Abstract:
This report examines the intersection of China’s nuclear modernization and cross-Strait tensions, especially how they might play out during a crisis, contingency, or conflict involving China, Taiwan, and the United States. Beijing is rapidly modernizing its nuclear arsenal to make it larger and more sophisticated. Changes include an increase in warhead numbers from more than 400 today to potentially 700 by 2027 and more beyond, consolidating a nuclear triad, developing new delivery systems, and digging at least 300 new missile silos. Some factors still could constrain the growth of China’s arsenal or the policies that shape the way Chinese leaders employ it. They range from fissile material stocks to competing military spending priorities, considerations about China’s international reputation, and upholding Beijing’s claimed No First Use policy. But nearly all those constraining factors either already have weakened or could do so in the near future. China’s expanding nuclear arsenal suggests that the force will be designed to fulfill new missions. Some part of Beijing’s buildup surely is meant to bolster its second-strike retaliatory capability in the face of what China perceives as shifts in U.S. conventional and nuclear capabilities and policies. China’s long-term goal for the expansion, however, could be more ambitious and potentially even include seeking to build an arsenal on par with Washington’s and Moscow’s. Meanwhile, China continues to ramp up pressure on Taiwan using political, economic, and military tools. Beijing’s campaign could provoke more crises in the coming years. The three major roles that nuclear weapons could play for China when dealing with cross-Strait crises or conflicts are: to shield China from U.S. nuclear coercion, to threaten Chinese nuclear use to try to forestall U.S. intervention, and to conduct a limited Chinese nuclear detonation in an attempt to force U.S. and Taiwanese capitulation. The report concludes with recommendations for U.S. policymakers. It calls for carrying out U.S. nuclear modernization plans to deter China but avoiding nuclear arms racing as a strategy in itself. It recommends incorporating nuclear elements into contingency planning and scenario exercises related to Taiwan, both unilaterally and with allies and partners. The report then calls for improving Taiwan’s conventional military capabilities while maintaining a consistent U.S. policy on cross-Strait issues and ensuring Taiwan forgoes pursuing indigenous nuclear weapons. Finally, the report argues in favor of pushing forward tough-minded bilateral engagement with Beijing on strategic stability and security issues while crafting a multilateral arms control strategy that builds coalitions to incentivize China to join and impose costs on Beijing if it opts to stay outside of key agreements.

Abstract:
The United States–Republic of Korea (ROK or South Korea) alliance has entered a critical phase. In 2023, the two countries will commemorate the 70th anniversary of signing their bilateral mutual defense treaty. This year also marks the first full year under national leaders President Joe Biden and President Yoon Suk Yeol. After several challenging years in the two countries’ relationship, ties are improving. Better alliance relations have, unfortunately, coincided with a deterioration in the regional and global security environment, specifically due to threats from North Korea, China, and Russia. This report examines the U.S.-ROK alliance as it adapts to the new regional context by exploring how the United States and South Korea can sustain and deepen their relationship in three vital policy areas: coordination on China, alignment in minilateral and multilateral settings, and defense technology collaboration. Perhaps the biggest shift in alliance priorities in recent years has been the growing importance of the China challenge. During Chinese Communist Party General Secretary Xi Jinping’s decade in power, Beijing has adopted a more muscular foreign policy. Both the United States and South Korea have reshaped their approaches toward China in response. ROK concerns about China have grown as Beijing shields Pyongyang and acts aggressively elsewhere in the region, including toward Taiwan. But South Korea’s approach to China will continue to differ from that of the United States. The allies have divergent preferences regarding the speed, manner, and degree of partial decoupling with China. Moreover, South Korea’s deep trade ties with China will continue to make it vulnerable to Chinese political and economic coercion.

Abstract:
Two tectonic trends in the international security environment appear to be on a collision course. The first trend is the intensifying geopolitical rivalry between the United States and the People’s Republic of China (PRC or China). The second trend is the rapid development of artificial intelligence (AI) technologies, including for military applications. This report explores how the United States can manage strategic risks—defined as increased risks of armed conflict or the threat of nuclear war—that could be created or exacerbated by military AI in its relationship with China. It begins by providing an overview of China’s views on and policies toward AI. Beijing sees AI playing roles in both its civilian economy and the modernization of its military, the People’s Liberation Army (PLA). At home, Chinese leaders want to leverage AI to boost growth and innovation, address economic and social challenges, and secure the Chinese Communist Party’s (CCP) domestic rule. AI also plays a key role in China’s military ambitions, especially its goal to become a “world-class military” by midcentury, in part through the “intelligentization” of its forces. Intelligentization relies on integrating AI and other emerging technologies into the joint force with the goal of gaining an edge on the United States. China argues that its governance model, including its military-civil fusion policy, gives Beijing a competitive advantage over Washington. Realization of that vision, however, remains uncertain and will require China to overcome external and internal obstacles.

