Abstract:
The term “nuclear tripolarity” describes a world in which China has joined the United States and Russia as a leading nuclear power. As China modernizes its existing nuclear forces and deploys new weapons, it is on track to roughly double its deployed nuclear arsenal in the next few years—from approximately 350 to 700 deliverable warheads. The US Department of Defense projects that China will go further, expanding its arsenal to at least 1,500 warheads by 2035.1 At those force levels, China’s arsenal would be comparable to US and Russian deployed nuclear forces, currently capped at 1,550 by the New START Treaty.2 What are the consequences of emerging tripolarity for US nuclear strategy and force posture? If the United States retains its current approach to nuclear force planning, the growth of China’s arsenal (and the ongoing modernization of Russia’s nuclear weapons) will likely compel the United States to significantly increase its own arsenal. The easiest way to do so would be to upload one to two thousand additional warheads from US reserves onto existing delivery systems when the New START treaty expires in 2026. Unfortunately, a major increase in US forces would likely mark just another step in an intensifying arms competition among the three leading nuclear powers, since China and Russia would then feel pressure to respond.

Abstract:
The United States and Chinese governments, for the foreseeable future, will have the resources to keep each other’s societies vulnerable to nuclear mass destruction. If these governments are not self-destructive, they will want to keep their competition from escalating into armed conflict that could lead to nuclear war. The constructs of strategic stability and mutual vulnerability can help significantly if both governments embrace them and interpret them similarly or even if the leaders of the two countries accurately understand how they differ in their perspectives on them. Unfortunately, to date, on these issues the United States and China are like a quarrelling married couple who tried therapy for one or two appointments, found it dissatisfying, and then alternated in making excuses for not trying again, perhaps with a different therapist or format. Each says they have tried and the other doesn’t listen or understand. Both suspect that the other isn’t saying what they really feel or want; what they really feel is hostility and distrust and what they really want is to get richer and more powerful without being hassled or attacked. It would be easier if they could just go their separate ways, but the property and wealth they depend on will be lost (or at least severely diminished) if they split up or do each other harm. This paper suggests that U.S. and allied interests require persistence in inviting China to dialogue on strategic stability; to demonstrate goodwill, the United States should acknowledge mutual vulnerability as a fact and necessary policy. The need for both moves is reflected in the fact that neither government has defined what it might mean by stability or mutual vulnerability. To help test intentions and prompt harder thinking, the paper plays the role of therapist and offers definitions of both concepts—strategic stability and mutual vulnerability—so that the two sides can critique them more freely and without recrimination. These definitions are broader and deeper than usual, reflecting the growing problem of managing escalation of conventional conflict to nuclear war, the scenario that drives U.S. and Chinese concerns and military posturing. Further, broader definitions are necessary to comprehend the dangers stemming from the entanglement of conventional, cyber, and nuclear weapons and command and control systems. The paper then sketches four benefits of declaring mutual vulnerability, contrary to opponents of the idea, before discussing steps that the United States and China could subsequently take to reflect and build each other’s confidence in such a policy. Finally, if perceived U.S. requirements in the future will be greater than the arsenal needed to deter or defeat Russia or China alone, how will Russia and China be persuaded not to try to build up to balance the additional U.S. force? In other words, if the United States is in two separate but interacting arms races (and deterrence relationships), how could each opponent (China and Russia) be persuaded to negotiate limits on their arsenal lower than the total the United States would insist on possessing to deter two nuclear opponents? Answers to these questions will affect strategic stability and mutual vulnerability of all parties but will take a long time to develop. To begin the process, the paper suggests asking Chinese leaders whether their silence on Putin’s nuclear first-use threats means that China has changed its own policy on nuclear use or that it never took a no-first-use policy seriously in the first place. Is China concerned that the capabilities that the United States and its allies may develop to strengthen defenses against Russia could be used against China too, and if so, might arms control be a wiser approach? Ultimately, the paper suggests that if China and the United States can sustain a process of serious dialogue, they will keep their relationship from worsening even if they cannot formally restrain their competition. And if dialogue leads one to ask the other for deeds to demonstrate goodwill, the paper has suggested some such deeds that could be undertaken with no security hazard and only slight political risk. No one should have the illusion that happiness is in this couple’s future. All this work would be to allow a nonviolent cohabitation that is better than the alternative of destitute divorce or murder-suicide.

