Nuclear Issues

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.

This year's G7 summit in Hiroshima sees nuclear disarmament and non-proliferation sitting high on the agenda, amid rising tensions between the nuclear states and an increasingly divided international order.  Six contributors offer their analyses, including the Belfer Center's Mayumi Fukushima.

There seems to exist a general consensus on how to conceptualize cooperation in the field of international relations (IR). The authors argue that this impression is deceptive. In practice, scholars working on the causes of international cooperation have come to implicitly employ various understandings of what cooperation is. Yet, an explicit debate about the discipline's conceptual foundations never materialized, and whatever discussion occurred did so only latently and without much dialog across theoretical traditions. In this article, the authors develop an updated conceptual framework by exploring the nature of these differing understandings and situating them within broader theoretical conversations about the role of cooperation in IR.

Stephen Walt explains why Putin understood that Ukraine's fate was more important to Russia than it was to the West.

To begin to appreciate what President Biden, Chairman of the Joint Chiefs of Staff Mark Milley, CIA Director Bill Burns, and National Security Advisor Jake Sullivan understand that most of the press and talking heads who have been discounting nuclear risks posed by the war in Ukraine don’t, it is useful to consider answers to seven questions.

Stephen Walt offers a tentative and far-from-comprehensive survey of what scholars have to say about the war in Ukraine.

Abolghasem Bayyenat argues that rather than insisting that the JCPOA be restored strictly in its original form and implemented per its letter, the parties should seek to redress the agreement's imbalance in regard to its enforcement mechanisms and delivery of its economic benefits.

The probability of terrorists getting and using a nuclear bomb appears to be low—but the consequences if they did would be so devastating that it is worth beefing up efforts to make sure terrorists never get their hands on a nuclear bomb’s essential ingredients. To see the possibilities, we need to look at motive, capability, and opportunity.

On Sept. 13, 2021, Prof. Matthew Bunn presented his work on the evolving global threat to nuclear and radiological transports to the Transport Security Unified Stakeholders Group.
