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.

Calder Walton says both seek to topple the United States from atop world stage, with China's blend of money, influence, all-hands-on-deck approach posing the greater threat.

Mina Pollmann explains that between China and North Korea, the logic for increased Japan-South Korea cooperation is clear. All that was lacking was political will. 

Belfer Center experts on the U.S.-China relationship and Middle East issues shared thoughts on the significance of the unexpected Iran-Saudi Arabia agreement brokered by China. 

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.

Christopher Ford, John Harvey, Franklin Miller, Keith Payne, and Bradley Roberts respond to Scott Sagan and Allen Weiner’s spring 2021 article, “The Rule of Law and the Role of Strategy in U.S. Nuclear Doctrine.”

No great breakthroughs or dramatic developments were expected at the Biden-Putin summit, and none was achieved. But the message was clear: There is a new sheriff in town. Putin noticed, describing Biden as very different from Trump—experienced, balanced, and professional.

To date, the U.S. government has not declared that it no longer reserves a purported right to target civilians by way of reprisal, in response to an unlawful attack against U.S. or allied civilians. As we have argued elsewhere, and as Adil Haque recently called on the Biden administration to do, it is time for the United States to acknowledge that customary international law today prohibits targeting civilians in reprisal for an adversary’s violations of the law of war.

When properly applied, the key principles of the law of armed conflict have a profound impact on U.S. nuclear doctrine. Specifically, it would be unlawful for the United States to intentionally target civilians, even in reprisal for a strike against U.S. or allied civilians.

Stephan Walt writes that Trump's foreign-policy instincts might be more sound—but he has forfeited the chance to lead.
