-country toolmakers — at least until domestic supply develops sufficiently to avoid buying foreign technology altogether.
+ +This shift has both contributed to and been accelerated by growing efforts by third-country suppliers to win business away from U.S. competitors in Chinese markets — sometimes leveraging the U.S. export restrictions as a competitive advantage. In certain cases, industry participants described instances of foreign suppliers explicitly advertising their non-U.S. inputs (an indication they were not subject to the EAR) to attract new Chinese buyers or highlighting regulatory risks as reasons to select them over their U.S. competitors. For instance, some third-country firms raised concerns about future U.S. restrictions as reasons for Chinese businesses to choose them over U.S. firms.
+ +Industry events like SEMICON China 2024 also demonstrate the new competitiveness of third-country firms. Whereas U.S. firms were absent, other foreign sellers were not. Japanese tool firms, according to a report, kept a strong presence at SEMICON. Per the same report, Chinese demand for certain Japanese products is still strong, as Japanese companies have been rewarded with increased orders from Chinese firms, especially for noncontrolled products enabling leading-edge production. This sales increase is apparent in Japanese trade data. Japanese exports of SME and related tools to China reached $3.32 billion in the first quarter of 2024, an 82 percent year-over-year increase. There have even been reports that Japanese industry groups are arranging trips for Chinese chipmakers to explore “core opportunities in Japan’s semiconductor equipment and materials industry,” with a focus on getting around U.S. export controls.
+ +While CSIS has identified some preliminary evidence of third-country design-out taking place, there remains a shortage of publicly available data to estimate the extent of the phenomenon — specifically, detailed data from U.S. and third-country toolmakers on market share losses and gains in China. Some industry participants noted that U.S. and foreign companies hesitate to describe design-out trends due to concerns about investor perceptions. Even so, the trend represents the important and largely overlooked impact of increasingly broad and unilateral U.S. export controls that target China.
+ +SME has fewer examples of the design-around strategy — or innovating Chinese technologies to circumvent the need for U.S. technologies — compared to advanced packaging. This is, in large part, because the United States and allied countries have a strong lead over China in manufacturing chipmaking tools, making it harder for Chinese companies to develop innovations that sidestep or “leapfrog” U.S. capabilities in the space.
+ +That said, one Chinese SME innovation bears mentioning in the context of design-around strategies. Increasingly, China is adopting new strategies to use older lithography equipment to achieve the same capabilities as EUV lithography, which represents a key chokepoint for Chinese lead-edge chip manufacturing. EUV machines — exclusively produced by the Dutch company ASML — are considered essential to the production of advanced chips, and exports to China have been highly limited since the Dutch government imposed restrictions on EUV shipments in 2019. However, in March 2024, Huawei and its chipmaking partner SiCarrier patented a technology known as self-aligned quadruple patterning (SAQP), which may allow them to produce the same chips as ASML’s EUV machines in a novel way. By using older DUV lithography equipment and additional etching to increase transistor density, China reportedly has the necessary capabilities for 5nm fabrication, an advancement beyond the 7nm process that SMIC provided for the Mate 60 Pro smartphone.
+ +Industry analysts believe China still needs EUV machines in the long run to reach 3nm capabilities — the leading edge in commercial production, as of this report, as pairing DUV with technologies like SAQP may represent a technological cul-de-sac in terms of achieving transistor density beyond 5nm. As a result, China is also investing heavily in attempts to develop EUV lithography domestically via efforts by companies such as Naura and Huawei. These attempts to develop EUV represent an additional example of Chinese toolmakers designing out U.S. and allies’ technology.
+ +The effects of U.S. export controls on the SME industry will shape the future of U.S.-China strategic competition in semiconductors. Chipmaking tools are not only a key driver of advanced semiconductor capabilities but also an industry area where the United States currently leads in market share and innovation. According to 2022 estimates by the Semiconductor Industry Association and Boston Consulting Group, U.S. value-added activity made up 47 percent of the global SME market, along with 26 percent for Japan, 18 percent for the European Union, 3 percent for South Korea, and only 3 percent for China. China is the largest importer of U.S. chipmaking tools in the world and is far from self-reliant. It is reasonable that the United States would seek to use its leverage in SME to ensure leadership over its leading strategic competitor in a key dual-use technology.
