Nuclear weapons have not been used in anger since the United States dropped atomic bombs on Hiroshima and Nagasaki in August 1945. Yet even after the Cold War, the Bomb is still the greatest threat facing humankind. As President Bill Clinton's first secretary of defence, Les Aspin, put it: 'The Cold War is over, the Soviet Union is no more. But the post-Cold War world is decidedly not post-nuclear'. For all the efforts to reduce nuclear stockpiles, the Bomb is here to stay. This Very Short Introduction looks at the science of nuclear weapons and how they differ from conventional weapons. Tracing the story of the nuclear bomb, Joseph Siracusa chronicles the race to acquire the H-bomb, a thermonuclear weapon with revolutionary implications; and the history of early arms control, nuclear deterrence, and non-proliferation. He also tracks the development of nuclear weapons from the origins of the Cold War in 1945 to the end of Moscow-dominated Communism in 1991, and examines the promise and prospect of missile defence, including Ronald Reagan's 'Star Wars' and George W. Bush's National Missile Defence. This third edition includes a new chapter on the development of nuclear weapons and the policies they have generated since the end of the Cold War. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

This book is an authoritative account of the nuclear weapons inspections regime in Iraq from 1991 to 1998. Without a proper understanding of those years, the 2003 US invasion of Iraq after a futile WMD search remain unintelligible. In the 1990s, after adapting to a completely new kind of intrusive inspections with unprecedented access rights, the IAEA discovered and dismantled Iraq's clandestine nuclear weapons program and put in place an efficient monitoring system which could have contained Saddam Hussein's attempts to reconstitute his nuclear programs - had he ever tried to. However, the politicisation of the inspection process led to an end of the inspections in 1998. Based on various sources including inspection reports and other documents in the archive of the IAEA Iraq Action Team at the IAEA headquarters in Vienna, Dismantling the Iraqi Nuclear Programme presents completely new information about the weapons inspection regime in Iraq and offers valuable lessons for future non-proliferation and disarmament cases. The book also draws on discourse from Iraqi scientists, which provides a close look into not only the motivation of involved Iraqis, but also Iraqi concealment mechanisms. This book will be of much interest to students of nuclear proliferation, arms control, Middle Eastern politics, diplomacy, international security and IR.

The UK is one of nine states possessing nuclear weapons. Renewal of the Trident programme would extend Britain’s commitment to so-called nuclear ‘deterrence’ well into the second half of this century, despite treaty obligations and an ‘unequivocal undertaking’ to disarm. With more than 16,000 nuclear weapons stockpiled worldwide, the risk of one going off by accident or design is increasing every day. Wallis in The Truth about Trident explores the issues Trident presents and raises questions like: what would be the impact of their use? How safe are they in the meantime? Are they really necessary? Can we afford them? Are there better alternatives? This book aims to peel back layers of confusion and deceit to reach the truth about Trident.

This Commentary offers detailed background and analysis of the Treaty on the Prohibition of Nuclear Weapons, which was adopted at the UN Headquarters in New York in July 2017. The Treaty comprehensively prohibits the use, development, export, and possession of nuclear weapons. Stuart Casey-Maslen, a leading expert in the field who served as legal adviser to the Austrian Delegation during the negotiations of this Treaty, works through article by article, describing how each provision was negotiated and what it implies for states that join the Treaty. As the Treaty provisions cut across various branches of international law, the Commentary goes beyond a discussion of disarmament to consider the law of armed conflict, human rights, and the law on inter-state use of force. The Commentary examines the relationship with other treaties addressing nuclear weapons, in particular the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Background on the development and possession of nuclear weapons and theories of nuclear deterrence is provided. Particular attention is paid to controversial issues such as assistance for prohibited activities, the meaning of 'threaten to use', and the definition of nuclear explosive devices. Casey-Maslen also considers whether a member of NATO or other nuclear alliance can lawfully become a state party to the Treaty.

