The proliferation of advanced weapons to volatile regions of the world has become a major issue in the post Cold War era. It was thought that no Third World nation could ever pose a technologically-based threat to the great powers by acquiring advanced weaponry. But this has proved to be wrong. The Persian Gulf War changed the worldwide perception of the spread of ballistic missiles to countries like Iraq. Access to a new type of weapon--cruise missiles--poses an even greater threat. With technology that is accessible, affordable, and relatively simple to produce, Third World countries could acquire highly accurate, long-range cruise missile forces to escalate local conflicts and threaten the forces and even the territories of the industrial powers. This book is a warning to policymakers. It is not too late to confront the realities of cruise missile proliferation and to devise international responses that could contain the worst possible consequences. Carus proposes a new regime of technology controls, security-building measures, and conflict resolution that need to be considered, and acted on, by policymakers and international relations experts everywhere.

Drawing upon anthropology, biology, psychology, sociology, and literature, this brilliant insight into why men go to war traces the changes that have occurred in weapons and tactics since prehistoric times. Robert O'Connell demonstrates how the technology unleashed during World War I made human qualities almost irrelevant to the conduct of war, until now, in the nuclear age, humanity has become subservient to the weapons it has made.

The nuclear freeze movement grew more quickly than even the most optimistic activists thought possible, as large numbers of Americans became convinced that there was something wrong with United States defense policy and that they could do something about it. This analysis provides the first comprehensive history of the nuclear freeze movement, approaching it from three distinct perspectives. Changes in the politics and policy of nuclear weapons created an opportunity for a dissident movement. Intermediating forces in American politics influenced the situation. The efforts of activists and organizations to build a protest movement and their interaction with American political institutions provide the third perspective. "A Winter of Discontent" addresses both the broad spectrum of movement activity and the political context surrounding it.

The text explores the challenge of the nuclear freeze movement to the content of United States national security policy and the policy making process. By analyzing the freeze, a theoretical framework for understanding the origins, development and potential political influence of other protest movements in the United States can be developed. The book also strives to integrate analysis of peace movements into an understanding of the policy context in which they emerge. This volume is essential for courses in social movements, strategic policy, American politics and political sociology. Antinuclear freeze activists and students of peace studies will also find this work invaluable.

Advocating nuclear war, attempting communication with dolphins and taking an interest in the paranormal and UFOs, there is perhaps no greater (or stranger) cautionary tale for the Left than that of Posadism. Named after the Argentine Trotskyist J. Posadas, the movement's journey through the fractious and sectarian world of mid-20th century revolutionary socialism was unique. Although at times significant, Posadas' movement was ultimately a failure. As it disintegrated, it increasingly grew to resemble a bizarre cult, detached from the working class it sought to liberate. The renewed interest in Posadism today - especially for its more outlandish fixations - speaks to both a cynicism towards the past and nostalgia for the earnest belief that a better world is possible. Drawing on considerable archival research, and numerous interviews with ex- and current Posadists, I Want to Believe tells the fascinating story of this most unusual socialist movement and considers why it continues to capture the imaginations of leftists today.

Helps us to better understand the dangers of U.S. nuclear strategy, and reminds us that it is a strategy we can resist.

