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.

Why do we think Vladimir Putin will not use “the bomb” when there is so much evidence that he will?

Recent quantitative scholarship uses warhead counts to examine whether nuclear superiority offers political or military benefits beyond having a secure second-strike capability. These analyses overlook other elements of a state’s nuclear capability such as state perceptions and beliefs.

Wedge strategy theory explains how states use strategic arms control to divide adversaries by affecting their trust, threat perceptions, and beliefs about a commitment’s trade-offs. Examining three landmark arms control negotiations shows how the wedge motive was a key component to these negotiations.

South Korea's conventional counterforce and countervalue strategy is meant to hold North Korea’s nuclear weapons infrastructure, as well as its leadership, at risk independently from the United States. This strategy is often overlooked by policymakers and analysts, who are more focused on discussing Kim Jong Un’s pledges to develop new missile and nuclear capabilities and how the new administration of President Joe Biden should approach the nuclear issue. However, as we highlight in a new article in International Security, South Korea’s strategy increasingly has a determining impact on strategic stability on the Korean Peninsula and on prospects for denuclearization.

South Korea’s conventional counterforce and countervalue strategy is a manifestation of its uncertainties over the reliability of the U.S. alliance. This strategy has significant implications for strategic stability and the potential for denuclearization on the Korean Peninsula.    

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.
