Nuclear Issues

This week in Say More, Project Syndicate talks with Joseph S. Nye, Jr., an emeritus professor at Harvard Kennedy School, a former U.S. assistant secretary of defense, and the author, most recently, of A Life in the American Century.

In this Q&A, Joseph S. Nye talks about his advice for the interim and future president of Harvard in the wake of Claudine Gay's resignation, which countries should be highest on our radar to prevent the threat of nuclear war, what role the U.S. should play in the Russia-Ukraine war, the significance of U.S. alliances in the Middle East, and more.

Joseph Nye writes that even at this early stage, there are at least eight lessons— some old, some new— that the world is learning (or relearning) from the war in Ukraine.

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.

In his new book, Do Morals Matter? Presidents and Foreign Policy from FDR to Trump, Joseph S. Nye developed a scorecard to determine how U.S. presidents since 1945 factored questions of ethics and morality into their foreign policy. In an interview, Henry Farrell asked him a few questions to get to the heart of his findings.
