Nuclear Issues

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

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.

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.

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.

A comparative analysis of the United States’ and the Soviet Union’s previously underexplored radiological weapons programs identifies the drivers behind their rise and demise. The findings of this analysis illuminate the factors likely to affect the pursuit of radiological weapons by other states in the future.

Joseph Nye writes that In the cyber realm, the same program can be used for legitimate or malicious purposes, depending on the user’s intent. But if that makes traditional arms-control treaties impossible to verify, it may still be possible to set limits on certain types of civilian targets and negotiate rough rules of the road that limit conflict.

In the past 10 years, oil exports have averaged about $67 billion in Iran. Last year, they dropped by two-thirds, and they are expected to drop below $30 billion this year.  There are reasons to believe that, with appropriate policies, the country can live with this level of oil exports, albeit at a reduced standard of living, and even do itself some good in the long run by reducing its dependence on oil.

Iran has been there before. In 2012, when President Obama ratcheted up U.S. sanctions against Iran, oil exports dropped by 27.5 percent, and GDP fell by 6.2 percent. In 2015, sanctions and the collapse of oil prices further reduced oil exports to $32 billion, a decade-long low, and GDP declined by 1.6 percent. If Iran’s leadership is to successfully resist U.S. demands, it must do more than find ways to evade sanctions. A lot depends on its ability to adopt a plan that reduces the economy’s dependence on oil, while distributing the burden of restructuring equitably across social groups.

For the Islamic Republic, resistance to Washington has become a cultural norm, and it considers independence (esteghlal) as the main achievement of the 1979 revolution.  According to Secretary of State Mike Pompeo, Iran would have to meet 12 conditions before the United States will renegotiate the nuclear deal and consider removing its sanctions. These conditions, which are nothing short of surrender on Iran’s part, are either set to force Iran out of the nuclear deal and therefore trigger the return of UN sanctions, or they are a thinly veiled call for regime change.
