Since the Hiroshima and Nagasaki attacks, no state has unleashed nuclear weapons. What explains this? According to the author, the answer lies in a prohibition inherent in thetradition of non-use, a time-honored obligation that has been adhered to by all nuclear statesthanks to a consensus view that use would have a catastrophic impact on humankind, the environment, and the reputation of the user.The book offers an in-depth analysis of the nuclear policies of the U.S., Russia, China, the UK, France, India, Israel, and Pakistan and assesses the contributions of these states to the rise and persistence of the tradition of nuclear non-use. It examines the influence of the tradition on the behavior of nuclear and non-nuclear states in crises and wars, and explores the tradition's implications for nuclear non-proliferation regimes, deterrence theory, and policy. And it concludes by discussing the future of the tradition in the current global security environment. T.V. Paul, a distinguished academic . . . has made a valuable contribution to exploring the historical experience of the non-use of nuclear weapons and the challenges now faced globally. Paul has written an interesting and useful book. He highlights the continuing and perhaps increasing dangers of nuclear use and the importance of maintaining the tradition of non-use. This is a debate that has been neglected and Paul puts it firmly back on the agenda both for students of strategic studies and practitioners involved in maintaining internationals security in a dangerous world. Paul has produced an excellent book. The central argument that a tradition of non-use has restrained the use of nuclear weapons is well-developed and largely convincing. Although the extent of this influence is, of course, debatable, Paul succeeds in exploring the historical influence and broader implications of the tradition. This book therefore makes an important contribution to the growing body of literature considering the nonl£!