Life and Times of the Atomic Bomb takes up the question of how the world found itself in the age of nuclear weapons - and how it has since tried to find a way out of it. Albert I. Berger charts the story of nuclear weapons from their origins through the Atomic Age and the Cold War up through the present day, arguing that an understanding of the history of nuclear weapons is crucial to modern efforts to manage them. This book examines topics including nuclear strategy debates, weapon system procurement decisions, and arms control conferences through the people and leaders who experienced them. Providing a chronological survey, Life and Times of the Atomic Bomb starts with the major scientific discoveries of the late 19th century that laid the groundwork for nuclear development. It then traces the history of nuclear weapons from their inception to the atomic bombings of Hiroshima and Nagasaki in 1945 and the reaction to them by key players on both sides. It continues its narrative into the second half of the twentieth century, and the role of nuclear weapons throughout the Cold War, engaging in the debate over whether nuclear weapons are an effective deterrent. Finally, the closing chapters consider the atomic bomb's place in the modern world and the transformation of warfare in an age of advanced technology. This clear and engaging survey will be invaluable reading for students of the Cold War and twentieth-century history.

This book explores the history of the nuclear nonproliferation dialogue between Russia (USSR) and the United States. By looking into the particulars of bilateral cooperation on NPT, Cooperative Threat Reduction program, arms control, and other issues, the authors offer lessons to be learned in preventing nuclear confrontations in the future. The book has been prepared in coordination between Russian and American scholars and experts and is a result of a series of Track 2.5 events devoted to restoring the nonproliferation cooperation between Russia and the United States. Covering all the aspects of the bilateral partnership since 1960 until today, this book will interest scholars of great power conflicts and nonproliferation. The workshop and the consequent work on the monograph became possible thanks to generous organizational & financial support from Centre russe d`etudes politiques (Geneva) and the Center for Policy Studies in Russia (Monterey, USA).

Presidential nominations in the United States can sometimes seem like a media circus, over-hyped and overly speculative. Even informed citizens might be tempted to tune them out. Yet understanding the process, one distinct to American politics, is crucial for civic participation. If presidential elections are about who will lead the nation, presidential nominations are about who appears on the ballot. This concise and coherent Citizen's Guide examines who has power in presidential nominations and how this affects who we as citizens choose to nominate, and ultimately to sit in the Oval Office. Political scientist Wayne Steger defines the nominating system as a tension between an "insider game" and an "outsider game." He explains how candidates must appeal to a broad spectrum of elected and party officials, political activists, and aligned groups in order to form a winning coalition within their party, which changes over time. Either these party insiders unify early behind a candidate, effectively deciding the nominee before anyone casts a vote, or they are divided and the nomination is determined by citizens voting in the caucuses and primaries. Steger portrays how shifts in party unity and the participation of core party constituencies affect the options presented to voters. Amidst all this, the candidate still matters. Primaries with one strong candidate look much different than those with a field of weaker ones. By clearly addressing the key issues, past and present, of presidential nominations, Steger's guide will be informative, relevant, and accessible for students and general readers alike.

In June 1994 the United States went to the brink of war with North Korea. With economic sanctions impending, President Bill Clinton approved the dispatch of substantial reinforcements to Korea, and plans were prepared for attacking the North's nuclear weapons complex. The turning point came in an extraordinary private diplomatic initiative by former President Jimmy Carter and others to reverse the dangerous American course and open the way to a diplomatic settlement of the nuclear crisis.

Few Americans know the full details behind this story or perhaps realize the devastating impact it could have had on the nation's post-Cold War foreign policy. In this lively and authoritative book, Leon Sigal offers an inside look at how the Korean nuclear crisis originated, escalated, and was ultimately defused. He begins by exploring a web of intelligence failures by the United States and intransigence within South Korea and the International Atomic Energy Agency. Sigal pays particular attention to an American mindset that prefers coercion to cooperation in dealing with aggressive nations. Drawing upon in-depth interviews with policymakers from the countries involved, he discloses the details of the buildup to confrontation, American refusal to engage in diplomatic give-and-take, the Carter mission, and the diplomatic deal of October 1994.