3. Multidomain Deterrence and Strategic Stability in China

Working Paper
Institution:
Stockholm International Peace Research Institute
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.

Institution:

Abstract:
North Korea is conducting further missile tests to check new types of weapons and increase the credibility of its nuclear deterrence. The adoption of a new nuclear doctrine that allows pre-emptive nuclear strikes also serves this purpose. North Korea is taking advantage of the period of tension between the U.S., Russia, and China, which prevent the UN Security Council from adopting further sanctions. In this situation, the U.S. and its allies should strengthen defence and deterrence capabilities against North Korea and set achievable goals to reduce the risk of escalation of tensions before possible negotiations.

Abstract:
The North Korean nuclear and ballistic missile crisis is the most serious proliferation crisis the European Union (EU) and its member states currently face on the world stage. Despite the staging of diplomatic meetings, the threat caused by this crisis to European interests, in terms of proliferation, instability and to prosperity, persists. It is now essential that the EU and its member states move from a strategy of critical engagement to implementing a more proactive strategy of credible commitments in four areas: political engagement, non-proliferation, the implementation of restrictive measures and engagement with the North Korean people. Such a renewed strategy should be highly coordinated, build on the many initiatives already being taken and facilitated by the appointment of an EU Special Representative on North Korea.

6. North Korea’s Nuclear Program: The Early Days, 1984–2002

Abstract:
The North Korean nuclear program has been a major intelligence and policy challenge for more than 30 years. Former Secretary of Defense Bill Perry described the problem as “perhaps the most unsuccessful exercise of diplomacy in our country’s history.”1 Donald Gregg, who was CIA station chief in Seoul as well as US ambassador to South Korea, called North Korea the “longest running intelligence failure in the history of American espionage.”2 To be fair, Gregg was referring specifically to a lack of success in recruiting human sources—not necessarily errors in specific or overall assessments. Nonetheless, his comment underscores the difficulty of figuring out what North Korea is up to. In 2005, the Commission on the Intelligence Capabilities of the United States Regarding Weapons of Mass Destruction (WMD), which was convened to investigate the failed 2002 national intelligence estimate on Iraqi WMD capabilities, indicated that we know “disturbingly little about the weapons programs and even less about the intentions of many of our most dangerous adversaries,”3 presumably including North Korea. Today we know a lot more about North Korea’s nuclear program— but mostly it is what they want us to know. Pyongyang has conducted six nuclear tests. We know that North Korea has nuclear weapons, a significant fissile material production capacity, and an ambitious nuclear and missile development effort. These programs are completely unconstrained. The United States has tried many approaches to deal with the problem over the years, and intelligence has played a key role in support. Are there lessons to be learned from this experience? Obviously, it’s a very big question and I will sketch out just a few thoughts, mostly from an intelligence perspective: What we knew and when and how we thought about the problem. North Korea was one of many issues I worked on as an analyst and manager in CIA until my retirement in 2006. The views that follow are my own, of course, and the specific information is drawn from the extensive public literature on the issue, as well as declassified intelligence documents.

7. US Nonproliferation Cooperation with Russia and China

Institution:

Abstract:
The United States has at times worked cooperatively with Russia and China to promote shared nonproliferation objectives. But with no end in sight to the current precipitous decline in Washington’s bilateral relations with Moscow and Beijing, constructive engagement on today’s nonproliferation challenges has become increasingly problematic. Unless the United States and its two great power competitors can find a way to carve out areas of cooperation in otherwise highly adversarial relationships, the remarkably positive record of international efforts to prevent additional countries from acquiring weapons will be difficult to sustain. From sometimes partners to frequent foes, this Occasional Paper examines the history of US cooperation with Russia and China on key issues including Iran, North Korea, Syria, international nonproliferation mechanisms, and nuclear security. It also outlines the obstacles to future nonproliferation cooperation, as well as the growing proliferation threats that require such cooperation. Most importantly, it identifies several possible areas where the United States can hope to find common ground with both countries. With relationships with Russia and China reaching new lows and unlikely to improve for the foreseeable future, finding a way to for the United States to work cooperatively with both countries will not be easy. Bridges to constructive engagement have been burned and will be difficult to rebuild. However, the author points out that constituencies for cooperation remain in all three countries, including in government bureaucracies. “As hard as it may be to find common ground in otherwise highly adversarial relationships, it is imperative that the US administration in office after January 2021 make every effort to do so. Cooperation with America’s two great power rivals will not always guarantee success, but the absence of such cooperation will surely increase the risk of failure.”

