Abstract:
After decades of seeking to reduce the role of nuclear weapons in international relations, the United States is now grappling with a global landscape marked by intense strategic competition and the growing salience of nuclear weapons—problems that will likely persist for years to come. Over the past year, Russia compounded its aggression in Ukraine with nuclear saber-rattling, modernizing and expanding its nuclear forces over the past decade. Furthermore, Russia’s possession of a substantial inventory of theater nuclear weapons continues to threaten regional deterrence. Meanwhile, in Asia, Beijing is pursuing an unprecedented surge in its nuclear capabilities. If current trends persist, China is projected to possess about 1,500 nuclear warheads by 2035.1 While China was once viewed as a secondary nuclear power, its substantial investment in its nuclear arsenal—including the launch of a third ballistic missile early-warning satellite in 2022 and advancements in land-based ballistic missiles, aircraft, submarines, and hypersonic missiles—positions China to become a near-equal nuclear power in the coming decade. These trends mark a historic shift. For the first time in its history, the United States must face two near-peer nuclear competitors simultaneously. At the same time, Russia’s suspension of its compliance with the New START agreement in 2023 has significantly weakened the last strategic arms control framework established in the Cold War and post-Cold War eras. This move leaves scant provisions governing the future of nuclear capabilities among the United States and its adversaries. For over half a century, Washington and Moscow negotiated to establish treaties that imposed limits on their nuclear arsenals, aiming to manage their nuclear rivalry and mitigate the risk of nuclear conflict. This process served the national security interests of both sides by curbing weapons and activities that could jeopardize deterrence, safeguarding strategic stability, offering insights into nuclear capacities, and potentially steering military competition toward less perilous avenues. However, shifts in the global security landscape have altered this calculus. The Russian Federation, much like the Soviet Union before it, has insisted that future agreements factor in the nuclear capabilities of Britain and France. On the other hand, the United States now confronts a security environment featuring two nuclear-armed adversaries—Russia and China—whose forces will potentially pose significant threats to the United States and its allies. This evolving security landscape may prompt the United States to reevaluate its assessments of its deterrence and arms control requirements. But how should the United States approach this problem?

Abstract:
Since the late 1960s, NATO has sought to balance two objectives—maintaining a strong nuclear deterrent while supporting efforts to buttress strategic stability through arms control and advance nonproliferation and disarmament through the nuclear Nonproliferation Treaty process. The success of this strategy was most evident in the dual-track strategy of deployments and negotiations that led to the signing and implementation of the Intermediate-Range Nuclear Forces (INF) Treaty in 1987. The end of the Cold War also led to substantial cuts in U.S. and Russian strategic systems. Since then, NATO Allies have regularly voiced their support for continuing to pursue these two objectives, including supporting the goal enunciated by U.S. President Barack Obama in 2009 “to seek the peace and security of a world without nuclear weapons.”1 In the last decade, however, Russia’s malign behavior has undermined NATO arms control efforts to the point that it appears traditional arms control will be effectively dead when the New START agreement—already suspended by Russia—expires in 2026. Russian’s invasion of Ukraine, its repeated nuclear saber-rattling in that conflict, and the deployment of non-strategic nuclear weapons to Belarus has also forced the alliance to look to ways to enhance its deterrence, including its nuclear deterrence. Meanwhile, the massive increase in China’s nuclear arsenal and its growing partnership with Russia, is generating additional pressure to increase U.S. nuclear forces as well as questions about the ability of the U.S. to provide extended deterrence simultaneously to Allies in Europe and Asia. Those doubts have been reinforced by political developments in the United States—and in the war in Ukraine—that have raised anxieties about a decoupling of European and U.S. deterrence and defense and led to fresh discussion of a potential “Eurodeterrent.” Meanwhile, developments in North Korea and Iran—and their increasingly close ties with Moscow—further threaten the viability of the already shaky nuclear and missile nonproliferation regimes and have eroded longstanding cooperation between Washington and Moscow to manage nuclear nonproliferation risks in third countries. In response to these developments, Allies and experts, such as the Congressional Strategic Posture Commission, have proposed various adaptations to the alliance’s nuclear posture, including to its nuclear sharing arrangements. This report examines these deterrence proposals, particularly considering how they support the alliance’s other longstanding objectives of arms control, disarmament, and nonproliferation. The paper begins with some background on US/NATO nuclear policy from the end of the Cold War to the further invasion of Ukraine in February 2022. It then delves into changes in Russian nuclear doctrine, Moscow’s nuclear behavior during the Ukraine War, and the Kremlin’s views on future arms control. The report next discusses China’s nuclear modernization and views on arms control and the reaction among NATO and Asian Allies and the international community to these changes. It then discusses potential future U.S. and NATO posture options, including those already being undertaken by NATO or proposed by the US. Congressional Strategic Posture Commission and the State Department’s International Security Advisory Board. It concludes with an analysis of the potential impact of various options on arms control, disarmament, and nonproliferation and offers some policy recommendations.