In the post-Cold War era, the United States is less willing and able than before to expend unlimited resources abroad; as a result it will need to act less unilaterally and more in concert with other nations. What will become of an American foreign policy that prefers coercion when conciliation is more likely to serve its national interests? Using the events that nearly led the United States into a second Korean War, Sigal explores the need for policy change when it comes to addressing the challenge of nuclear proliferation and avoiding conflict with nations like Russia, Iran, and Iraq. What the Cuban missile crisis was to fifty years of superpower conflict, the North Korean nuclear crisis is to the coming era.

This collection of essays offers a fresh look at the 1970s, the crucial decade when the nuclear non-proliferation regime took shape. Exploring a broad array of newly declassified archival sources from different countries across the globe, and moving freely across methodological and national barriers, historians from Europe, North and South America, Asia and Africa discuss the making of the global nuclear order from truly international and transnational perspectives. The result is a fascinating and innovative volume which will remain an essential reference for historians of the nuclear age, of the cold war, and more generally of the evolution of the international system in the second half of the twentieth century. The chapters in this book were originally published as a special issue of The International History Review.

The primary mission assigned to the British Army from the 1950s until the end of the Cold War was deterring Soviet aggression in Europe by demonstrating the will and capability to fight with nuclear weapons in defence of NATO territory. This 'surreal' mission was unlike any other in history, and raised a number of conceptual and practical difficulties. This comprehensive study observes how the British Army imagined nuclear war, and how it planned to fight it. Using new archival sources, Simon J. Moody analyses British thinking about tactical nuclear weapons, the role of the Army within NATO strategy, the development of theories of tactical nuclear warfare, how nuclear war was taught at the Staff College, the role of operational research, and the evolution of the Army's nuclear war-fighting doctrine. He argues that the British Army possessed the intellectual capacity for organisational adaptation, but that it displayed a cognitive dissonance about some of the more uncomfortable realities of nuclear war.

Political Fallout is the story of one of the first human-driven, truly global environmental crises—radioactive fallout from nuclear weapons testing during the Cold War—and the international response. Beginning in 1945, the United States, Britain, and the Soviet Union detonated hundreds of nuclear weapons in the atmosphere, scattering a massive amount of radioactivity across the globe. The scale of contamination was so vast, and radioactive decay so slow, that the cumulative effect on humans and the environment is still difficult to fully comprehend. The international debate over nuclear fallout turned global radioactive contamination into an environmental issue, eventually leading the nuclear superpowers to sign the landmark Partial Test Ban Treaty (PTBT) in 1963. Bringing together environmental history and Cold War history, Toshihiro Higuchi argues that the PTBT, originally proposed as an arms control measure, transformed into a dual-purpose initiative to check the nuclear arms race and radioactive pollution simultaneously. Higuchi draws on sources in English, Russian, and Japanese, considering both the epistemic differences that emerged in different scientific communities in the 1950s and the way that public consciousness around the risks of radioactive fallout influenced policy in turn. Political Fallout addresses the implications of science and policymaking in the Anthropocene—an era in which humans are confronting environmental changes of their own making.

James Bond's amazing gadgets reveal both enthusiasm about technology and fear of its potential ramifications. The popularity of the 007 franchise depends on a seductive formula of sex, violence, and snobbery. Much of its appeal, too, lies in its gadgets: slick, somewhat improbable technological devices that give everyone's favorite secret agent the edge over his adversaries. In Equipping James Bond, Andre Millard chronicles a hundred-year history of espionage technology through the lens of Ian Fleming's infamous character and his ingenious spyware. Beginning with the creation of MI6, the British secret service, Millard traces the development of espionage technology from the advanced weaponry of the nineteenth century to the evolving threat of computer hacking and surveillance. Arguing that the gadgets in the books and films articulate the leading edge of technological awareness at the time, Millard describes how Bond goes from protecting 1950s England from criminal activity to saving a world threatened by nuclear bombs, poison gas, and attacks from space. As a modern and modernizing hero, Bond has to keep up with the times. His film franchise is committed to equipping both Bond and his adversaries with the latest technological gadgets. Simultaneously, Millard stresses, the villains and threats that Bond faces embody contemporary fears about the downside of technological change. Taking a wide-ranging look at factual (and fictional) technology, Millard views the James Bond universe as evidence for popular perceptions of technological development as both inevitably progressive and apocalyptically threatening.