+ +However, current export controls could undermine the innovation leadership of the U.S. SME companies that created this leverage in the first place. The Trump and Biden administrations’ efforts to control advanced chip capabilities have catalyzed a transformative shift away from U.S. technology in China but have failed to stop access to many controlled technologies due to widely documented smuggling efforts such as transshipments via third countries and domestic technology trading networks. Moreover, policymakers have not reckoned with the fact that China’s domestic semiconductor ecosystem is already making large strides toward replicating technologies previously supplied by U.S. toolmakers — aside from a few technological chokepoints, most notably EUV lithography.
+ +Chinese — and to a lesser but still important extent third-country — toolmakers are poised to be the primary beneficiaries of China’s ongoing shift away from U.S. chipmaking equipment. The primary losers of this transition therefore are U.S. toolmakers, who increasingly find themselves excluded from parts of the world’s leading SME market. Importantly, the extent of this exclusion from Chinese markets is broader than that imposed by the export controls themselves due to multifaceted, interrelated trends such as Chinese companies hedging against future U.S. regulatory actions and overall declining trust in U.S. suppliers in Chinese markets.
+ +In some cases, the financial impacts of export controls on U.S. toolmakers are already visible. The best available evidence of this trend is the previously mentioned April 2024 New York Federal Reserve study, which stated that export control announcements were associated with negative impacts on market capitalization and revenues for affected U.S. companies. Specifically, export controls preceded a 2.5 percent abnormal decline in stock price and an 8.6 percent decline in revenue. Negative impacts on market capitalization have also taken place following the launch of criminal investigations related to export control violations. Shares of Applied Materials fell by as much as 8.3 percent following a November 2023 report that the company faces a criminal investigation regarding tools sold to SMIC. Shares of KLA and Lam Research also fell during the probe.
+ +The top-line growth of the Chinese market should not obscure the potential impacts of design-out on long-term U.S. SME revenues. Some U.S. toolmakers have seen growing sales to China because overall Chinese fab spending has soared in the last two years. This short-term sales growth belies the underlying dynamic: market share is increasingly shifting toward Chinese and third-country competitors even as the market as a whole grows. This trend will likely expand as Chinese firms like Naura and AMEC broaden their toolmaking capabilities. While the Chinese SME market “pie” is getting larger, the U.S. share is shrinking.
+ +This decline in market share means the ultimate losers in the current export regime are U.S. economic and national security. SME markets are capital intensive and have fast-paced product development cycles, much like their foundry and integrated device manufacturer customers in the chip fabrication world. These features mean that market leadership historically has been concentrated among a small group of multinationals who are able to invest large sums in research and development and globalized manufacturing footprints. Lost revenues and market share can therefore have significant long-term effects on the ability of toolmakers to remain competitive in the future. When U.S. SME companies are increasingly sidelined in Chinese acquisition of chipmaking technology, these same companies lose access to R&D dollars to support future innovation leadership.
+ +Diminishing share in the Chinese market for U.S. toolmakers also means the U.S. government loses data on Chinese fab investment and technological capabilities. Historically, U.S. companies selling to China have offered a source of insight into China’s semiconductor industry, particularly in terms of understanding the microelectronics capabilities available to Chinese defense and dual-use technologies. However, diverted market share to Chinese and third-country firms risks undermining this source of intelligence. The surprise release of Huawei’s Mate 60 Pro in 2023 provides just one example of how Chinese semiconductor advancements increasingly take place under the radar of U.S. intelligence. The risk of design-around innovation represents a particularly pressing concern, as increased Chinese innovation could result in novel technology advancements occurring without advanced U.S. awareness.
+ +Imposing these export controls has clear costs for U.S. economic and national security. It is therefore worth considering ways the United States can achieve the benefits of export controls while minimizing costs.
+ +China’s ongoing effort to reduce dependency on U.S. SME marks a significant change to previous Chinese industrial policy targets. Although China is still far from self-sufficient in chipmaking tools, its new trajectory represents an important step toward long-term semiconductor industry decoupling goals. Increasingly broad and unilateral export controls are creating strong political and economic incentives for Chinese fabs to design out and around U.S. firms’ technology, with important long-term implications for U.S.-China technology competition.
