Are NATO’s mutual security commitments strong enough today to deter all adversaries? Is the nuclear umbrella as credible as it was during the Cold War? Backed by the full range of US and allied military capabilities, NATO’s mutual defense treaty has been enormously successful, but today’s commitments are strained by military budget cuts and antinuclear sentiment. The United States has also shifted its focus away from European security during the wars in Afghanistan and Iraq and more recently with the Asia rebalance. Will a resurgent Russia change this? The Future of Extended Deterrence brings together experts and scholars from the policy and academic worlds to provide a theoretically rich and detailed analysis of post–Cold War nuclear weapons policy, nuclear deterrence, alliance commitments, nonproliferation, and missile defense in NATO but with implications far beyond. The contributors analyze not only American policy and ideas but also the ways NATO members interpret their own continued political and strategic role in the alliance. In-depth and multifaceted, The Future of Extended Deterrence is an essential resource for policy practitioners and scholars of nuclear deterrence, arms control, missile defense, and the NATO alliance.

This report examines the past, present, and future of US extended deterrence in Asia and outlines how the United States, along with its allies and partners in the region, can counter China's growing military and economic power. The report covers a number of future concerns for the US-South Korea alliance, the US-Japan alliance, and new threats to deterrence in the cyber and space domains. US extended deterrence in East Asia, an essential ingredient to sustain regional peace and prosperity, is increasingly under strain. Revitalizing the strength of US security commitments is therefore a first-order task in Washington's Asia policy.

Examining the future of nuclear deterrence in the 1990s and beyond, this book outlines aspects of the evolving strategic environment. It also projects the likely future of deterrence strategies and strategic force postures. Other topics, such as the Soviet nuclear doctrine are also covered.

“This is a brilliant and hardheaded book. It will frighten those who prefer not to dwell on the unthinkable and infuriate those who have taken refuge in stereotypes and moral attitudinizing.”—Gordon A. Craig, New York Times Book Review Originally published more than fifty years ago, this landmark book explores the ways in which military capabilities—real or imagined—are used, skillfully or clumsily, as bargaining power. Anne-Marie Slaughter’s new introduction to the work shows how Schelling’s framework—conceived of in a time of superpowers and mutually assured destruction—still applies to our multipolar world, where wars are fought as much online as on the ground.

This open access volume surveys the state of the field to examine whether a fifth wave of deterrence theory is emerging. Bringing together insights from world-leading experts from three continents, the volume identifies the most pressing strategic challenges, frames theoretical concepts, and describes new strategies. The use and utility of deterrence in today’s strategic environment is a topic of paramount concern to scholars, strategists and policymakers. Ours is a period of considerable strategic turbulence, which in recent years has featured a renewed emphasis on nuclear weapons used in defence postures across different theatres; a dramatic growth in the scale of military cyber capabilities and the frequency with which these are used; and rapid technological progress including the proliferation of long-range strike and unmanned systems. These military-strategic developments occur in a polarized international system, where cooperation between leading powers on arms control regimes is breaking down, states widely make use of hybrid conflict strategies, and the number of internationalized intrastate proxy conflicts has quintupled over the past two decades. Contemporary conflict actors exploit a wider gamut of coercive instruments, which they apply across a wider range of domains. The prevalence of multi-domain coercion across but also beyond traditional dimensions of armed conflict raises an important question: what does effective deterrence look like in the 21st century? Answering that question requires a re-appraisal of key theoretical concepts and dominant strategies of Western and non-Western actors in order to assess how they hold up in today’s world.

In an era of great power competition, the role of alliances in managing escalation of conflict has acquired renewed importance. Nuclear weapons remain the ultimate means for deterrence and controlling escalation, and are central to US alliances in Europe and the Indo-Pacific. However, allies themselves need to better prepare for managing escalation in an increasingly challenging geostrategic and technological environment for the US and its allies. While the challenge of great power competition is acute at both ends of Eurasia, adversary threats, geography and the institutional context of US alliances differ. This book brings together leading experts from Europe, Northeast Asia, the United States and Australia to focus on these challenges, identify commonalities and differences across regions, and pinpoint ways to collectively manage nuclear deterrence and potential escalation pathways in America’s 21st century alliances. ‘Nuclear weapons play an important role in deterrence and preventing military conflict between great powers, while also posing an existential threat to humanity. It is vital that we have a nuanced understanding of this important challenge, so that such weapons are never used. This book offers many important perspectives and makes a significant contribution to the overall debate about these powerful weapons.’ — The Hon Julie Bishop, Chancellor, The Australian National University, Former Foreign Minister of Australia ‘This timely book identifies a wide range of challenges US alliances both in the Indo-Pacific and Euro-Atlantic face as they seek to ensure the value of US extended deterrence, particular the US nuclear umbrella, against China and Russia. This unique collection of chapters written by experts in US allies in both regions presents widely varying security perceptions and priorities. To understand such differences is the key to globally strengthen the US alliance systems, which are a significant advantage Washington enjoys over the two competitors.’ — Yukio Satoh, former President of The Japan Institute of International Affairs (JIIA) ‘This is a timely and thoughtful collection of essays that should serve to jumpstart public discussion and debate—the absence of which is widely noted and much bemoaned. Each contributor examines an aspect of the complicated, multifaceted nuclear debate by discussing the range of dilemmas from deterrence to disarmament. The various views set out here are more relevant than ever as Russia, China and the United States flex their nuclear muscles in new and sometimes dangerous ways. This book should be read by anyone interested in the preventing the use of nuclear weapons and understanding complexities of alliances in an increasingly dangerous world.’ — Madelyn Creedon, former Principal Deputy Administrator of the US National Nuclear Security Administration and Assistant Secretary of Defense for Global Strategic Affairs