On 30 October 1961, the Union of Soviet Socialist Republics (USSR/Soviet Union) conducted a live test of the most powerful nuclear weapon ever created. Codenamed 'Ivan', and known in the West as the 'Tsar Bomba', the RDS-202 hydrogen bomb was detonated at the Sukhoy Nos cape of Severny Island, Novaya Zemla archipelago, in the Barents Sea. The Tsar Bomba unleashed about 58 megatons of TNT, creating a 8-kilometre/5-mile-wide fireball and then a mushroom that peaked at an altitude of 95 kilometres (59 miles). The shockwave created by the RDS-202 eradicated a village 55 kilometres (34 miles) from ground zero, caused widespread damage to nature to a radius of dozens of kilometres further away, and created a heat wave felt as far as 270 kilometres (170 miles) distant. And still, this was just one of 45 tests of nuclear weapons conducted in the USSR in October 1961 alone. Between 1949 and 1962, the Soviets set off 214 nuclear bombs in the open air. Dozens of these were released from aircraft operated by specialised test units. Equipped with the full range of bombers - from the Tupolev Tu-4, Tupolev Tu-16, to the gigantic Tu-95 - the units in question were staffed by men colloquially known as the 'deaf-and-dumb': people sworn to utmost secrecy, living and serving in isolation from the rest of the world. Frequently operating at the edge of the envelope of their specially modified machines while test-releasing weapons with unimaginable destructive potential, several of them only narrowly avoided catastrophe. Richly illustrated with authentic photographs and custom-drawn colour profiles, Dropping the Big Ones is the story of the aircrews involved and their aircraft, all of which were carefully hidden not only by the Iron Curtain, but by a thick veil of secrecy for more than half a century.

DOD spends billions of dollars annually to sustain its weapon systems to support current and future operations. The Air Force and Navy are operating many of their fixed-wing aircraft well beyond their original designed service lives and therefore are confronted with sustainment challenges. Chapter 1 examines the trends in availability and O&S costs for selected Air Force and Navy fixed-wing aircraft since fiscal year 2011, including whether they met availability goals, and assesses the extent that the departments documented sustainment strategies, reviewed sustainment metrics, and implemented plans to improve aircraft availability. Software is integral to the operation and functionality of DOD equipment, platforms, and weapon systems, including tactical and combat vehicles, aircraft, ships, submarines, and strategic missiles. Chapter 2 examines the extent to which (1) DOD has policies and organizations in place to manage the sustainment of operational system software for weapon systems; and (2) DOD and the military departments track costs to sustain weapon system software. The Department of Defense (DOD) and the Department of Energy (DOE) are undertaking an extensive, multifaceted effort to sustain and modernize U.S. nuclear weapons capabilities, including the nuclear weapons stockpile; the research and production infrastructure; delivery systems; and the nuclear command, control, and communications (NC3) system. Chapter 3 presents observations on the extent to which the FY 2018 joint report provides accurate and complete information about nuclear sustainment and modernization budget estimates and related budget estimating methodologies. The Department of Defense and NNSA have sought for nearly a decade to replace the capabilities of the aging W78 nuclear warhead used by the U.S. Air Force. Chapter 4 describes NNSA's steps in key early planning areas ... including program management, technology assessment, and coordination with facilities and capabilities ... to prepare to restart a program to replace the W78. Responsibility for U.S. nuclear weapons resides in both the Department of Defense (DOD) and the Department of Energy (DOE). DOD develops, deploys, and operates the missiles and aircraft that deliver nuclear warheads. It also generates the military requirements for the warheads carried on those platforms. Chapter 5 focuses on the facilities managed by the DOE and its semiautonomous National Nuclear Security Administration (NNSA). The Trump Administration's Nuclear Posture Review includes plans for the United States to deploy two new types of nuclear weapons "to enhance the flexibility and responsiveness of U.S. nuclear forces." Chapter 6 highlights that these weapons represent a response to Russia's deployment of a much larger stockpile of lower-yield nonstrategic nuclear weapons.

Environmental tragedies such as Chernobyl and the "Exxon Valdez" remind us that catastrophic accidents are always possible in a world full of hazardous technologies. Yet, the "apparently" excellent safety record with nuclear weapons has led scholars, policy-makers, and the public alike to believe that nuclear arsenals can serve as a secure deterrent for the foreseeable future. In this provocative book, Scott Sagan challenges such optimism. Sagan's research into formerly classified archives penetrates the veil of safety that has surrounded U.S. nuclear weapons and reveals a hidden history of frightening "close calls" to disaster.

