Nuclear Issues

Europe after the Russo-Ukrainian War must develop a new security structure to defend against any Russian aggression. The safest option is a non-offensive, confidence-building defense. This option includes proposals such as the “spider in the web” strategy and the “porcupine” strategy to provide for European security in a region threatened by Russian expansion—without relying on the threat of nuclear war. 

The costly Ground-based Midcourse Defense system remains unproven and unreliable in deterring North Korea’s threat to use intercontinental ballistic missiles. An airborne boost-phase intercept system may offer an alternative defense against North Korea without threatening Russian or Chinese deterrents.

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.

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

Why would a state that lacks nuclear weapons choose to fight a state that has them? In this roundtable, four scholars evaluate Paul Avey's explanation for this phenomenon.

The 2018 National Defense Strategy (NDS) is predicated on a single organizing principle: America’s military pre-eminence is rapidly eroding. This is not a new concept. For years, experts have warned that the economic and technological advancements of U.S. adversaries, coupled with the 2008 financial crisis and America’s focus on peripheral conflicts, have caused a decline in America’s military dominance. 

In this context, the advances of near-peer competitors such as China and Russia have created plausible “theories of victory” in potential conflicts across Eastern Europe and East Asia. Competitors’ unaddressed improvements in strategic innovation, economic investment, and dual-use technology increases the risk of conflict and strains the U.S. alliance system. It is urgent that the United States reestablish and maintain credible deterrents against these near-peer competitors. After decades of focusing on post-Cold War ‘shaping’ operations, the American military needs to reinvigorate for full spectrum great power competition.

This report is intended as a blueprint on how to begin that process from graduate students at the Belfer Center for Science and International Affairs at Harvard University. Contained inside are 12 memorandums. Each provides a high-level overview and specific recommendations on a key issue of American defense policy. 

China and the United States hold opposing beliefs about whether nuclear war can be avoided in a potential crisis or armed conflict. Taken together, these opposing beliefs increase the risk of nuclear escalation and can lead to greater crisis instability.

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.