+ +This trend is unlikely to reverse entirely, even if the United States relaxes export controls. China has demonstrated progress in developing SME capabilities and is likely to continue down this path. While Chinese indigenization achievements to date have focused on mature processes, future progress at the leading edge is increasingly likely for Chinese toolmakers.
+ +Despite these changes, the United States can refine its export control regime to better balance national security and economic interests. A crucial step is to better understand how and where existing controls hurt U.S. companies. Conducting a survey of U.S. toolmakers through the Department of Commerce could provide valuable insights into market share shifts and competitive dynamics in global chip markets related to U.S. export controls. The survey could gather metrics like the share of Chinese tenders won by U.S. toolmakers relative to Chinese and third-country suppliers. It could also address the extent to which U.S. mature tools are being designed out, beyond the leading-edge tools that the controls target.
+ +Past semiconductor industry feedback on Department of Commerce surveys has been mixed, with concerns about confidentiality and business sensitivity. Therefore, the Department of Commerce must carefully communicate any new data collection efforts to ensure transparency and highlight the benefits for U.S. companies in shaping future export policies. If the survey provides evidence that current U.S. export controls have significant adverse impacts on U.S. toolmakers, the next step would be to consider how to mitigate these impacts. The current approach, which results in U.S. companies losing market share to Chinese and third-country competitors, is unsustainable — particularly considering how Chinese circumvention efforts arguably undercut the controls’ national security objectives.
+ +A key limitation of the existing controls is the failure of the United States to implement them multilaterally. Talks of a full trilateral agreement with the Netherlands and Japan reportedly broke down over inclusion of technologies such as memory and mature logic chips in controls on chipmaking equipment. Any unilateral U.S. export control decision would fuel a growing view in Chinese markets that U.S. semiconductor companies are uniquely risky partners for Chinese companies — even relative to firms based in U.S. allies such as Japan and the Netherlands. The more the United States moves without allied support to control Chinese technology, the more it risks making its firms uncompetitive with allies’ firms.
+ +The United States must determine how to position its national security partners — not just Japan and the Netherlands but also South Korea, Germany, Israel, Taiwan, and potentially others — on more equal footing in terms of limiting trade of semiconductor manufacturing technologies with China. This strategy could involve a combination of the following three approaches:
+ +Expand the application of FDPR and de minimis requirements within the U.S. controls to more effectively stop import substitution by third countries.
+Apply increased economic or geopolitical pressure on allied countries to expand their own export controls.
+Reduce the bounds of U.S. export controls to bring them back in line with multilateral agreements (e.g., the Wassenaar Arrangement).
+The third option, by itself, seems highly unlikely. Any loosening of U.S. trade restrictions appears prohibitively challenging given bipartisan anxieties about China, particularly during an election year. The approach also could fail to stem Chinese companies’ redirection of market share to third countries, as rolling back U.S. controls may not be enough to undo the loss of trust in U.S. firms within Chinese chip markets.
+ +The U.S. government is focused on the first two options: (1) expanding the extraterritorial reach of the U.S. EAR and (2) convincing U.S. allies to implement more closely aligned controls. Expanding the FDPR and de minimis restrictions could limit sales of third-country technologies, but doing so risks further upsetting allies and accelerating efforts to remove U.S. technology and labor from third-country supply chains. This trade-off limits the effectiveness of U.S. plans to add to FDPRs. The Biden administration is reportedly planning to expand the FDPR’s product scope and add 120 new Chinese companies to the EL, effectively widening the EL FDPR’s destination coverage. But, as previously mentioned, the rule is not expected to apply to category A:5 countries, which include the Netherlands, Japan, and South Korea, undercutting its effectiveness in limiting third-country exports of key chipmaking tools. While an expanded FDPR would affect other countries and territories involved in chip supply chains, such as Israel, Singapore, and Taiwan, the impact on SME markets would likely be limited to specific niches or stages of fabrication.