The atomic bombs dropped on Hiroshima and Nagasaki in August of 1945 unleashed a force as mysterious as it was deadly--radioactivity. In 1946, the United States government created the Atomic Bomb Casualty Commission (ABCC) to serve as a permanent agency in Japan with the official mission of studying the medical effects of radiation on the survivors. The next ten years saw the ABCC's most intensive research on the genetic effects of radiation, and up until 1974 the ABCC scientists published papers on the effects of radiation on aging, life span, fertility, and disease.
"Suffering Made Real" is the first comprehensive history of the ABCC's research on how radiation affected the survivors of the atomic bomb. Arguing that Cold War politics and cultural values fundamentally shaped the work of the ABCC, M. Susan Lindee tells the compelling story of a project that raised disturbing questions about the ethical implications of using human subjects in scientific research.
How did the politics of the emerging Cold War affect the scientists' biomedical research and findings? How did the ABCC document and publicly present the effects of radiation? Why did the ABCC refuse to provide medical treatment to the survivors? Through a detailed examination of ABCC policies, archival materials, the minutes of committee meetings, newspaper accounts, and interviews with ABCC scientists, Lindee explores how political and cultural interests were reflected in the day-to-day operations of this controversial research program.
Set against a period of conflicting views of nuclear weapons and nuclear power, "Suffering Made Real" follows the course of a politically charged research program and reveals indetail how politics and cultural values can shape the conduct, results, and uses of science.

The International Atomic Energy Agency (IAEA)plays a crucial role in supporting U.S. nuclear non-proliferation goals through its safeguards and nuclear security programs. The Department of State (State) co-ordinates the United States' financial and policy relationship with IAEA. IAEA's safeguards program is designed to detect and deter the diversion of nuclear material for non-peaceful purposes, while the agency's nuclear security program assists countries in improving the physical protection of their nuclear material and facilities. IAEA plans to create an international fuel bank to guarantee the supply of fuel for civilian nuclear power programs. This book examines any challenges that IAEA faces in carrying out its safeguards program; any limitations regarding the nuclear security program; and the status of IAEA's planned nuclear fuel bank.

"The most likely site for a nuclear war is the Indian subcontinent, but we have little understanding of India's nuclear program. This will change with George Perkovich's fascinating and important study. It is informed, free from bias, and a great read as well."--Robert Jervis, Adlai E. Stevenson Professor of International Politics, Columbia University

"George Perkovich has written a comprehensive and thoughtful book on one of the most troubling security problems of the day--the introduction of nuclear weapons to the already dangerous confrontation between India and Pakistan." --William J. Perry, Professor, Stanford University, Former US Secretary of Defense

"George Perkovich's India's Nuclear Bomb is an authoritative account in Indian decision-making. I have found no other statement as comprehensive and persuasive. It provides unique insights into Indian politics and is an invaluable contribution to American thinking about nonproliferation." --Frank G. Wisner, U.S. Ambassador to India, 1994-1997

"With a great deal of empathy and understanding of the Indian psyche, George Perkovich leads us through contradictory perceptions of events to give us a sense of the evolution of nuclear decision making in India. What emerges is a highly nuanced and sensitive narration of the complex interaction between domestic and external factors that led to the nuclear tests of May, 1998 and the shattering of a number of Indian and international myths about nuclear weapons and their role in global politics." --K. Subrahmanyam, Consulting Editor The Times of India and The Economic Times, Chairman, Indian National Security Advisory Board

"George Perkovich's book is one I wish I had written. India'sNuclear Bomb appears at a critical moment in global nuclear history, and it will have an important impact on the current policy debate in the United States, India, and Pakistan, as well as on the future histories of Indian politics and international security policy." --Stephen Cohen, Senior Fellow, Brookings Institution, Washington, DC

Until now, there has been no detailed account of Israel's nuclear history. Previous treatments of the subject relied heavily on rumors, leaks, and journalistic speculations. But with "Israel and the Bomb, " Avner Cohen has forged an interpretive political history that draws on thousands of American and Israeli government documents -- most of them recently declassified and never before cited -- and more than one hundred interviews with key individuals who played important roles in this story. Cohen reveals that Israel crossed the nuclear weapons threshold on the eve of the 1967 Six-Day War, yet it remains ambiguous about its nuclear capability to this day. What made this posture of "opacity" possible, and how did it evolve?

