Nuclear Issues

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.

As Pakistan celebrated the 25th anniversary of its first nuclear tests last month, it also appeared to share more details than usual about its current nuclear posture. Speaking at a seminar hosted by the Institute of Strategic Studies Islamabad on May 24, retired Lt. Gen. Khalid Kidwai provided new details of Pakistan’s otherwise ambiguous nuclear doctrine. What Kidwai says matters because he is currently an advisor to the country’s National Command Authority (NCA), which controls research and development and all other policy matters concerning nuclear weapons. He’s also the former director-general of the Strategic Plans Division (SPD), which is responsible for formulating nuclear policy and strategy as well as the security of nuclear assets.

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.

Stephen Walt asks whether the United States is a good model for other liberal states and whether its policy judgments are ones that others should trust and follow, especially with respect to foreign policy.  He argues that—on balance—the answer to both questions is "no."

A comparative analysis of the United States’ and the Soviet Union’s previously underexplored radiological weapons programs identifies the drivers behind their rise and demise. The findings of this analysis illuminate the factors likely to affect the pursuit of radiological weapons by other states in the future.
