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.

Joseph Nye considers lessons from his own work on preventing the spread of nuclear technology in the 1970s.

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.

Kennedy’s statecraft in the missile crisis provides a rich source of clues that can help illuminate the challenge the United States now faces, and the choices President Joe Biden is making.

As the best documented major crisis in history, in substantial part because Kennedy secretly taped the deliberations in which he and his closest advisers were weighing choices they knew could lead to a catastrophic war, the Cuban missile crisis has become the canonical case study in nuclear statecraft. Over the decades since, key lessons from the crisis have been adapted and applied by the successors of Kennedy and Khrushchev to inform fateful choices.

The political crisis and human tragedy unfolding in Europe as a result of Russia’s invasion of Ukraine will dominate national security debates for the foreseeable future. As the world’s eyes focus on this conflict in the coming days and weeks, the Biden administration will likely also be rolling out key nuclear policy documents. There will be many issues to consider, but one that shouldn’t be missed—the urgency of which has been highlighted by recent developments in Ukraine, and particularly around the Chernobyl site—is the security of nuclear materials.

States frequently acquire proof that other states have violated norms. Yet, existing theories do not fully explain how states wield such proof to coerce wrongdoers. Four case studies of nuclear proliferation probe a novel theory of how states coerce norm violators by concealing, sharing privately, or publicizing proof of guilt.

Wedge strategy theory explains how states use strategic arms control to divide adversaries by affecting their trust, threat perceptions, and beliefs about a commitment’s trade-offs. Examining three landmark arms control negotiations shows how the wedge motive was a key component to these negotiations.

The probability of terrorists getting and using a nuclear bomb appears to be low—but the consequences if they did would be so devastating that it is worth beefing up efforts to make sure terrorists never get their hands on a nuclear bomb’s essential ingredients. To see the possibilities, we need to look at motive, capability, and opportunity.

Today, US-Russian political relations are as poisonous as they have been in decades. Former Secretary of Energy Ernest Moniz and former Senator Sam Nunn have warned that “not since the Cuban Missile Crisis of 1962 has the risk of a US-Russian confrontation involving the use of nuclear weapons been as high as it is today." In Washington, there is more talk of new sanctions than of paths to cooperation. Nevertheless, there are some hints in both capitals that despite the larger political confrontation, both sides would like to find areas of common interest where cooperation might be possible. The next time the US and Russian presidents meet and issue a joint statement, they should include direction for their nuclear experts to begin working together again— on an agenda that includes nuclear energy, nuclear security, nonproliferation, technologies for verifying future arms agreements, and more.