Abstract:
The Annual Estimate of the Strategic Security Environment serves as a guide for academics and practitioners in the defense community on the current challenges and opportunities in the strategic environment. This year’s publication outlines key strategic issues across the four broad themes of Regional Challenges and Opportunities, Domestic Challenges, Institutional Challenges, and Domains Impacting US Strategic Advantage. These themes represent a wide range of topics affecting national security and provide a global assessment of the strategic environment to help focus the defense community on research and publication. Strategic competition with the People’s Republic of China and the implications of Russia’s invasion of Ukraine remain dominant challenges to US national security interests across the globe. However, the evolving security environment also presents new and unconventional threats, such as cyberattacks, terrorism, transnational crime, and the implications of rapid technological advancements in fields such as artificial intelligence. At the same time, the US faces domestic and institutional challenges in the form of recruiting and retention shortfalls in the all-volunteer force, the prospect of contested logistics in large-scale combat operations, and the health of the US Defense Industrial Base. Furthermore, rapidly evolving security landscapes in the Arctic region and the space domain pose unique potential challenges to the Army’s strategic advantage.

4. Arresting Nuclear Adventurism: China, Article VI, and the NPT

Abstract:
Given the current crisis in Ukraine, it’s tempting to consider focusing on Chinese compliance with the Nuclear Nonproliferation Treaty (NPT) to be an academic indulgence. Giving into this inclination, however, would be a mistake. As dangerous as Russia currently is, China will be more threatening in the long run. As we are learning with Russia’s violation of the 1994 Budapest Memorandum, enforcing binding understandings is critical lest violators run roughshod over law and good order. This is true with Russia’s behavior in Ukraine. It is no less so with China’s nuclear weapons buildup and its repeated refusal to join in good faith negotiations to limit its nuclear weapons activities, which is required by Article VI of the NPT. This buildup and refusal clearly flies in the face of China’s legal NPT obligations. The question is what might bring Beijing back into compliance. To get the answers, NPEC held a battery of workshops last fall, followed by a week-long diplomatic simulation. The game participants included U.S., Japanese, and Australian former and current officials and staff as well as outside experts. The group concluded that Beijing is unlikely to comply willingly with the NPT anytime soon, but that U.S. and international security would still be best served by spotlighting Beijing’s nuclear adventurism and suggesting diplomatic off-ramps to arrest its nuclear buildup.

Abstract:
Over the past few years, China has displayed a wide range of advances in military capabilities and infrastructure, including its test of a hypersonic glide vehicle coupled with a fractional orbital bombardment system and evidence of new intercontinental ballistic missile silos. While China and the United States remain at political odds, there are indications that China’s strategies in space, cyberspace and nuclear domains are increasingly converging with those of the USA, as well as Russia. A key question is whether this strategic convergence is a stabilizing or destabilizing phenomenon. To answer the question, this paper explores the current state of Chinese discussions on multidomain deterrence and strategic stability, with a focus on active defence and proactive defence. It then examines how these concepts are manifesting themselves in China’s postural and technological indicators, including pre-mating of nuclear warheads to delivery platforms, expanded nuclear arsenal size, possible shifts towards launch on warning, integration of dual-capable systems, and advances in machine learning and autonomy. It concludes with a discussion of what these trends mean for future strategic stability talks.

Abstract:
This report examines the nuclear policies and postures of the United States and its three primary nuclear adversaries: China, Russia, and North Korea. It concludes that the world is entering a multipolar nuclear era, which is unprecedented, and far more complex and challenging than the Cold War. The current nuclear order has been gradually shifting over the past decade. Russia remains the United States’ only nuclear peer, but the arms control regime that constrained the superpowers’ nuclear arsenals is disintegrating. Relations between Washington and Moscow have worsened since Russia’s full-scale invasion of Ukraine and Russian President Vladimir Putin’s nuclear saber-rattling. China’s nuclear arsenal is growing in size and sophistication, potentially enabling Beijing to launch conventional attacks behind its nuclear shield. This development will shape both competition among Beijing, Washington, and Moscow and potential future military confrontations. Similarly, North Korea has a small but expanding number of deployed nuclear weapons and is improving its missile technology. In this new nuclear environment, the United States must deter two nuclear-armed great powers as well as a regional nuclear power from launching conventional and nuclear attacks on itself and its allies. As the number of nuclear-armed states grow, interactions become more complex and the risks of miscalculation and misperception increase. The ramifications of this new reality are not well understood, aside from the implication that there is a growing risk that nuclear weapons might be used. The study’s findings have five primary implications for American policy and nuclear posture. To improve strategic stability and enhance deterrence, the United States should take several courses of action.