+ +The second option — greater multilateralization — is more promising. However, U.S. allies still have strong incentives not to impose restrictions that are comparable with the U.S. controls, as toolmakers are significant and influential economic actors in countries like the Netherlands, Japan, and South Korea. To get around these obstacles, U.S. regulators should consider an expanded menu of carrots and sticks. The current strategy of appealing to shared national security concerns has clearly been unsuccessful. Allied governments have reportedly been unconvinced by justifications for the controls in terms of China’s People’s Liberation Army capabilities, in part because of very different perceptions among key partners (e.g., the European Union) of the extent to which China poses (or does not pose) a national security threat. Some form of mutual benefit, such as via shared intelligence or economic opportunities, might therefore be necessary to convince allies to cooperate.
+ +Regardless of what incentives are on offer, the United States likely must loosen some restrictions to achieve multilateralization. These reductions could focus on contentious areas such as memory chip production and nodes like 14nm and 16nm, which the semiconductor industry rarely considers “advanced.” A narrower approach could better ground national security arguments for multilateralization, which resonate with allies for some technologies (e.g., tools for fabricating 7nm logic chips) more than others (e.g., tools for fabricating 128-layer NAND flash memory chips).
+ +Loosening restrictions to enable greater multilateralization could be paired with efforts to improve enforcement of existing controls and stem circumvention efforts, which continue to blunt the controls’ effectiveness at slowing China’s technology development. Combining these efforts provides one way to apply continued pressure on China’s chip industry (and reduce domestic political pushback) while mitigating some of the controls’ negative economic repercussions via greater cooperation with allies.
+ +Finally, the United States, even if it does not pursue a loosening of the existing controls, could return to a strategic mindset of the “sliding scale” approach in designing future export control policy. This shift could help signal to the Chinese market that the United States is not pursuing full-scale decoupling of its technology ecosystem from China’s and that it remains interested in doing business in technologies outside of the leading edge. This shift may be even more useful in convincing U.S. allies that U.S. companies will not be further restricted unilaterally and unpredictably from access to China’s markets, helping secure their role as trusted and reliable participants in globalized technology supply chains.
+ +Although U.S. toolmakers are key players in today’s semiconductor markets, U.S. leadership did not develop in a vacuum and is not guaranteed indefinitely. China remains a critical and growing market for semiconductor fabrication, so export restrictions may have far-reaching adverse impacts on U.S. SME companies. If there is one recurring theme in writing policy related to semiconductors, it is that details matter. The U.S. government must take care to design future semiconductor export controls in ways deeply attuned to the nuances of semiconductor competitive dynamics, where one small change often has powerful ripple effects across global supply chains. Export controls must not jeopardize the complex web of factors underlying U.S. market leadership in semiconductors. Otherwise, the controls risk undermining the advantages the United States has in its important technology competition with China.

They also have the potential to transform the UK approach to major development, production and support programmes – if government is willing to change how it approaches project financing.
+ +On 8 November, the UK government announced its continued commitment to the Global Combat Air Programme (GCAP). The announcement was likely a relief to Japan and Italy, the UK’s treaty partners in the programme. GCAP – and the Future Combat Air System (FCAS) programme of which it is a part – promises to take UK combat air and industrial capability into the sixth generation of combat jet platforms.
+ +GCAP from its inception involved a government-industry team rather than the traditional adversarial model. The GCAP announcement at the Farnborough air show in 2018 presented a team of the MoD and the RAF alongside four core companies. BAE Systems, Rolls Royce, Leonardo and MBDA – to generate a new aircraft and its weapons. This was a broader and earlier grouping than had been used in the 1980s with Eurofighter Typhoon, and a strong contrast even with recent naval practice in which the Navy first works out its requirement and only then goes to industry to find the best supplier. As Vice Admiral Paul Marshall told the House of Commons Defence Committee in 2023:
+ +++ +“When we have a programme or project in the concept phase, that is done by the Navy Command Headquarters development team. They take the concept and work out the requirements that the Navy needs to meet the threats of the future. Once those requirements are set, what normally happens is that it is passed to a delivery team to get on with the business of full design and implementation.”
