Nuclear Issues

Kari A. Bingen and Heather W. Williams write that if Russia plans to deploy nuclear weapons in space to target satellites, the threat is definitely serious—and the U.S. should act fast.

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.

William d'Ambruoso explains why high-level engagement, built on a baseline of deterrence, lessens the chances of war and opens the way for future cooperation in North Korean–U.S. relations.

Horizontal nuclear proliferation presents what is sometimes referred to as the "Nth country problem," or identifying which state could be next to acquire nuclear weapons. Nuclear fuel cycle technologies can contribute to both nuclear power generation and weapons development. Consequently, observers often view civilian nuclear programs with suspicion even as research on nuclear latency and the technological inputs of proliferation has added nuance to these discussions. To contribute to this debate, the author puts forth a simple theoretical proposition: En route to developing a civilian nuclear infrastructure and mastering the fuel cycle, states pass through a proliferation "danger zone."

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 world will soberly commemorate the 33rd anniversary of the Chernobyl nuclear power plant catastrophic accident on Friday, April 26, 2019.  Some may wonder why bother with a gone-by historical event that happened in a distant land — a country that no longer exists — the former Soviet Union (now Ukraine).  On the contrary, Chernobyl and its legacy, with its specters of lingering human toll, radiation contamination, and the massive new shelter ("New Safe Confinement") installed over the old sarcophagus encasing the reactor, will be with us for a long time.
