Nuclear Issues

Russia's war in Ukraine has brought questions of nuclear deterrence back to the fore, reminding world leaders that risk reduction must remain a top item on the global agenda. Because political and technological change will always introduce new issues, the work of maintaining a "just deterrence" is never done.

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.

Whether they regard it as competitive, cooperative, or confrontational, virtually all observers agree that the U.S.-China relationship is consequential. From cyber norms and AI to military tensions in the Taiwan Strait and the global struggle to turn the tide on climate change, how Washington and Beijing manage their shared future will shape the globe for decades to come. Through research and relationship-building, the Center is dedicated to helping the U.S. and China collaborate and compete without conflict.

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.

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.

The Biden administration has emphasized the importance of alliances and core values of democracy in its foreign policy approach. Given this emphasis, public diplomacy—activities intended to understand, inform, and influence foreign audiences—should be considered an essential tool in achieving our long-term policy objectives in North Korea. Public diplomacy has the potential to spur domestic change in North Korea—change that could result in improved human rights conditions, leading to behavioral change in the Kim regime, and eventually denuclearization.

Proponents of “transactional” diplomacy argue that comprehensive deals to transform political relationships are unrealistic, and that zeroing in on the most pressing issue is the only way to make any tangible progress. The “grand bargainers” retort that any deal that isn’t comprehensive will face fatal opposition from important stakeholders.

Both arguments have some merit, but the perceived distinction between them is a false one: Past engagements with Iran and North Korea were premised on the hope that piecemeal transactions could provide a platform for more sweeping diplomacy. And the best nonproliferation progress has been achieved when all sides perceived diplomatic transactions as incremental steps toward broader reconciliation.

William d'Ambruoso explains why high-level engagement, built on a baseline of deterrence, lessens the chances of war and opens the way for future cooperation in North Korean–U.S. relations.

Trump tied American jobs to endless wars in the Middle East. Biden should link them to renewed diplomacy.

The first 100 days are key to understanding where any presidency is going. Now more than a third of the way into that timeframe, how is President Joe Biden doing in the international policy arena? The World’s host Marco Werman speaks with Nicholas Burns, a former US under secretary of state for political affairs and a former ambassador to NATO.