+
Two lines of logic underpin the MoD’s new approach in Team Tempest. The first logic was that one purpose of the strategy was sustaining and developing UK industrial capability in the combat air domain. This capability primarily lay in four companies that had survived decades of industrial consolidation. The second logic was that the approach offered the prospect of better integrating and exploiting the expertise of government and industry: the MoD with its understanding of future threats and their nature, and industry with its knowledge of technology, engineering and manufacturing.
+ +We acknowledge that government-industry partnering in defence is not entirely new. But even the Carrier Alliance had been preceded by a formal competition between BAE Systems and Thales. The nearest thing to the partnering approach to what was first called Tempest may be the relationship between the government, Rolls Royce and other firms in the Submarine Delivery Agency on submarine nuclear reactors. Thus, the expansion of this approach beyond the immediate industrial concerns around the nuclear deterrent is new.
+ +Selecting key partners could be seen as encouraging corporate complacency, but this risk was mitigated by the readiness of the firms to invest significant sums of their own money in the early work without formal assurance of development, let alone production. The companies have not formally revealed their individual spending, but in total it has been around £800 million, compared to the government’s contribution of around £2 billion. The need to recover this funding, along with recognition that production will be shared across the three partners and that exports will be essential to sustain industrial capability long-term, is a major incentive for companies to avoid slacking.
+ +The dedication of corporate funding was feasible given more than 13 years of firm government signalling of an intention to maintain the national combat air industrial capability. This had been part of the Labour government’s Defence Industrial Strategy of 2005, which led to the Taranis uncrewed stealthy vehicle and the exploration of collaboration on an aircraft with France. The Conservatives’ 2015 Strategic Defence and Security Review stated:
+ +++ +“We will invest in the next generation of combat aircraft technology, in partnership with our defence aerospace industry and our closest allies. We are working with the US to build and support the F35 Lightning. We will work with France to develop our Unmanned Combat Air System programme, and collaborate on complex weapons.”
+
These words emerged publicly as the Future Combat Air Systems Technology Initiative and launched the commitment to joint MoD and private sector investment.
+ +GCAP is conceived both as an initially defined project in its own right (a crewed aircraft) and as a platform that will be designed to evolve and spirally develop over time
Thus, the Team Tempest model in the Combat Air Strategy emerged after years of discussions on how best to sustain UK industrial capabilities in the broad field of combat air. It was far from being a spur of the moment choice, and reflected an MoD recognition that:
+ +++ +“The UK’s ability to choose how we deliver our future requirements (including maintenance and upgrade of current systems) is dependent on maintaining access to a dynamic and innovative industrial base.”
+
The UK has participated in many collaborative aircraft projects, but a negative feature of even Typhoon was the limited authority of the government and corporate structures that were supposed to manage and deliver the project. Subsequently decision-making was often slow.
+ +With GCAP, the emphasis is on empowered structures and streamlined decision-making processes. The three governments were able to agree quickly on a treaty-based GCAP International Government Organisation with the legal and political powers needed to be able to manage the project from the customer side. Its commercial delivery structure – bringing together the top-level industrial players – is understood to be largely settled, with a formal announcement expected by the end of this year.
+ +The capacity of these bodies to make choices quickly without having to send everything back to national capitals and company headquarters will be exposed only during the operation of the project, but certainly the intention in 2024 is that the joint executive bodies should be able to proceed at pace in order to keep the project on track.
+ +Japan is a new collaborative partner for the UK, but GCAP is a key element in a strengthening of UK–Japan security relations that dates back to at least 2013. UK Typhoons exercised with Japanese counterparts in 2016, and Theresa May visited Japan as prime minister in 2017. All this was accompanied by company-to-company discussions among the key players. Thus, when the formal announcement of an Italy–Japan–UK aircraft programme was made in 2022, many political, military and industrial preparations had already been made.
+ +A further feature of GCAP is its conception as an initially defined project in its own right (a crewed aircraft), and also a platform that will be designed to evolve and spirally develop over time. There will thus be no single declaration of Full Operational Capability because the final “full” stage of the platform is unknown. Moreover, that platform is to be part of a wider and only partially defined evolving system of equipment and capabilities under the FCAS umbrella. Thus, the aim for 2035 is for a minimum viable product that can deal effectively with threats in the 2035–2040 timeframe, but which will be capable of regular, perhaps even continuous improvements.
