Nuclear Issues

Joseph Nye considers lessons from his own work on preventing the spread of nuclear technology in the 1970s.

Should a nuclear war “never be unleashed?” Can nuclear weapons be used to “ensure the safety of the Russian people?” Both, according to President Vladimir Putin, who has become fond of alternating assertive and conciliatory tones in his messaging on the conditions for the use of nuclear arms. Such discourse comes as he tries to coerce Ukraine into accepting his land grabs and prevent the West from escalating assistance to Kyiv, all while keeping China content.

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.

Polls in the United States and nine allied countries in Europe and Asia show that public support for a nuclear test is very low. If the Trump administration conducts a test, then it shouldn't expect backing from Americans or its closest U.S. partners.

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.

"This week, with little fanfare, one of the world’s key restraints on the spread of nuclear weapons came under scrutiny, as a month-long review of the Non-Proliferation Treaty (NPT) concluded at the United Nations," writes Graham Allison. "Negotiated over the 1960s, the NPT was signed in 1968 and became international law in 1970. As specified by the treaty, members hold a conference every five years to assess the agreement. The exercise offers insight into our nuclear age, and perspective ahead of the coming debate over a treaty to constrain Iran’s nuclear ambitions."
