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.

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.

The costly Ground-based Midcourse Defense system remains unproven and unreliable in deterring North Korea’s threat to use intercontinental ballistic missiles. An airborne boost-phase intercept system may offer an alternative defense against North Korea without threatening Russian or Chinese deterrents.

Graham Allison makes the case that nuclear terrorism is inevitable—if we continue on our present course—and he sets out an ambitious but achievable plan for preventing a catastrophic attack before it’s too late.
