How the Next Nuclear Arms Race Will Be Different from the Last One

| 2019

All the world's nuclear-armed states (except for North Korea) have begun modernizing and upgrading their arsenals, leading many observers to predict that the world is entering a new nuclear arms race. While that outcome is not yet inevitable, it is likely, and if it happens, the new nuclear arms race will be different and more dangerous than the one we remember. More nuclear-armed countries in total, and three competing great powers rather than two, will make the competition more complex. Meanwhile, new non-nuclear weapon technologies — such as ballistic missile defense, anti-satellite weapons, and precision-strike missile technology — will make nuclear deterrence relationships that were once somewhat stable less so.

South Korea's Nuclear Hedging?

| Spring 2018

"The credibility of the United States' nuclear umbrella has been questioned time and again by its allies in Europe and Asia since the dawn of the nuclear era. Skepticism toward U.S. extended deterrence to the Republic of Korea (ROK) is particularly high amid their strained relationship in light of political leadership changes in Washington and Seoul as well as North Korea's rapidly advancing nuclear capabilities. A growing sense of abandonment among South Koreans raises the concern that Seoul may go nuclear. However, pursuing nuclear weapons is not likely given the enormous security and economic costs."

The New Era of Counterforce: Technological Change and the Future of Nuclear Deterrence

| Spring 2017

For decades, nuclear deterrence has depended on the impossibility of a first strike destroying a country’s nuclear arsenal. Technological advances, however, are undermining states’ abilities to hide and protect their nuclear arsenals. These developments help explain why nuclear-armed states have continued to engage in security competition: nuclear deterrence is neither automatic nor permanent. Thus, the United States should enhance its counterforce capabilities and avoid reducing its nuclear arsenal.

Would China escalate to nuclear use in a conventional war with the United States? If China believed that U.S. conventional attacks on missiles, submarines, air defenses, and command and control systems threatened the survivability of its nuclear forces or that the United States was preparing a counterforce attack, it might engage in limited nuclear escalation to gain military advantage or coerce the United States. The United States will face difficult trade-offs in deciding how best to manage the risk of nuclear escalation.

Was Ukraine's Nuclear Disarmament a Blunder?

| September 2016

"Ukraine's denuclearization had been a controversial issue even as it was negotiated, leaving bitter traces in the country's political and public discourse. As a student of political science in Kyiv in the mid-1990s, I remember being outraged by the sense of injustice: how could the states that rely on their own nuclear deterrents demand the nuclear disarmament of others? More so that one of these states, Russia, has never fully come to terms with Ukraine's independence. Since then, I came to research a doctoral dissertation on the denuclearization of post-Soviet successor states and, in the process, learned a great deal about Ukraine's nuclear disarmament that dispelled many of my preconceptions."