+ +In terms of industrial motivation, spiral development offers an appealing base for the export potential of GCAP. All the companies are aware that the long-term sustainment of their combat air capabilities will not be satisfied by demand from the three core countries alone: exports will be necessary, and the UK government is clear that exporting needs to be a key element of its defence industrial strategy.
+ +There is nothing innovative about thinking of an aircraft as part of a wider system: the Spitfires and Hurricanes that were so effective in the Battle of Britain owed much of their effectiveness to the radar, communication and ground-based fighter control direction that made up the air defence system of the time. Moreover, the idea of “spiral development” is pretty much the same as the concept of “incremental acquisition” that was prominent in defence procurement earlier in the millennium. However, that idea was little implemented, in part because of customer reluctance to compromise on requirements when access to funding for future improvements was uncertain.
+ +A key consideration for how effectively spiral development can operate will be the availability of early funding to build in the key enablers of advances, not least strength, space and electric power in the platform as well the ease of upgrading software.
+ +Finally, a key enabler of affordability and speed of delivery will be digital engineering (DE). While largely a technology matter, DE also has organisational implications, not least in the form of company and governmental relationships with the Military Aviation Authority (MAA).
+ +The practice of designing aircraft in a computerised, digital environment is not new. All modern civil and military equipment is designed first on a computer using engineers’ expertise to inform how different elements will interact. Digital simulations enable a digital-twin aircraft to be operated by humans in a simulated “cockpit” and environment. Tests with a real system then evaluate how this simulation data corresponds with reality. However, as the documentary film about the competition for the F-35 contract between Lockheed Martin and Boeing illustrates, while these tests often confirmed the simulation data, some unexpected faults emerged. This was over 25 years ago. As time has passed, the computing capacity of simulations has dramatically improved, and so has the data base for generating high fidelity environments in benign and contested scenarios.
+ +This development in data quality and quantity and processing speed is especially important in the combat air sector because of the time and costs taken up by real-world testing and flying. The US’s transparency on many defence matters enables a sense of the scale of what “testing” has involved to date. This is apparent in a 2018 statement by Vice Admiral Mat Winter, F-35 Program Executive Officer:
+ +++ +“Since the first flight of AA-1 in 2006, the developmental flight test program has operated for more than 11 years mishap-free, conducting more than 9,200 sorties, accumulating over 17,000 flight hours, and executing more than 65,000 test points to verify the design, durability, software, sensors, weapons capability and performance for all three F-35 variants.”
+
The average sortie lasted less than two hours. Over the 11 years, more than 16 sorties were flown a week. These numbers give some sense of both the time and money that could be saved if development could be done largely online rather than in the air.
+ +The vision associated with DE is that a large amount of testing will be done online at great speed and low cost. Computers can operate “flights” on a 24-hours a day basis if need be. Sub-system testing, which is usually less expensive, can be done both online and on the ground. But the role of flight testing should be massively reduced, generating significant savings.
+ +All defence systems must have an approved Safety Case. In the case of aircraft, arrangements need the approval of the MoD’s safety authorities including the MAA. This suggests that safety and certification people should be involved throughout development, as opposed to being asked for cooperation late in the day (as was the case, for example, with the Ajax armoured vehicle programme).
+ +Another major impact of advanced DE is that it will enable numerous engineers to work on different aspects of the system simultaneously as simulation data on the mutually dependent components is shared, analysed and acted upon at much greater speed. As one key programme manager confirmed to us, this process – from simulation data to design alternations that result from it and from implementation to a model to re-run a simulation – would have taken months in the last significant UK combat air programme. Today, it can be done overnight, as the simulation alternates designs automatically to improve. In the case of GCAP, there is the prospect of a long working day for the humans involved, as those ending their day in Japan can be succeeded by staff in Italy and the UK.
+ +Development is far from the only area where DE could be a key enabler. The potential reach of DE is extraordinary. BAE Systems is already invested in digital manufacturing, robotic assembly, and training support for those doing skilled manual work. Additive manufacturing is a sub-element in DE, as are computer-controlled machine tools. It could thus cut manufacturing time and increase product reliability. In-service modification and spiral development would be quicker and easier with DE. Building data-collecting sensors into systems would support longer usage rates for platforms and enable condition-based maintenance rather than time- or usage-based maintenance. Many modern civil aircraft engines are already fitted with such sensors (linked to computers analysing their results). These mean that engine companies can take on profitable availability contracts.