Fifty years into the nuclear non-proliferation treaty (NPT) regime, the risks of nuclear war, terrorism, and the threat of further proliferation remain. A lack of significant progress towards disarmament will cast doubt upon the viability of the NPT. By recognizing that certain fissile materials are essential to every nuclear weapon and that controlling their usage provides the foundation for international efforts to limit their spread, this book presents a comprehensive framework for nuclear disarmament. Based upon phased reductions, Shea provides a mechanism for the disposal of weapon-origin fissile material and controls on peaceful nuclear activities and non-explosive military uses. He explores the technological means for monitoring and verification, the legal arrangements required to provide an enduring foundation, and a financial structure which will enable progress. This book will be invaluable to professional organizations, arms control NGOs, government officials, scientists, and politicians. It will also appeal to academics and postgraduate researchers working on security studies, disarmament diplomacy and the politics and science of verification.

This new Handbook is a comprehensive examination of the rich and complex issues of nuclear proliferation in the early 21st century. The future of the decades-long effort to prevent the further spread of weapons of mass destruction is at a crossroads today. If international nonproliferation efforts are to be successful, an integrated, multi-tiered response will almost certainly be necessary. A serious, thorough, and clear-eyed examination of the range of threats, challenges, and opportunities facing the international community is a necessary first step. This Handbook, which presents the most up-to-date analysis and policy recommendations on these critical issues by recognized, leading scholars in the field, intends to provide such an examination. The volume is divided into three major parts: Part I presents detailed threat assessments of proliferation risks across the globe, including specific regions and countries. Part II explains the various tools developed by the international community to address these proliferation threats. Part III addresses the proliferation risks and political challenges arising from nuclear energy production, including potential proliferation by aspiring states and nonstate groups. This Handbook will be of great interest to students and practitioners of nuclear proliferation, arms control, global governance, diplomacy, and global security and IR general.

'You couldn't make these stories up: yet they're true, and Lewis does the memory of these extraordinary men full justice in a tale that is both heart-stopping and moving' Evening Standard 'Suicidal bravery, untold moral courage and awe-inspiring survival. An utterly compelling read' Bear Grylls From the bestselling author of true military classics ZERO SIX BRAVO, THE NAZI HUNTERS and CHURCHILL'S SECRET WARRIORS In the Spring of 1940, as Britain reeled from defeats on all fronts and America seemed frozen in isolation, one fear united the British and American leaders like no other: the Nazis had stolen a march on the Allies towards building the atomic bomb. So began the hunt for Hitler's nuclear weapons - nothing else came close in terms of priorities. It was to be the most secret war of those wars fought amongst the shadows. The highest stakes. The greatest odds. Prior to the outbreak of the war the massive German chemicals conglomerate I.G. Farben - the future manufacturers of Zyklon-B, the gas used in the Nazi concentration camps - had started producing bulk supplies of deuterium oxide - heavy water - at the remote Norwegian plant of Vemork. This was the central target of three separate missions - Operations GROUSE, FRESHMAN and GUNNERSIDE - over the ensuing four years. As Churchill commented: 'The actual facts in many cases were equal to the most fantastic inventions of romance and melodrama. Tangle with tangle, plot and counter-plot, ruse and treachery, cross and double-cross, true agent, false agent, double agent, gold and steel, the bomb, the dagger and the firing party were interwoven in a texture so intricate as to be incredible yet true.' Damien Lewis's new bestseller intercuts the hunt for the scientists, the raw materials and the plant, with the cloak and dagger intelligence game being played in the shadows. This relied in part on ENIGMA intercepts to guide the SOE's hand. Lewis delves into some of the most extraordinarily inventive and Machiavellian innovations at the SOE, and their related research and training schools, whereby the enemy were tricked, deceived, framed, blackmailed and double and triple-crossed, all in the name of stopping the Reich from getting the bomb.

