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.

While China is building nuclear reactors faster than any other country in the world, major constraints may limit nuclear energy’s ability to grow to the scale of hundreds of gigawatts that would be required for it to play a major part in decarbonizing China’s energy system. This chapter explores the major constraints on, and risks of, large-scale nuclear energy growth in China, and how both new policies and new technologies might address them. It focuses particularly on the two biggest constraints – economics and siting. Substantial government policies to support nuclear power and advanced reactor systems designed to address some of the key constraints are both likely to be needed for nuclear to have a chance of playing a major role in decarbonizing China’s energy system; nuclear energy’s role may be bigger in the second half of this century than in the first half.

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."

In this issue, we highlight five new books by Belfer Center members.

Bill de Blasio warned New Yorkers on Friday that their city might be subject to retaliatory attacks from Iran. “I’m not saying this to be alarmist,” the mayor said as he and his underlings ticked off—in a slightly alarming fashion—a series of defensive measures the city might take after the American air strike that killed the Iranian general Qassem Soleimani. Though the New York Police Department had received no specific, credible threats, de Blasio and other officials warned of more bag checks at the subways and increased police presence throughout the city. The city is no stranger to terrorism and would maintain a better-safe-than-sorry posture. “If you see something, say something,” de Blasio said.
