This book provides some important perspectives on the emerging nuclear order. The contributors discuss most burning questions of the day: What are the challenges to the global nuclear regime? What are the consequences of a nuclear Iran for West Asian peace and stability? Will it give rise to a nuclear quest among the important West Asian states? How would the West respond in such an eventuality? What would be the response of major Asian powers to nuclear Iran? What are the consequences of changes in the East Asian nuclear order for stability and peace in the region and beyond? How would major regional players respond? What are the implications of non-state actors acquiring nuclear weapon technology and capabilities? What did the international community learn from the discovery of the A.Q. Khan network? What are the possibilities for international cooperation against nuclear proliferation?

The world is at an inflection point. Advancing technologies are creating new opportunities and challenges. Great demographic changes are occurring rapidly, with significant consequences. Governance everywhere is in disarray. A new world is emerging. These are some of the key insights to emerge from a series of interdisciplinary roundtables and global expert contributions hosted by the Hoover Institution. In these pages, George P. Shultz and James Timbie examine a range of issues shaping our present and future, region by region. Concrete proposals address migration, reversing the decline of K–12 education, updating the social safety net, maintaining economic productivity, protecting our democratic processes, improving national security, and more. Meeting these transformational challenges will require international cooperation, constructive engagement, and strong governance. The United States is well positioned to ride this wave of change—and lead other nations in doing the same.

This book relates a complex ethical (re)assessment of the continued reliance by some states on nuclear weapons as instruments of state power. This (re)assessment is more urgent considering the relatively recent intensification of great power conflict dynamics and the nuclear-weapon states’ recommitments to modernizing, augmenting, or tailoring their nuclear forces to address vital state and alliance interests. And, especially since the beginning of the administration of U.S. President Donald J. Trump, these recommitments have accelerated the degree to which the political and moral dilemmas of (the threat of) nuclear use define and intensify existential risks for specific states and the international community at large. To execute this (re)assessment, this book details how strategic, political, legal, and moral reasoning are deeply intertwined on the questions of vital state and global values. Its ontological assumptions are taken from a broadly construed IR Constructivist stance, and its epistemological approach applies non-ideal moral principles informed by Kantian thought to selected problems of nuclear-armed security competition as they evolved since President Barack Obama’s 2009 Prague Declaration. This non-ideal moral approach employed is committed to the view that the dual imperatives of humanity’s survival and the common security of states requires an international order which privileges considerations of justice over power-political considerations. This non-ideal moral approach is a necessary element of theorizing a set of practices to effectively address the challenges and dilemmas of reordering international politics in terms of justice.

Deterrence remains a primary doctrine for dealing with the threat of nuclear weapons in the 21st century. The author reviews the history of nuclear deterrence and calls for a renewed intellectual effort to address the relevance of concepts such as first strike, escalation, extended deterrence, and other Cold War-era strategies in today's complex world of additional superpowers, smaller nuclear powers, and nonstate actors.

Nuclear Logics examines why some states seek nuclear weapons while others renounce them. Looking closely at nine cases in East Asia and the Middle East, Etel Solingen finds two distinct regional patterns. In East Asia, the norm since the late 1960s has been to forswear nuclear weapons, and North Korea, which makes no secret of its nuclear ambitions, is the anomaly. In the Middle East the opposite is the case, with Iran, Iraq, Israel, and Libya suspected of pursuing nuclear-weapons capabilities, with Egypt as the anomaly in recent decades. Identifying the domestic conditions underlying these divergent paths, Solingen argues that there are clear differences between states whose leaders advocate integration in the global economy and those that reject it. Among the former are countries like South Korea, Taiwan, and Japan, whose leaders have had stronger incentives to avoid the political, economic, and other costs of acquiring nuclear weapons. The latter, as in most cases in the Middle East, have had stronger incentives to exploit nuclear weapons as tools in nationalist platforms geared to helping their leaders survive in power. Solingen complements her bold argument with other logics explaining nuclear behavior, including security dilemmas, international norms and institutions, and the role of democracy and authoritarianism. Her account charts the most important frontier in understanding nuclear proliferation: grasping the relationship between internal and external political survival. Nuclear Logics is a pioneering book that is certain to provide an invaluable resource for researchers, teachers, and practitioners while reframing the policy debate surrounding nonproliferation.

A leading international security strategist offers a compelling new way to "think about the unthinkable." The cold war ended more than two decades ago, and with its end came a reduction in the threat of nuclear weapons—a luxury that we can no longer indulge. It's not just the threat of Iran getting the bomb or North Korea doing something rash; the whole complexion of global power politics is changing because of the reemergence of nuclear weapons as a vital element of statecraft and power politics. In short, we have entered the second nuclear age. In this provocative and agenda-setting book, Paul Bracken of Yale University argues that we need to pay renewed attention to nuclear weapons and how their presence will transform the way crises develop and escalate. He draws on his years of experience analyzing defense strategy to make the case that the United States needs to start thinking seriously about these issues once again, especially as new countries acquire nuclear capabilities. He walks us through war-game scenarios that are all too realistic, to show how nuclear weapons are changing the calculus of power politics, and he offers an incisive tour of the Middle East, South Asia, and East Asia to underscore how the United States must not allow itself to be unprepared for managing such crises. Frank in its tone and farsighted in its analysis, The Second Nuclear Age is the essential guide to the new rules of international politics.

“An excellent contribution to the debate on the future role of nuclear weapons and nuclear deterrence in American foreign policy.” ―Contemporary Security Policy This book is a counter to the conventional wisdom that the United States can and should do more to reduce both the role of nuclear weapons in its security strategies and the number of weapons in its arsenal. The case against nuclear weapons has been made on many grounds—including historical, political, and moral. But, Brad Roberts argues, it has not so far been informed by the experience of the United States since the Cold War in trying to adapt deterrence to a changed world, and to create the conditions that would allow further significant changes to U.S. nuclear policy and posture. Drawing on the author’s experience in the making and implementation of U.S. policy in the Obama administration, this book examines that real-world experience and finds important lessons for the disarmament enterprise. Central conclusions of the work are that other nuclear-armed states are not prepared to join the United States in making reductions, and that unilateral steps by the United States to disarm further would be harmful to its interests and those of its allies. The book ultimately argues in favor of patience and persistence in the implementation of a balanced approach to nuclear strategy that encompasses political efforts to reduce nuclear dangers along with military efforts to deter them. “Well-researched and carefully argued.” ―Foreign Affairs