Abstract:
This paper employs a comparative approach to provide an initial comprehensive analysis of the political interactions, contemporary nuclear policies, and military strategies and capabilities of China, Russia, and the United States in the context of the unstable international security landscape. At a time when the global arms control regime is teetering on the brink of disintegration, the authors aim to offer practical and feasible policy recommendations for remodeling the arms control regime from the Chinese and Russian perspectives. The authors stress the need to revive “traditional” arms control and advocate the search for ways to control emerging military technologies. This paper endeavors to present a two-pronged vision proposed by representatives of two major global players.

Abstract:
Dating back to the first test in 1964, the Chinese nuclear force modernization process is motivated by other nuclear powers’ modernization across the years, mostly from the United States and the Soviet Union, but also by domestic factors such as economic debates and tensions in the scientific community. China Nuclear Force Modernization and Doctrinal Change Download 0.63 Mo At first, technical difficulties and a greater investment in conventional forces prevented the development of a ‘lean and effective arsenal’. However, the end of the Cold War and better economic conditions allowed China to improve its weapons toward a greater duality and mobility, thus reflecting the first tensions between the Chinese no-first-use doctrine and its growing technical capabilities and ambitions. Nowadays, the Chinese nuclear arsenal is bigger than ever, ranking third in size amongst nuclear global powers and with an estimated 1,000 warheads in 2030. The weapons’ efficiency is also reportedly higher, aiming at a fully functioning triad. Furthermore, doctrinal debates are still ongoing, with potential consequences on arms control and risk management.

Abstract:
Armed forces in the Indo-Pacific region remain dependent on weapon systems imported from foreign suppliers. This is despite the efforts of many governments in the Indo-Pacific to implement policies that support the development of local arms industrial capabilities with the aim of increasing self-reliance. This report develops three indicators to give a score and regional ranking of self-reliance in arms production to 12 jurisdictions in the Indo-Pacific region: Australia, China, India, Indonesia, Japan, South Korea, Malaysia, Pakistan, Singapore, Taiwan, Thailand and Viet Nam. Overall, this report contributes to knowledge and debates on armament trends and military modernization in the Indo-Pacific. In a region where tensions among neighbours are rising, it further contributes to transparency with regard to levels of self-reliance in domestic arms production, allowing for an independent assessment of the region’s respective arms industries.

Abstract:
The year 2020 was characterized by the intensification of US-China confrontation and strategic competition, which had been pointed out in the Strategic Annual Report 2019, in all areas from military and security affairs as well as dominance in advanced technologies and supply chains to narratives on coronavirus responses. Amid this confrontation, the rules-based international order faced even more severe challenges; the multilateral framework established after World War II with the United Nations at its core lost its US leadership and fell into serious dysfunction. While the international community is struggling to cope with the rapidly expanding outbreak of the novel coronavirus, China has been moving to expand its influence through increasingly authoritarian and assertive domestic and international policies on the rule of law and territorial issues, as well as through economic initiatives such as the existing “Belt and Road Initiative” (BRI) and its responses to the pandemic. The confrontation with the United States is becoming more and more pronounced, and the Indo-Pacific region is turning itself into divided and contested oceans. In this transforming strategic environment, expressions of support for the vision of a rulesbased “Free and Open Indo-Pacific” (FOIP) that Japan has been promoting for the past several years, or announcements of similar visions have followed one after the other. The year 2020 also saw significant strengthening of the cooperative framework among four countries – Japan, the United States, Australia, and India (QUAD) – together with the enhancement of bilateral cooperation between countries in this group. At the same time, progress was also made in a regional cooperation framework that includes China with the signing of the Regional Comprehensive Economic Partnership (RCEP) Agreement in East Asia. The Strategic Annual Report 2020 looks back at major international developments since last year’s Report through the end of 2020, focusing on the transformation of the strategic environment in the Indo-Pacific region and the response of the international community.
