Nuclear Issues

Russia's 2022 invasion of Ukraine illuminated the long profound shadow of nuclear weapons over international security. Russia's nuclear threats have rightfully garnered significant attention because of the unfathomable lethality of nuclear weapons. However, the use of such weapons in Ukraine is only one way—albeit the gravest— that Russia could challenge the global nuclear order. Russia's influence extends deep into the very fabric of this order—a system to which it is inextricably bound by Moscow's position in cornerstone institutions such as the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA). From withdrawing from key treaties to stymieing resolutions critical of misconduct, Moscow has demonstrated its ability to challenge the legitimacy, relevance, and interpretations of numerous standards and principles espoused by the West.

Kari A. Bingen and Heather W. Williams write that if Russia plans to deploy nuclear weapons in space to target satellites, the threat is definitely serious—and the U.S. should act fast.

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.

On August 6, 1945, the United States dropped an atomic bomb on Hiroshima, Japan, launching the nuclear age. On the 75th anniversary of that somber event, Belfer Center experts reflect on the event and its aftermath. 

Rebecca Davis Gibbons and Stephen Herzog provide an update on current efforts to eliminate nuclear weapons. 

The Bulletin of Atomic Scientists has published a document from the Pugwash Conference on Science and World Affairs concerning nuclear problems and tensions in the time of COVID-19. The document has been co-signed by a large number of Pugwash colleagues and personalities.

A nuclear explosion detonated anywhere by a terrorist group would be a global humanitarian, economic, and political catastrophe. The current COVID-19 pandemic reminds us not to ignore prevention of and preparation for low-probability, high-consequence disasters. For nuclear terrorism, while preparation is important, prevention must be the top priority. The most effective strategy for keeping nuclear weapons out of the hands of terrorists is to ensure that nuclear materials and facilities around the world have strong and sustainable security. Every president for more than two decades has made strengthening nuclear security around the globe a priority. This includes the Trump administration, whose 2018 Nuclear Posture Review states: “[n]uclear terrorism remains among the most significant threats to the security of the United States, allies, and partners.”

It seems unlikely that Russia will again possess the resources to balance U.S. power in the same way that the Soviet Union did during the four decades after World War II. But declining powers merit as much diplomatic attention as rising ones do. Joseph S. Nye worries that the United States lacks a strategy to prevent Russia from becoming an international spoiler.

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.
