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.

Through the examination of different themes and subjects the book provides an in depth analysis of the concept of deterrence and its utility in dealing effectively with current threats. Although the concept of deterrence precedes the Cold War, in modern times and in its traditional form deterrence is seen as the product of the Cold War, which transformed 'narrow' deterrence approaches into widespread orthodoxy. Increasingly however emerging threats and challenges call into question the traditional concept of deterrence. There are many elements that challenge the concept of deterrence and its effectiveness. For instance it is not just that the concept can be ambiguous and broad, but also there have to be a number of conditions for it to be successfully implemented. This collection contributes to a growing field of research in a relatively under-studied area of interrogating the concept of deterrence itself through a multi-disciplinary approach. Through the use of primary and secondary sources, as well as interviews, this book covers a wide range of disciplinary approaches on deterrence and the contributors cover a broad array of subjects. The research assembled here focuses on deterring extremism, conflict resolution and diplomacy, investigating technological developments, effects of globalisation, social movements, economics, the relationship of resilience to effective deterrence, and the associated complexity of contemporary interdependencies to create a contextualised concept of modern deterrence. Social science and historical methodologies are utilized to gain a comprehensive cross-section of analysis that will reveal the strengths and weaknesses of the use of deterrence as a national security strategy, as well as highlighting the various types of power available for use by the state to create multi-faceted deterrence in order to deal effectively and efficiently with complex emerging challenges.

As a concept, deterrence has launched a thousand books and articles. It has dominated Western strategic thinking for more than four decades. In this important and groundbreaking new book, Lawrence Freedman develops a distinctive approach to the evaluation of deterrence as both a state of mind and a strategic option. This approach is applied to post-cold war crisis management, and the utility and relevance of the concept is addressed in relation to US strategic practice post-9/11, particularly in the light of the apparent preference of the Bush Administration for the alternative concept of pre-emption. The study of deterrence has been hampered by the weight of the intellectual baggage accumulated since the end of the Second World War. Exaggerated notions of what deterrence might achieve were developed, only to be to knocked down by academic critique. In this book, Freedman charts the evolution of the contemporary concept of deterrence, and discusses whether - and how - it still has relevance in today's world. He considers constructivist as well as realist approaches and draws on criminological as well as strategic studies literature to develop a concept of a norms-based, as opposed to an interest-based, deterrence. This book will be essential reading for students of politics and international relations as well as all those interested in contemporary strategic thought.

Conventional Deterrence is a book about the origins of war. Why do nations faced with the prospect of large-scale conventional war opt for or against an offensive strategy? John J. Mearsheimer examines a number of crises that led to major conventional wars to explain why deterrence failed. He focuses first on Allied and German decision making in the years 1939–1940, analyzing why the Allies did not strike first against Germany after declaring war and, conversely, why the Germans did attack the West. Turning to the Middle East, he examines the differences in Israeli and Egyptian strategic doctrines prior to the start of the major conventional conflicts in that region. Mearsheimer then critically assays the relative strengths and weaknesses of NATO and the Warsaw Pact to determine the prospects for conventional deterrence in any future crisis. He is also concerned with examining such relatively technical issues as the impact of precision-guided munitions (PGM) on conventional deterrence and the debate over maneuver versus attrition warfare.Mearsheimer pays considerable attention to questions of military strategy and tactics. Challenging the claim that conventional detrrence is largely a function of the numerical balance of forces, he also takes issue with the school of thought that ascribes deterrence failures to the dominance of "offensive" weaponry. In addition to examining the military consideration underlying deterrence, he also analyzes the interaction between those military factors and the broader political considerations that move a nation to war.

"Deterrence by Denial: Theory and Practice is the first study to focus exclusively on contemporary denial, bridging the theoretical gap that persists between classical deterrence theory and contemporary insecurity. The book significantly advances the scholarship on deterrence by denial with empirically driven and policy-relevant contributions written by leading international scholars of conventional military aggression, missile defense, terrorism and militancy, crime, and cybersecurity. Deterrence by Denial: Theory and Practice is an important and unique book, of interest to scholars of international relations, political science, terrorism and intelligence studies, and cybersecurity, as well as to policy analysts, practitioners, and members of the armed forces and intelligence community"--

“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.

Deterrence is a theory which claims that punishment is justified through preventing future crimes, and is one of the oldest and most powerful theories about punishment. The argument that punishment ought to secure crime reduction occupies a central place in criminal justice policy and is the site for much debate. Should the state deter offenders through the threat of punishment? What available evidence is there about the effectiveness of deterrence? Is deterrence even possible? This volume brings together the leading work on deterrence from the dominant international figures in the field. Deterrence is examined from various critical perspectives, including its diversity, relation with desert, the relation of deterrence with incapacitation and prevention, the role deterrence has played in debates over the death penalty, and deterrence and corporate crime.