8. Increasing Nuclear Threats through Strategic Missile Defense

Abstract:
Growing concerns about third-country nuclear threats led the United States to withdraw from the ABM Treaty’s constraints on the size and scope of ballistic missile defense arsenals in 2002. Inaccurate and alarmist projections of “rogue state” ICBM threats were critical in winning support for the decision to withdraw from the treaty and to sustain the multi-billion dollar annual price tag for developing, deploying, and expanding strategic missile defenses. But 18 years after Washington abandoned the treaty, North Korea is the only rogue state that could pose a near-term nuclear threat against the American homeland—and U.S. missile defense interceptors and radars have not even delivered high confidence of being able to protect against this threat. Meanwhile, the absence of limits on U.S. strategic missile defenses and prudent, worst-case concerns in Moscow and Beijing about their future expansion are fueling resistance to additional nuclear arms reductions and stability measures. The end result is that the exponential threats posed by Russia and China are getting worse and the chances of a disastrous nuclear arms race are increasing. This analysis argues that the nuclear threat confronting the United States is multilateral, three-dimensional, and interrelated. Unless the United States acknowledges the role of missile defenses in this complicated reality, it will not be able to realize the full benefits that arms control offers.

9. At a Crossroads? China-India Nuclear Relations After the Border Clash

Institution:
Carnegie Endowment for International Peace
Abstract:
While both countries may think the situation is under control, dismissive attitudes and misperceptions could end up fueling a dangerous competition. On June 15, 2020, a lethal military conflict over disputed territory in the Himalayas shook the edifice of China-India relations. The clash in the Galwan Valley along their shared border is the gravest military confrontation the two nuclear powers have faced in fifty years. This event and ongoing tensions focus attention on the long-standing but tempered competition between China and India. One of the most interesting puzzles of that relationship is why nuclear weapons, which both possess, have not played a more important role. With the potential for a major reset in China-India ties after the Ladakh crisis, are Beijing and New Delhi finally approaching a long-anticipated crossroads in their nuclear relations? The findings reveal that while Indian security analysts give serious attention to China’s nuclear policy and capabilities, Chinese analysts maintain a dismissive attitude about the relevance of nuclear weapons in China-India relations. The attitude stems from a widely held view that India’s indigenous military technologies are significantly behind China’s and that China will continue widening the gulf between the two countries’ conventional and nuclear capabilities. However, Chinese analysts do not appear to fully appreciate the long-term destabilizing implications of this growing gap. India may feel pressure to build out its nuclear arsenal, and this could further threaten the fragile stability between India and Pakistan. Chinese experts tend to underestimate the role Beijing may have in shaping New Delhi’s threat perception and nuclear strategy.

10. North Korea’s Shift to Diplomacy in 2018: A Result of U.S. Pressure or North Korean Security Calculus?

Abstract:
After conducting a record number of missile and nuclear tests in 2016 and 2017, North Korea dramatically changed its policy approach and embarked on a diplomatic initiative in 2018. It announced a self-imposed halt on missile and nuclear tests and held summit meetings with the United States, China, and South Korea from spring of that year. Why did North Korea shift its policy approach? This paper evaluates four alternative explanations. The first is that the change was driven by North Korea’s security calculus. In other words, North Korea planned to achieve its security goals first before turning to diplomacy and successfully followed through with this plan. The second is that U.S. military threats forced North Korea to change its course. The third is that U.S.-led sanctions caused North Korea to shift its policy by increasing economic pain on the country. The fourth is that diplomatic initiatives by South Korea and others prompted North Korea to change its position. This paper examines the actions and statements of the United States, North Korea, China, South Korea, and Russia leading up to and during this period to assess these four explanations. It concludes that military threats and economic pain did not dissuade North Korea from obtaining what it considered an adequate level of nuclear deterrence against the United States and that North Korea turned to diplomacy only after achieving its security goals. External pressure may have encouraged North Korea to speed up its efforts to develop the capacity to strike the United States with a nuclear-armed missile, the opposite of its intended effect. Diplomatic and economic pressure may have compelled Kim Jong Un to declare that North Korea had achieved its “state nuclear force” before conducting all the nuclear and ballistic missile tests needed to be fully confident that it could hit targets in the continental United States. These findings suggest that if a pressure campaign against North Korea is to achieve its intended impact, the United States has to more carefully consider how pressure would interact with North Korean policy priorities. Pressure should be applied only to pursue specific achievable goals and should be frequently assessed for its impact.