Cohen focuses on a two-decade period from about 1950 until 1970, during which David Ben-Gurion's vision of making Israel a nuclear-weapon state was realized. He weaves together the story of the formative years of Israel's nuclear program, from the founding of the Israeli Atomic Energy Commission in 1952, to the alliance with France that gave Israel the sophisticated technology it needed, to the failure of American intelligence to identify the Dimona Project for what it was, to the negotiations between President Nixon and Prime Minister Meir that led to the current policy of secrecy. Cohen also analyzes the complex reasons Israel concealed its nuclear program -- from concerns over Arab reaction and the negative effect of the debate at home to consideration of America's commitment to nonproliferation.

"Israel and the Bomb" highlights the key questions and the many potent issues surrounding Israel's nuclear history. This book will be a critical resource for students of nuclear proliferation, Middle East politics, Israeli history, and American-Israeli relations, as well as a revelation for general readers.

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.

In the spring of 1945 the Allies arrested the physicists they believed had worked on the German nuclear programme during the war. Interned in an English country house, their conversations were secretly recorded. MI6's Operation Epsilon sought to determine how close Nazi Germany had come to building an atomic bomb. It was in this remote setting - Farm Hall, near Cambridge - that the German physicists first heard of the bombing ofHiroshima. August 6 1945 was a night that changed the course of history. The terrible weapon unleashed on Japan caused unprecedented destruction and loss of life. That the Allies had such a weapon at their disposal came as a great shock to the German scientists who had worked under the assumption that the Allies knew nothing of nuclear fission. This is the story of the wartime race to develop an atomic bomb, and the genius, guilt, complicity and hubris of Nobel Prize-winning scientists working to create a weapon that would undoubtedly have won the war for the Germans.

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.

In Resurrecting Nagasaki, Chad R. Diehl explores the genesis of narratives surrounding the atomic bombing of August 9, 1945, by following the individuals and groups who contributed to the shaping of Nagasaki City's postwar identity. Municipal officials, survivor-activist groups, the Catholic community, and American occupation officials all interpreted the destruction and reconstruction of the city from different, sometimes disparate perspectives. Diehl's analysis reveals how these atomic narratives shaped both the way Nagasaki rebuilt and the ways in which popular discourse on the atomic bombings framed the city's experience for decades.

There was an expectation that the end of the Cold War would herald a new era of peace and stability in which the importance of nuclear weapons was marginalized. Instead, we have been left with a fractious, inter-dependent international community rife with ethnic and religious tension and unbound by super-power competition. The challenges of climate change, demographic shifts and resource competition have further altered the security environment. As if this were not enough, nuclear proliferation is once again at the top of the international agenda.

In the last decade the Nuclear Proliferation Treaty (NPT) has been challenged from within by Iraq, Iran and Libya while India s, Pakistan s and North Korea's nuclear weapon capabilities are threatening the non-proliferation norm from without. The new proliferators are predominantly, but not exclusively, aggressive, unstable and authoritarian regimes, considered by many in the international community to be outside the constraints of international normative behaviour. Some have even been labelled outlaw, or rogue states. Although inter-continental nuclear war is not presently considered a danger, the increased number of nuclear weapons states combined with the nature of those states and the strategic environment in which they exist makes the possibility of a lesser nuclear exchange potentially much greater. In parallel, the 9/11 atrocities raised fears of the prospect of apocalyptic terrorists acquiring nuclear weapons. Indications that the NPT is failing to rise to the challenge have resulted in policy decisions that have arguably reversed both the disarmament and non-proliferation norms.

