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.

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.

The Bulletin of Atomic Scientists has published a document from the Pugwash Conference on Science and World Affairs concerning nuclear problems and tensions in the time of COVID-19. The document has been co-signed by a large number of Pugwash colleagues and personalities.

Damir Kovačević, Afrimadona, and Martin Claar's (KAC) statistical adjudication between the potential role of norms versus strategic deterrence in preventing interstate chemical-weapons use is a welcome contribution (Vol. 26, Nos. 3–4, pp. 251–66). The authors conclude that a powerful non-use norm is the most convincing explanation for downtrending chemical warfare. However, closer examination by  David M. Allison and Stephen Herzog in this response to the original article reveals several analytical issues, including inaccurate presentation of data and alternative explanations, that may undermine their results.

The arguments in favor of the United States' declaring that the only purpose of its nuclear weapons is to deter others who possess them from using theirs — in other words, that in no circumstances will this country use nuclear weapons first — are far stronger than the arguments against this stance. It must be hoped that the next US administration will take this no-first-use step promptly.

The International Security Program (ISP) is still accepting applications for 2020–2021.  ISP is a multidisciplinary research group that develops and trains new talent in security studies by hosting pre- and postdoctoral research fellows.
