International Security & Defense

As the best documented major crisis in history, in substantial part because Kennedy secretly taped the deliberations in which he and his closest advisers were weighing choices they knew could lead to a catastrophic war, the Cuban missile crisis has become the canonical case study in nuclear statecraft. Over the decades since, key lessons from the crisis have been adapted and applied by the successors of Kennedy and Khrushchev to inform fateful choices.

The authors write that norms can change. This process by which a norm dies often occurs in the wake of security shocks. Just as 9/11 motivated the George W. Bush administration to erode the anti-torture norm, a future security shock could prompt the United States to violate its commitments under the Chemical Weapons Convention.

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.

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.
