North Korea is perilously close to developing strategic nuclear weapons capable of hitting the United States and its East Asian allies. Since their first nuclear test in 2006, North Korea has struggled to perfect the required delivery systems. Kim Jong-un’s regime now appears to be close, however. Sung Chull Kim, Michael D. Cohen, and the volume contributors contend that the time to prevent North Korea from achieving this capability is virtually over; scholars and policymakers must turn their attention to how to deter a nuclear North Korea. The United States, South Korea, and Japan must also come to terms with the fact that North Korea will be able to deter them with its nuclear arsenal. How will the erratic Kim Jong-un behave when North Korea develops the capability to hit medium- and long-range targets with nuclear weapons? How will and should the United States, South Korea, Japan, and China respond, and what will this mean for regional stability in the short term and long term? The international group of authors in this volume address these questions and offer a timely analysis of the consequences of an operational North Korean nuclear capability for international security.

Does state acquisition of nuclear weapons lead to stability and peace or instability and crises? This is one of the great debates in international relations scholarship. Michael D. Cohen argues that nuclear weapons acquisition often does dangerously embolden the acquiring state to undertake coercion and aggression, but that this behavior moderates over time as leaders learn the dangers and limitations of nuclear coercion. This book examines the historical cases of the Soviet Union and Pakistan in depth and also looks at mini-cases involving the United States, China, and India. This book broadens our understanding of how leaders and states behave when they acquire nuclear weapons and is important reading for scholars and students of international relations, security studies, and political psychology.
