This book chronicles the political-military development of the Korean Peninsula since 1945, with particular attention to North Koreas pursuit of nuclear technology and nuclear weapons, and how it has shaped Northeast Asian security and non-proliferation policy and influenced the strategic choices of the United States and all regional powers. I focus on North Koreas leaders, institutions, political history, and the systems longer-term prospects. How has an isolated, highly idiosyncratic, small state repeatedly stymied or circumvented the policy preferences of much more powerful states, culminating with its withdrawal from the Non Proliferation Treaty (the only state ever to do so) and the testing of nuclear weapons in open defiance of adversaries and allies alike? What does this portend for the regions future? Unlike most of the literature that focuses on US non proliferation policy, this is a book about decision making in North Korea and the states survival in the face of daunting odds. It draws on extensive interviews with individuals in China, South Korea, Japan, Russia, and the EU who have had ample experience in and with North Korea, additional interviews with former US policy makers, and the results from two visits to the North. The author makes extensive use of archival materials from the Cold War International History Project, enabling a far fuller rendering of North Korean history than appears in most of the literature on the North Korean nuclear weapons issue.

How can the United States and South Korea best co-operate to address new security challenges? Can the US-ROK alliance serve to advance South Korea's interests and at the same time help the US to more effectively pursue its own global and regional security objectives? In the context of these questions, the authors explore the possibilities for enhanced co-operation in both traditional and non-traditional spheres.

For close to sixty years, the United States has maintained alliances with Japan and South Korea that have included a nuclear umbrella, guaranteeing their security as part of a strategy of extended deterrence. Yet questions about the credibility of deterrence commitments have always been an issue, especially when nuclear weapons are concerned. Would the United States truly be willing to use these weapons to defend an ally? In this book, Terence Roehrig provides a detailed and comprehensive look at the nuclear umbrella in northeast Asia in the broader context of deterrence theory and U.S. strategy. He examines the role of the nuclear umbrella in Japanese and South Korean defense planning and security calculations, including the likelihood that either will develop its own nuclear weapons. Roehrig argues that the nuclear umbrella is most important as a political signal demonstrating commitment to the defense of allies and as a tool to prevent further nuclear proliferation in the region. While the role of the nuclear umbrella is often discussed in military terms, this book provides an important glimpse into the political dimensions of the nuclear security guarantee. As the security environment in East Asia changes with the growth of North Korea's capabilities and China's military modernization, as well as Donald Trump's early pronouncements that cast doubt on traditional commitments to allies, the credibility and resolve of U.S. alliances will take on renewed importance for the region and the world.

This book explains the origin and historical development of North Korean nuclear weapon dated from the aftermath of World War II. The story of North Korea's nuclear program began when the United States dropped atomic bombs over Hiroshima and Nagasaki in August 1945 which led to Japan's immediate defeat. Surprised by the speed of Japan's surrender, North Korea's founding leader Kim Il-sung vowed to secure nuclear capability to avoid suffering the fate of its eastern neighbor. Based on the author's extensive experience in the academia, government, and intelligence circles, the book traces how the nuclear program has evolved since and explores wide-ranging issues including the positive function of nuclear weapon in Pyongyang's local politics, the history of negotiations between Washington and Pyongyang, the prospects of denuclearization in the Korean Peninsula, the diplomatic and military options presented to US President Donald Trump in dealing with the nuclear threat, and the future scenarios of the North Korean regime and the possibilities of a reunified Korea.With the nuclear weapon crisis likely to persist in the foreseeable time, is it feasible for South Korea to achieve reunification in the Korean Peninsula? Will the six-party members like the US, China, Russia and Japan agree with reunification without denuclearization? Can the issues of nuclear weapon and unification be settled simultaneously in the future? The book seeks to address these questions and more.