+ +Advanced digital engineering will enable numerous engineers to work on different aspects of a system simultaneously as data on the mutually dependent components is shared, analysed and acted upon at much greater speed
DE is the clear direction of travel for much of manufacturing. For GCAP, expanding the boundaries of DE is key to holding costs down and delivering an aircraft for 2035: it could and should be rewarding but also inevitably risky. Significantly, it is a field which US defence companies, not least Boeing, Lockheed Martin and Northrop Grumman are actively exploring. Because of the hundreds of sub-contractors that will need to be captured within the GCAP DE tent, the expertise they acquire can be applied on other manufacturing projects, both military and civil. Subject to respect for companies’ intellectual property, the government could work to diffuse GCAP-origin DE experiences to other industrial sectors beyond aerospace. This could enable progress, especially in productivity growth, under the government’s industrial ambitions as laid out in its Green Paper of October 2024.
+ +However, this will require resources and skill. For instance, a highly secure information infrastructure that enables DE is pivotal. Clearly, information on GCAP’s digital twin and its performance in a countless number of combat scenarios will be highly prized, with state and perhaps corporate bodies focused on accessing it. A key to its GCAP capability is keeping that information safe. This has significant implications for the organisations that handle this data, including security clearances, establishing processes, and having the necessary IT infrastructure to handle data securely and at great speed. Skill is also an important factor. Government and industry alike will need to muster the necessary talent to maintain and develop DE capabilities. GCAP is conceptualised as an open-platform system that seeks to enable seamless integration of mission-specific FCAS capabilities from a multitude of suppliers. These suppliers must also be able to recruit the people required for the new digital working environment that they cannot grow themselves. Thus, government and industrial primes will need to produce a skill spill-over to make the FCAS system work.
+ +All this has consequences for the financial approach to GCAP. Historically, major defence development programmes start cheap and then build up. The DE element of GCAP means that significant initial costs of computing, staff recruitment and training and model development have to be incurred. Investment in a highly secure information storage, processing and communication system is needed early. What this means in UK terms is that Treasury approval for higher than usual early costs is needed. It is a matter of approving a “spend to save” strategy, which clearly involves risk. But DE could then play a pivotal role in materialising the cost reduction and increases in speed.
+ +The five areas of innovation in GCAP should be seen holistically as a transformational approach to defence acquisition:
+ +Government-industry partnering from the outset.
+Securing access to significant industrial cost contributions for the early stages.
+Bringing in a novel collaborative partner and setting up customer and industry delivery structures to facilitate timely decision-making.
+Starting from a minimum viable capability while envisaging spiral development.
+Pushing the boundaries of digital engineering to reduce the time and cost of development and production.
+This will require persistent teamworking across government departments, among multiple businesses and between government and the private sector. But each offers the prospect of lowering costs and flattening the tendency towards increased inter-generational aircraft costs first pointed out by Norman Augustine more than 40 years ago.
+ +The case for this approach rests on the simple observation that different things should be bought in different ways. There is no doubt that GCAP will require a mindset change from those in Defence Equipment & Support whose instinct is that the only way to secure value is through competitive tendering, passing as much risk as possible to the private supplier, and relying primarily on contracted commitments to assure delivery. Also, for teaming to be effective, there will be a need for government technical expertise to be available, not least on the design and meaning of digital and real-world tests. To be specific, the GCAP approach is particularly relevant for projects in which national operational independence is valued and there is little or no scope for sustained competition within the country.
+ +The elements of this approach give real hope for effective cost control: incentivising industry by securing early significant company investments, focusing government and industrial delivery structures on pace regarding decisions, defining a realistic but militarily adequate requirement from the outset and, perhaps above all, investing in DE to speed development, reduce risks and lower costs.
+ +Successive UK governments have shown that they can talk the talk on defence industrial matters, and their defence industrial partners have expressed confidence in their potential. Maintaining the momentum of GCAP will require all concerned to show that they can also walk the walk.
