Nuclear Issues

Assaf Zoran examines the dynamics of Iran's shift from operating in the shadows or behind partners and proxies to directly attacking Israel and Pakistan.

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.

Whenever Washington or Moscow unveils a new weapon, ears in the other capital perk up and analysts try to divine how the new system fits into U.S. or Russian military strategy—not least of all, strategy toward its Cold War-era nemesis. But how often do decisions related to national security arise because of institutional forces only tenuously related to states’ strategic planning? More specifically, how do the countries’ respective defense industries influence policy? The Belfer Center’s Russia Matters project asked two scholars—one American, one Russian—to investigate the latter question. Their articles, published in November, reveal fascinating differences (and similarities) in the way this influence is exercised in countries with vastly different political and economic systems.

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.

The regime built around the 1970 Treaty on the Non-Proliferation of Nuclear Weapons (NPT) has helped curtail the spread of nuclear arms for fifty years. In hindsight, it is remarkable only nine states possess the world’s most powerful weapon. The NPT achieved much success during Cold War bipolarity and U.S. unipolarity in its aftermath. But today, China’s rise and Russia’s resurgence have ushered in a new era of emerging multipolarity. Can the treaty withstand the potential challenges of this dynamic environment? There is a real risk that multipolarity may shake the scaffolding of the nonproliferation regime, presenting a significant test to the NPT’s durability. This article identifies four essential elements of the nonproliferation regime: widespread membership, adaptability, enforcement, and fairness. History suggests bipolarity and unipolarity in the international system largely sustained and promoted these NPT features. When international regimes lack such elements, it sharply curtails their long-term efficacy.