This volume delves deep into the changing global nuclear landscape. The chapters document the increasing complexity of the global nuclear proliferation dynamic and the inability of the international community to come to terms with a rapidly changing strategic milieu. The future, in all likelihood, will be very different from the past, and the chapters in this volume develop a framework that may helps gain a better understanding of the forces that will shape the nuclear proliferation debate in the years to come.

Part I examines the major thematic issues underlying the contemporary discourse on nuclear proliferation.

Part II gives an overview of the evolving nuclear policies of the five established nuclear powers: the USA, Russia, the United Kingdom, France and the People's Republic of China.

Part III looks at the three de facto nuclear states: India, Pakistan and Israel.

Part IV examines two problem states' in the proliferation matrix today: Iran and North Korea.

Part V sheds light on an important issue often ignored during discussions of nuclear proliferation cases where states have made a deliberate policy choice of either renouncing their nuclear weapons programme, or have decided to remain a threshold state. The cases of South Africa, Egypt and Japan will be the focus of this section.

The final section, Part VI, will examine the present state of the global nuclear non-proliferation regime, which most observers agree is currently facing a crisis of credibility. The three pillars of this regime the NPT, the Comprehensive Test Ban Treaty and the Fissile Material Cut-Off Treaty will be analyzed.

In this concise account of why America used atomic bombs against Japan in 1945, J. Samuel Walker analyzes the reasons behind President Truman's most controversial decision. Delineating what was known and not known by American leaders at the time, Walker evaluates the options available for ending the war with Japan. In this new edition, Walker incorporates a decade of new research--mostly from Japanese archives only recently made available--that provides fresh insight on the strategic considerations that led to dropping the bomb. From the debate about whether to invade or continue the conventional bombing of Japan to Tokyo's agonizing deliberations over surrender and the effects of both low- and high-level radiation exposure, Walker continues to shed light on one of the most earthshaking moments in history. Rising above an often polemical debate, the third edition presents an accessible synthesis of previous work and new research to help make sense of the events that ushered in the atomic age.

Who were the three men the American and Soviet superpowers exchanged at Berlin's Glienicke Bridge and Checkpoint Charlie in the first and most legendary prisoner exchange between East and West? "Bridge of Spies" vividly traces their paths to that exchange on February 10, 1962, when their fate helped to define the conflicts and lethal undercurrents of the most dangerous years of the Cold War.
"Bridge of Spies" is the true story of three extraordinary characters - William Fisher, alias Rudolf Abel, a British born KGB agent arrested by the FBI in New York City and jailed as a Soviet superspy for trying to steal America's most precious nuclear secrets; Gary Powers, the American U-2 pilot who was captured when his plane was shot down while flying a reconnaissance mission over the closed cities of central Russia; and Frederic Pryor, a young American graduate student in Berlin mistakenly identified as a spy, arrested and held without charge by the Stasi, East Germany's secret police.
By weaving the three strands of this story together for the first time, Giles Whittell masterfully portrays the intense political tensions and nuclear brinkmanship that brought the United States and Soviet Union so close to a hot war in the early 1960s. He reveals the dramatic lives of men drawn into the nadir of the Cold War by duty and curiosity, and the tragicomedy of errors that eventually induced Khrushchev to send missiles to Castro. Two of his subjects -- the spy and the pilot -- were the original seekers of weapons of mass destruction. The third, an intellectual, fluent in German, unencumbered by dependents, and researching a Ph.D. thesis on the foreign trade system of the Soviet bloc, seemed to the Stasi precisely the sort of person the CIA should have been recruiting. He was not. In over his head in the world capital of spying, he was wrongly charged with espionage and thus came to the Agency's notice by a more roundabout route. The three men were rescued against daunting odds by fate and by their families, and then all but forgotten. Yet they laid bare the pathological mistrust that fueled the arms race for the next 30 years.
Drawing on new interviews conducted in the United States, Europe and Russia with key players in the exchange and the events leading to it, among them Frederic Pryor himself and the man who shot down Gary Powers, "Bridge of Spies "captures a time when the fate of the world really did depend on coded messages on microdots and brave young men in pressure suits. The exchange that frigid day at two of the most sensitive points along the Iron Curtain represented the first step back from where the superpowers had stood since the building of the Berlin Wall the previous summer - on the brink of World War III.