Nuclear proliferation in the Middle East remains an issue of concern. Saudi Arabia's actions will largely rest on Iran's decisions, and discussions and preparations within Saudi Arabia would suggest that it is ready to react to potential shifts in the region's nuclear powers. Saudi Arabia and Nuclear Weapons uses an "inside out" approach that emphasises the Saudis' own national interests in relation to the nuclear threat, and their understanding of the role of nuclear weapons in defense, foreign policy and the concept of deterrence. It is the first study with comprehensive use of the local Arabic language military and civilian media to provide this understanding of official thinking and policy. The Saudi case study is contextualised against the prevailing proliferation models, to conclude that the Saudi case shares both commonalities and elements of uniqueness with other proliferation cases, implying the need for a 'multi-causal' approach. Its comparative analysis also suggests potential implications applicable more broadly to the issue of nuclear proliferation. A comprehensive study of Saudi Arabia's attitude to nuclear weapons, this book offers an exploration of nuclear proliferation that would interest students, scholars and policymakers working in Middle East studies, as well as Military and nuclear proliferation studies.

If the nuclear weapons club were to further expand, would America s democratic allies in Northeast Asia be among the next entrants? Japan, South Korea and Taiwan all have robust civilian nuclear energy programmes that make them virtual nuclear powers according to many analysts. All three once pursued nuclear weapons and all face growing security threats from nuclear-armed adversaries. But will they or rather, under what circumstances might they? This book analyses these past nuclear pursuits and current proliferation drivers. In explaining the nuclear technology that the three now possess, it considers how long it would take each to build a nuclear weapon if such a fateful decision were made. Although nuclear dominoes Northeast Asia cannot be ruled out, the author does not predict such a scenario. Unlike when each previously went down a nuclear path, democracy and a free press now prevail as barriers to building nukes in the basement. Reliance on US defence commitments is a better security alternative -- as long as such guarantees remain credible, an issue that is also assessed. But extended deterrence is not a tight barrier to proliferation of sensitive nuclear technologies. Nuclear hedging by its Northeast Asian partners will challenge Washington s nuclear diplomacy.

If you think you know the full story of Trinity Site, birthplace of the atomic bomb, you don't. Robert Oppenheimer didn't built the bomb, it was hand made by engineers, chemists and young physicists in their twenties and many not yet having earned a degree. The first atomic bomb was originally planned as a backup device, a weapon not then currently achievable. The Trinity Site was bombed several times by US aircraft while one Manhattan Project facility was struck by a Japanese weapon. Many commonly held ""facts"" are actually at best unsubstantiated and here for the first time is a book that speaks of a pivot point in history from the point of view of the men who served in the American desert. Five years of research using original letters, memos and reports, many only recently declassified from those involved bring a fresh perspective on the events now approaching it's 75th anniversary.

This volume examines the causes and consequences of nuclear postures and nonproliferation policies. The real-world importance of nuclear weapons has led to the production of a voluminous scholarly literature on the causes and consequences of nuclear weapons proliferation. Missing from this literature, however, is a more nuanced analysis that moves beyond a binary treatment of nuclear weapons possession, to an exploration of how different nuclear postures and nonproliferation policies may influence the proliferation of nuclear weapons and subsequent security outcomes. This volume addresses this deficit by focusing on the causes and consequences of nuclear postures and nonproliferation policies. It is the aim of this book to advance the development of a new empirical research agenda that brings systematic research methods to bear on new dimensions of the nuclear weapons phenomenon. Prior to the contributions in this volume, there has been little evidence to suggest that nuclear postures and policies have a meaningful impact on the spread of nuclear weapons or security outcomes. This book brings together a new generation of scholars, advancing innovative theoretical positions, and performing quantitative tests using original data on nuclear postures, nonproliferation policies, and WMD proliferation. Together, the chapters in this volume make novel theoretical, empirical, and methodological contributions to the field of nuclear weapons proliferation. This book will be of much interest to students of nuclear proliferation, international relations and security studies.

