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.

Mohammad Tabaar analyzes Iran's strategy to weaken Israel and divide the Middle East.

Calder Walton says both seek to topple the United States from atop world stage, with China's blend of money, influence, all-hands-on-deck approach posing the greater threat.

Joseph Nye argues that prudence results from the fear of creating unintended consequences in unpredictable systems and can develop into a norm of nonuse or limited use of certain weapons or a norm of limiting targets. Something like this happened with nuclear weapons when the superpowers came close to the brink of nuclear war in 1962, during the Cuban missile crisis. The Limited Test Ban Treaty followed a year later.

Wedge strategy theory explains how states use strategic arms control to divide adversaries by affecting their trust, threat perceptions, and beliefs about a commitment’s trade-offs. Examining three landmark arms control negotiations shows how the wedge motive was a key component to these negotiations.

No great breakthroughs or dramatic developments were expected at the Biden-Putin summit, and none was achieved. But the message was clear: There is a new sheriff in town. Putin noticed, describing Biden as very different from Trump—experienced, balanced, and professional.

In anticipation of the entry into force of the landmark Treaty on the Prohibition of Nuclear Weapons (TPNW) on Friday, Laura Grego corresponded with Dr. Aditi Verma, a Stanton Nuclear Security Postdoctoral Fellow at the Harvard University Belfer Center’s Project on Managing the Atom and the International Security Program.  Dr. Verma, who holds undergraduate and doctoral degrees in Nuclear Science and Engineering from MIT, is broadly interested in how nuclear technologies can be designed in collaboration with publics such that traditionally excluded perspectives can be brought into these design processes. She’s one of the five authors of the essay, “A call for antiracist action and accountability in the US nuclear community.”

Joseph Nye writes that In the cyber realm, the same program can be used for legitimate or malicious purposes, depending on the user’s intent. But if that makes traditional arms-control treaties impossible to verify, it may still be possible to set limits on certain types of civilian targets and negotiate rough rules of the road that limit conflict.