Nuclear terrorism is such a disturbing prospect that we shy away from its details. Yet as a consequence, we fail to understand how best to defeat it. Michael Levi takes us inside nuclear terrorism and behind the decisions a terrorist leader would be faced with in pursuing a nuclear plot. Along the way, Levi identifies the many obstacles, large and small, that such a terrorist scheme might encounter, allowing him to discover a host of ways that any plan might be foiled.

Surveying the broad universe of plots and defenses, this accessible account shows how a wide-ranging defense that integrates the tools of weapon and materials security, law enforcement, intelligence, border controls, diplomacy, and the military can multiply, intensify, and compound the possibility that nuclear terrorists will fail. Levi draws from our long experience with terrorism and cautions us not to focus solely on the most harrowing yet most improbable threats. Nuclear terrorism shares much in common with other terrorist threats--and as a result, he argues, defeating it is impossible unless we put our entire counterterrorism and homeland security house in order.

As long as we live in a nuclear age, no defense can completely eliminate nuclear terrorism. But this book reminds us that the right strategy can minimize the risks and shows us how to do it.

NATO was hugely successful in facing off the Soviet Union during the Cold War. But has it been equally successful in addressing the "new threats" of the post-Cold War era? This new study assesses the organization's political and military initiatives, and how its outreach to Russia, Ukraine, and other countries in the Euro-Atlantic and Mediterranean regions, devoted considerable attention to WMD proliferation risks. It also probes the political factors, both inside and outside NATO, as well as resource constraints, which have limited the alliance's "added value" in the international community's effort to combat proliferation. The events of 11 September 2001 and bitter intra-alliance controversy over the 2003 Iraq intervention have highlighted questions regarding NATO's future role, and even its continued viability. This is a serious reflection on how the alliance should figure in the fight against WMD and terrorist threats and an examination of today's key issues, including the use of force in international relations and the possibility of constructing new, post-Cold War collective security rules. This is the first study to evaluate, critically and in-depth, how a long-standing security organization has adapted - and must continue to adapt - to the global security challenges of our time. This book will be of great interest to all students and scholars of international politics, military history and all readers interested in the future of NATO and international security.

No one better represents the plight and the conduct of German intellectuals under Hitler than Werner Heisenberg, whose task it was to build an atomic bomb for Nazi Germany. The controversy surrounding Heisenberg still rages, because of the nature of his work and the regime for which it was undertaken. What precisely did Heisenberg know about the physics of the atomic bomb? How deep was his loyalty to the German government during the Third Reich? Assuming that he had been able to build a bomb, would he have been willing? These questions, the moral and the scientific, are answered by Paul Lawrence Rose with greater accuracy and breadth of documentation than any other historian has yet achieved.
Digging deep into the archival record among formerly secret technical reports, Rose establishes that Heisenberg never overcame certain misconceptions about nuclear fission, and as a result the German leaders never pushed for atomic weapons. In fact, Heisenberg never had to face the moral problem of whether he "should" design a bomb for the Nazi regime. Only when he and his colleagues were interned in England and heard about Hiroshima did Heisenberg realize that his calculations were wrong. He began at once to construct an image of himself as a "pure" scientist who could have built a bomb but chose to work on reactor design instead. This was fiction, as Rose demonstrates: in reality, Heisenberg blindly supported and justified the cause of German victory. The question of why he did, and why he misrepresented himself afterwards, is answered through Rose's subtle analysis of German mentality and the scientists' problems of delusion and self-delusion. This fascinating study is a profound effort tounderstand one of the twentieth century's great enigmas.