Epistemic communities represent networks of knowledge-based experts that help articulate cause-and-effect relationships of complex problems, define the self-interests of a state, or formulate specific policies for state decision makers. However, the role of these scientists and knowledgeable professionals in nuclear policy formulation is poorly understood. Thoroughly documented and making excellent use of source material, Politics and the Bomb provides refreshingly new empirical evidence and theoretical analysis of the importance of scientists and experts behind the creation of new non-proliferation agreements. Simply not another book on nuclear proliferation, Sara Z. Kutchesfahani explores the differences in the emergence, composition, and influence mechanisms of the epistemic communities behind the nuclear non-proliferation policy formulation in Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials (ABACC) and the Nunn-Lugar Cooperative Threat Reduction (CTR) Program. In doing so she eloquently demonstrates how the role of these non-proliferation experts lead to the possibility of creating more effective non-proliferation policies in the future and hints at the need to sustain non-proliferation epistemic communities in all countries that can provide input to the global proliferation problem until it is solved.

Between December 1943 and August 1944, Franklin Delano Roosevelt and Winston Churchill ignited the Cold War, a superpower rivalry that would dominate the world over half a century, by building an atomic bomb and excluding their Russian allies. Peter Watson tells the pulse-pounding story of how two atomic physicists tried to counter this in two very different ways. While Niels Bohr sought to convince President Roosevelt and Prime Minister Churchill to share their nuclear knowledge with Joseph Stalin, nuclear scientist Klaus Fuchs, a German Communist emigre to Britain, was leaking atomic secrets to the Soviets in a rival attempt to ensure parity between the superpowers. Neither succeeded in preventing the World War II allies from unleashing the atom bomb on the world. Fallout proves that the atomic bomb was not needed, and was made as a result of a series of flawed decisions. The Americans did not tell the UK that the atomic research was compromised by Soviet spies; the British did not tell the Americans that in 1943 they knew for sure that Germany did not have a nuclear bomb program. Neither country admitted to the scientists developing the bomb that it would never be used to counter the (non-existent) German nuclear threat. Had the scientists known, many of them would have refused to complete work on the bomb. This story shows how politicians fatally failed to understand the nature of atomic science and, in so doing, exposed the world needlessly to great danger, a danger that is still very much with us.

The 1968 Nuclear Non-proliferation Treaty has proven the most complicated and controversial of all arms control treaties, both in principle and in practice. Statements of nuclear-weapon States from the Cold War to the present, led by the United States, show a disproportionate prioritization of the non-proliferation pillar of the Treaty, and an unwarranted underprioritization of the civilian energy development and disarmament pillars of the treaty. This book argues that the way in which nuclear-weapon States have interpreted the Treaty has laid the legal foundation for a number of policies related to trade in civilian nuclear energy technologies and nuclear weapons disarmament. These policies circumscribe the rights of non-nuclear-weapon States under Article IV of the Treaty by imposing conditions on the supply of civilian nuclear technologies. They also provide for the renewal and maintaintenance, and in some cases further development of the nuclear weapons arsenals of nuclear-weapon States. The book provides a legal analysis of this trend in treaty interpretation by nuclear-weapon States and the policies for which it has provided legal justification. It argues, through a close and systematic examination of the Treaty by reference to the rules of treaty interpretation found in the 1969 Vienna Convention on the Law of Treaties, that this disproportionate prioritization of the non-proliferation pillar of the Treaty leads to erroneous legal interpretations in light of the original balance of principles underlying the Treaty, prejudicing the legitimate legal interests of non-nuclear-weapon States.
