The Dynamics of an Entangled Security Dilemma: China’s Changing Nuclear Posture

| Spring 2023

Chinese strategists increasingly believe that U.S. nonnuclear strategic capabilities threaten China’s nuclear forces. Although there is limited evidence of a shift in its nuclear strategy, China is changing its strategic posture to ensure its second-strike capability, including by relying on advanced conventional weapons (e.g., counterspace capabilities, cyber weapons, and electronic warfare) that can target U.S. missile defense. The dynamics of a nuclear-conventional entangled security dilemma may weaken arms race stability.

Then What? Assessing the Military Implications of Chinese Control of Taiwan

| Summer 2022

An analysis of Taiwan’s military value concludes that its reunification with China would improve Chinese submarine warfare and ocean surveillance capabilities, tipping the military balance in China’s favor. These findings have important implications for U.S. operational planning, policy, and grand strategy.

Russia’s Remaining Weapons Are Horrific and Confounding

| Mar. 23, 2022

Along with concerns over the possible deployment of tactical nuclear weapons, the Biden administration is now warning that the Russian military may launch a chemical weapons attack in Ukraine. Russia has used chemical weapons during past conflicts, notably in Chechnya and Syria, in violation of international law. Russian officials denied Biden’s accusation during a U.N. Security Council meeting Tuesday.

Assessing China-U.S. Inadvertent Nuclear Escalation

| Winter 2021/22

Could a conventional war between China and the United States escalate to the nuclear level? An assessment of three mechanisms of China-U.S. inadvertent escalation—use-it-or-lose-it, unauthorized/accidental, and damage limitation—concludes that the risk of China-U.S. inadvertent nuclear escalation is extremely low.

The Two Faces of Opposition to Chemical Weapons: Sincere Versus Insincere Norm-Holders

| 2021

The authors' findings advance a specific debate on the strength of weapons taboos, while their conceptualization of insincere norm-holders and methodological application have broader implications for how scholars might think about and measure norms in international politics.

The End of Cyber-Anarchy?

| January/February 2022

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.

'What About China?' and the Threat to US–Russian Nuclear Arms Control

The administration of President Donald J. Trump has consistently used fear of China to undermine nearly five decades of bipartisan consensus on US–Russian nuclear arms control. The negative consequences of these actions may last far beyond the Trump presidency. If generations of agreement between Democrats and Republicans on bilateral nuclear treaties with Russia erode, it will pose a significant setback to US national security and global stability. Future leaders may ultimately need to consider new approaches to nuclear risk reduction that preserve the benefits of the arms control regime.

China is speeding up its plutonium recycling programs

| July 20, 2020

Since 1983, China has had the objective of developing breeder reactors to run on recycled plutonium. Since 2004, it has been progressing through three stages of its plutonium recycling strategy: from pilot to demonstration to commercial facilities. At the first stage, in 2010, China began testing a pilot civilian reprocessing plant and running a small experimental fast reactor. Although those pilot facilities did not perform well, since 2015 China has moved forward to the second stage, which includes a demonstration reprocessing plant, a mixed-oxide fuel facility, and two demonstration liquid-sodium-cooled fast-neutron reactors. Recent satellite images and other information show construction of those demonstration facilities is actively underway. Meanwhile, the China National Nuclear Corporation is pushing toward the third stage by negotiating with France’s nuclear fuel cycle company Orano (formerly Areva) over the purchase of a large commercial reprocessing plant, and has proposed construction of large commercial fast-neutron reactors by 2028.

Living with Uncertainty: Modeling China's Nuclear Survivability

| Spring 2020

A simplified nuclear exchange model demonstrates that China’s ability to launch a successful nuclear retaliatory strike in response to an adversary’s nuclear first strike has been and remains far from assured. This study suggests that China’s criterion for effective nuclear deterrence is very low.

The study of existential risk — the risk of human extinction or the collapse of human civilization — has only recently emerged as an integrated field of research, and yet an overwhelming volume of relevant research has already been published. To provide an evidence base for policy and risk analysis, this research should be systematically reviewed. In a systematic review, one of many time-consuming tasks is to read the titles and abstracts of research publications, to see if they meet the inclusion criteria. The authors show how this task can be shared between multiple people (using crowdsourcing) and partially automated (using machine learning), as methods of handling an overwhelming volume of research.