Abstract:
In December 2022, Japan’s government released three major strategic documents: the National Security Strategy, the National Defense Strategy, and the Defense Buildup Program. Although Japan has made incremental changes to its security policies and capabilities over the last decade, the new documents mark a notable shift in Japan’s approach to strengthening its defense. The documents reflect Tokyo’s assessment of the rising threats that could challenge Japan’s security and signal Japan’s commitment to build the military capabilities necessary to meet them. This report examines Tokyo’s defense transformation and assesses its implications for the U.S.-Japan alliance and Washington’s strategy toward the Indo-Pacific. Japan is “fundamentally reinforcing” its national security and defense policies to cope with its increasingly severe security environment. The military threats posed by China, North Korea, and Russia have been growing steadily for years but appear to be peaking simultaneously. Tensions between Japan and China have occasionally flared in the five decades since they normalized diplomatic relations. But those tensions have reached new heights since 2012, when China began to regularly contest Japan’s administration of the Senkaku/Diaoyu Islands. By August 2022, Beijing fired five ballistic missiles into Japan’s exclusive economic zone during China’s live-fire military exercises after then-U.S. House Speaker Nancy Pelosi’s visit to Taiwan. The aim of the missile launches was to signal there would be consequences for Japan if Tokyo were to intervene in a Taiwan contingency. Meanwhile, North Korea’s unprecedented rate of missile testing since 2022 and Russia’s brutal war against Ukraine have deepened Japanese concerns about the potential for the use of force in the Indo-Pacific. Japan is taking steps to improve its ability to defend itself and deter an invasion, including through changes to security funding and policy. Tokyo has announced plans to increase its defense spending by 65 percent over the next five years, acquire standoff weapons that could be used for a counterstrike mission, and adopt an “active cyber defense” posture. Japan has clarified the roles of its military, the Self-Defense Forces (SDF), and Coast Guard in the event of an attack; committed to establishing a permanent Joint Headquarters for SDF operations; and created a program for supplying partner militaries with security assistance. Effectively employing counterstrike and active cyber defense, however, will require a clearer delineation of the legal authorities for their use as well as the overall military strategies that they would support. In addition, pressure from the Japanese public over tax hikes required to pay for the defense spending increase amid other fiscal pressures could pose a barrier to implementation. Japan plans to strengthen the SDF through boosting readiness and resilience of current forces, acquiring counterstrike and other advanced capabilities, and improving force posture and mobility. The SDF has been plagued by a chronic lack of munitions and other supplies, and most of its facilities do not meet its own standards for resilience against enemy attack. Addressing these shortfalls is essential, though these types of programs often lose out to more high-profile programs. For its counterstrike mission, Japan has announced it will buy U.S.-made Tomahawk cruise missiles. This initial purchase will provide a stopgap until Japan is able to produce its own longer-range missiles later in the decade. Japan has also announced it will pursue new capabilities in uncrewed systems, space, cyber, and artificial intelligence (AI). But fulfilling these ambitions will be challenging given some short-falls in Japan’s technology base and SDF personnel. Lastly, the SDF is grappling with how to expand its forces in Japan’s southwest islands while maintaining a sufficient presence throughout the country to deter aggression from a range of possible threats. Next, Japan’s strategy emphasizes enhancing security partnerships regionally and across the globe. Japan has recently stepped up its defense cooperation with several Indo-Pacific and European countries. With Australia, Japan is building on a 10-year effort to deepen strategic cooperation, a process that culminated in January 2022 with the completion of a Reciprocal Access Agreement. New bilateral strategic cooperation includes enhancing interoperability between the SDF and the Australian military, increasing rotational SDF training deployments to Australia, and announcing a new joint security declaration that commits to a combined response to military contingencies. Similarly, Japan has long recognized the strategic importance of India and continues to build on the Japan-India relationship through maritime security cooperation, a new joint fighter exercise, and operationalization of their Acquisition and Cross-Servicing Agreement. Japan and the Philippines are also expanding their defense ties through humanitarian assistance and disaster relief training exercises and an important emerging trilateral security relationship with the United States. Over the past year, Japan and South Korea have made significant strides to repair relations since the latest downturn that began in 2018. This will be an incremental process, but there has been progress in the form of leader-level summits and ministerial dialogues, plans to cooperate on sharing data about North Korean missiles, and new trilateral ballistic missile and anti-submarine drills with the United States. Japan also is building defense connections and relationships with European nations. It is pursuing the development of a sixth-generation fighter jet with the U.K. and Italy and, particularly since the full-scale Russian invasion of Ukraine, has sought to deepen strategic ties with NATO. These comprehensive changes to Japan’s defense policies will necessarily reshape the military and security pillars of the U.S.-Japan alliance. Tokyo’s acquisition of counterstrike capabilities will position Japan to potentially take on some offensive tasks, even while retaining its primarily defensive orientation. This also has implications for alliance contingency planning related to defending Japan directly as well as around Taiwan, the Korean Peninsula, and the South China Sea. However, increased joint planning will require updates to alliance command and control (C2) and information-sharing mechanisms. Additionally, given resource constraints, the alliance would be well-served to find additional opportunities for military technology sharing, codevelopment, and coproduction, such as through Japanese involvement in the second pillar of the AUKUS (Australia-United Kingdom-United States) partnership focused on cooperation on advanced capabilities and defense technology innovation. And the alliance must take steps to improve force posture and readiness, including through enhancing base resiliency and increasing munitions stockpiles. Japan’s fundamental transformation of its defense posture will mean significant changes for the U.S.-Japan alliance. The United States must adapt its approach to alliance coordination to maximize new opportunities and manage any new challenges. In this context, U.S. policymakers should: Prepare to update the alliance, while recognizing that Japan’s new defense policies will require significant time, resources, and political will to implement. Stay closely aligned with Tokyo on the threat land- scape as well as engagement with geopolitical competitors, especially China. Integrate U.S.-Japan command and control structures. Create an alliance readiness, resilience, and posture implementation task force. Deepen planning for contingencies and bolster extended deterrence. Create a road map for expanding defense technology cooperation concurrently with Japan’s implementation of specific improvements to its information security practices and infrastructure. Innovate operational concepts for uncrewed systems and counterstrike capabilities. Leverage the U.S.-Japan alliance as a hub for minilateral and multilateral security engagement. Build U.S.-Japan alliance mechanisms that will expand cooperation on cyber security and defense. Stand up an alliance dialogue on military personnel issues.
