Russia's 2022 invasion of Ukraine illuminated the long profound shadow of nuclear weapons over international security. Russia's nuclear threats have rightfully garnered significant attention because of the unfathomable lethality of nuclear weapons. However, the use of such weapons in Ukraine is only one way—albeit the gravest— that Russia could challenge the global nuclear order. Russia's influence extends deep into the very fabric of this order—a system to which it is inextricably bound by Moscow's position in cornerstone institutions such as the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA). From withdrawing from key treaties to stymieing resolutions critical of misconduct, Moscow has demonstrated its ability to challenge the legitimacy, relevance, and interpretations of numerous standards and principles espoused by the West.

In this American Academy of Arts and Sciences study, Rebecca Davis Gibbons, Stephen Herzog, Wilfred Wan, and Doreen Horschig unpack the challenges to the global nuclear order posed by the Russian war against Ukraine. On February 24, 2022, Russia invaded nonnuclear-armed Ukraine and leveraged threats with its nuclear arsenal as a “shield” to deter third-party intervention. The well-publicized horrors on the ground in Ukraine are, unfortunately, not the only consequences of Russia’s full-scale invasion of its neighbor. The war is having unmistakable effects on how governments, scholars, and the public think about nuclear arms. Not only has Moscow reintroduced the world to the often-unsavory realities of nuclear deterrence, but its suspension of the New Strategic Arms Reduction Treaty (START) and deratification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) have been setbacks for arms control and disarmament. Meanwhile, vulnerable states around the globe may be further incentivized to develop nuclear weapons or seek protection from nuclear-armed patrons to avoid being invaded like Ukraine. Given these changing geopolitical circumstances, how might the Russian war on Ukraine affect the global nuclear order? The authors in this publication conclude that the United States and the broader international community must now more seriously engage with alternatives to traditional arms control, nonproliferation, and disarmament endeavors. Specifically, the authors discuss the increasing prominence of approaches such as the Treaty on the Prohibition of Nuclear Weapons (TPNW)—popularly known as the Nuclear Ban—and risk reduction measures. They assess whether these initiatives can have an impact in reducing nuclear dangers. Additionally, they examine temptations for states to pursue more forceful counterproliferation measures and describe the risks of doing so.

2023 marked eighty years since the wartime adoption of the BRUSA Agreement between Great Britain and the United States. This 1943 document codified the growing relationship between U.S. and U.K. signals intelligence organizations and included policies governing the exchange of personnel and joint regulations for handling sensitive material. Security directives and protocols aligned operational processes between the democratic governments, setting new cooperative standards for nation-states battling authoritarian regimes.

The world has grown more dangerous but also less open to arms control measures that could limit some of the dangers. What can be done? Steven E. Miller offers a tour de force overview of both dismal and hopeful trends within arms control over the past decades, in this first paper of a new HCSS series on Arms Control.

In the World Nuclear Industry Status Report 2021, Mariana Budjeryn writes about the Chernobyl disaster 35 years later, while Ali Ahmad writes about nuclear power and climate change resilience.

The first half century of the nuclear age witnessed the gradual construction of a global nuclear order designed to mitigate nuclear dangers, inhibit arms racing, and prevent the spread of nuclear weapons to additional states. Spurred by the experiences, the dangers, the crises, the near misses, and the frightening risks on display in the early years of the Cold War, sustained efforts were made, in McGeorge Bundy’s vivid phrase, “to cap the volcano.” The time had arrived, Bundy wrote in 1969, for the two great nuclear superpowers “to limit their extravagant contest in strategic weapons,” a contest that had “led the two greatest powers of our generation into an arms race totally unprecedented in size and danger.” In the subsequent twenty-five years after Bundy’s appeal, an increasingly elaborate and institutionalized arms control process produced, with many ups and downs, a detailed web of constraints on the nuclear behavior of the superpowers. The articulated goal was to stabilize the superpower nuclear balance by reinforcing mutual deterrence. The vast nuclear arsenals of the superpowers, however, were not the only source of nuclear danger. In a world in which the number of states armed with nuclear weapons was slowly growing and many additional states had interest in acquiring such weapons or the technology to produce them, there was reason, as Albert Wohlstetter warned in 1961, to be “concerned with the enormous instabilities and dangers of a world with many nuclear powers.” Such a world—“life in a nuclear armed crowd”—Wohlstetter wrote in a later famous study, was widely believed to be “vastly more dangerous than today’s world.” The desire to prevent this unattractive world led to the negotiation of the Nuclear Nonproliferation Treaty (NPT), which entered into force in 1970, and to the subsequent development of an associated regime intended to create legal and technical barriers to the spread of nuclear weapons. Thus, in reaction to the major perceived dangers of the nuclear age, there emerged what Lawrence Freedman calls the “twin pillars” of the global nuclear order: mutual stability in the major nuclear rivalry and nonproliferation to inhibit or prevent the spread of nuclear weapons to additional states.

This essay makes three arguments. First, the US government will need to establish a coronavirus commission, similar to the 9/11 commission, to determine why, since April 2020, the United States has suffered more coronavirus fatalities than any other country in the world. Second, the COVID-19 pandemic represents a watershed for what will be a major national security theme this century: biological threats, both from naturally occurring pathogens and from synthesized biology. Third, intelligence about globalized challenges, such as pandemics, needs to be dramatically reconceptualized, stripping away outmoded levels of secrecy.

Despite the far-reaching effects of the current pandemic,  the essential nature of world politics will not be transformed. The territorial state will remain the basic building-block of international affairs, nationalism will remain a powerful political force, and the major powers will continue to compete for influence in myriad ways. Global institutions, transnational networks, and assorted non-state actors will still play important roles, of course, but the present crisis will not produce a dramatic and enduring increase in global governance or significantly higher levels of international cooperation. In short, the post-COVID-19 world will be less open, less free, less prosperous, and more competitive than the world many people expected to emerge only a few years ago.

This policy brief emphasizes that the European Green Deal's effectiveness in a post Covid-19 world will require the involvement of strategic partners, especially the US. In the context of a potential US withdrawal from the Paris Agreement and the consequential vacuum, it will be even more important to engage the US in implementing the GD. In light of divergence between the US and the EU during past climate negotiations (e.g. Kyoto, Copenhagen, and Paris), we suggest a gradual approach to US engagement with GD initiatives and objectives.

Fueled by aggressive rhetoric from both capitals, Indian and Chinese ground forces engaged in a standoff between June and August 2017. The Doklam crisis, as it became known, stimulated introspection among officials and experts in both states about the future of their relationship. Politically, both strategic communities largely concluded that the peaceful resolution of border disputes is now less likely, forecasting more rivalry than cooperation. Militarily, Indian discussions on the strength of its military position against China in their disputed ground frontier areas have converged on the view that China holds the conventional and nuclear edge over India in this domain.

Based on our analysis of data on the location and capabilities of Indian and Chinese strategic forces and related military units, we conclude that this assessment of the balance of forces may be mistaken and a poor guide for Indian security and procurement policies. We recommend that instead of investing in new nuclear weapons platforms that our analysis suggests are not likely to be required to deter China, New Delhi should improve the survivability of its existing forces and fill the gap in global arms control leadership with an initiative on restraint and transparency.