11. China on Arms Control, Nonproliferation, and Strategic Stability

Author:
Nancy Gallagher

Content Type:
Working Paper
Institution:
Center for International and Security Studies at Maryland (CISSM)
Abstract:
China and the United States view each other as potential adversaries with mixed motives and divergent value systems, yet both can benefit from cooperation to reduce the risk of war, avert arms races, and prevent proliferation or terrorist access to weapons of mass destruction. The two countries have more common interests, fewer ideological differences, and greater economic interdependence than the United States and the Soviet Union had during the Cold War. In principle, arms control broadly defined, i.e., cooperation to reduce the likelihood of war, the level of destruction should war occur, the cost of military preparations, and the role of threats and use of force in international relations, could be at least as important in this century as it was in the last. In practice, though, China’s rise as a strategic power has not been matched by a corresponding increase in the kinds of cooperative agreements that helped keep the costs and risks of superpower competition from spiraling out of control. Why not? This paper argues that because China’s strategy rests on different assumptions about security and nuclear deterrence than U.S. strategy does, its ideas about arms control are different, too. China has historically put more value on broad declarations of intent, behavioral rules, and self-control, while the United States has prioritized specific quantitative limits on capabilities, detailed verification and compliance mechanisms, and operational transparency. When progress has occurred, it has not been because China finally matched the United States in some military capability, or because Chinese officials and experts “learned” to think about arms control like their American counterparts do. Rather, it has happened when Chinese leaders believed that the United States and other countries with nuclear weapons were moving toward its ideas about security cooperation--hopes that have repeatedly been disappointed. Understanding Chinese attitudes toward security cooperation has gained added importance under the Trump administration for two reasons. Trump’s national security strategy depicts China and Russia as equally capable antagonists facing the United States in a “new era of great power competition,” so the feasibility and desirability of mutually beneficial cooperation with China have become more urgent questions. The costs and risks of coercive competition will keep growing until both sides accept that they outweigh whatever benefits might accrue from trying to maximize power and freedom of action in a tightly interconnected world.

12. Converting Maximum Pressure to Maximum Leverage: The Role of Sanctions Relief in Negotiations with North Korea

Author:
Daniel Wertz
Publication Date:

Content Type:
Working Paper
Institution:
Korea Economic Institute of America (KEI)
Abstract:
The Trump administration’s maximum pressure campaign has led to the imposition of a nearly comprehensive international sanctions regime targeting North Korea and its nuclear weapons program. With negotiations underway, the question of whether to provide North Korea with partial sanctions relief in exchange for limited concessions on its nuclear program has been a major point of dispute between Washington and Pyongyang. This paper looks at sanctions as a form of coercive bargaining and examines the logic and challenges behind a strategy of incrementally exchanging relief from pressure for compliance with the sanctioner’s demands. It argues that taking an “all-or-nothing” approach to sanctions relief risks missing an opportunity to reduce the threat of North Korea’s nuclear program and squandering hard-won negotiating leverage, and outlines a framework for how a step-by-step approach might proceed.

Abstract:
On 23-24 June 2019 a delegation from Pugwash travelled to Iran to participate in a specially-arranged two-day meeting organized together with the Institute for Political and International Studies (IPIS) in Tehran. The central focus of the discussions was the current status of the Joint Comprehensive Plan of Action (JCPOA), more than one year after the United States withdrew from implementing it, and the ensuing program of ever-tightening sanctions imposed by the US on Iran that has dramatically increased tension in the Middle East. The meeting also put this into context by looking at the regional situation of arms control, as well as Iran’s relations with China, Russia, the EU, and its neighbours including Afghanistan.
