Every nuclear weapons program for decades has relied extensively on illicit imports of nuclear-related technologies. This book offers the most detailed public account of how states procure what they need to build nuclear weapons, what is currently being done to stop them, and how global efforts to prevent such trade could be strengthened. While illicit nuclear trade can never be stopped completely, effective steps to block illicit purchases of nuclear technology have sometimes succeeded in slowing nuclear weapons programs and increasing their costs, giving diplomacy more chance to work. Hence, this book argues, preventing illicit transfers wherever possible is a key element of an effective global non-proliferation strategy.

During the Cold War, the United States conducted atmospheric tests of nuclear weapons in the Marshall Islands of the Pacific. The total explosive yield of these tests was 108 megatons, equivalent to the detonation of one Hiroshima bomb per day over nineteen years. These tests, particularly Castle Bravo, the largest one, had tragic consequences, including the irradiation of innocent people and the permanent displacement of many native Marshallese. Keith M. Parsons and Robert Zaballa tell the story of the development and testing of thermonuclear weapons and the effects of these tests on their victims and on the popular and intellectual culture. These events are also situated in their Cold War context and explained in terms of the prevailing hopes, fears, and beliefs of that age. In particular, the narrative highlights the obsessions and priorities of top American officials, such as Lewis L. Strauss, Chairman of the Atomic Energy Commission.

A new approach to nuclear disarmament, nonproliferation, and the prevention of nuclear terrorism that focuses on controlling the production and stockpiling of nuclear materials. Achieving nuclear disarmament, stopping nuclear proliferation, and preventing nuclear terrorism are among the most critical challenges facing the world today. Unmaking the Bomb proposes a new approach to reaching these long-held goals. Rather than considering them as separate issues, the authors-physicists and experts on nuclear security-argue that all three of these goals can be understood and realized together if we focus on the production, stockpiling, and disposal of plutonium and highly enriched uranium-the fissile materials that are the key ingredients used to make nuclear weapons. The authors describe the history, production, national stockpiles, and current military and civilian uses of plutonium and highly enriched uranium, and propose policies aimed at reducing and eventually eliminating these fissile materials worldwide. These include an end to the production of highly enriched uranium and plutonium for weapons, an end to their use as reactor fuels, and the verified elimination of all national stockpiles.

Nuclear Reactions explores the nuclear consensus that emerged in post-World War II America, characterized by widespread support for a diplomatic and military strategy based on nuclear weapons and a vision of economic growth that welcomed nuclear energy both for the generation of electricity and for other peaceful and industrial uses. Unease about the environmental consequences of nuclear energy and weapons development became apparent by the early 1960s and led to the first challenges to that consensus. The documents in this collection address issues such as the arms race, "mutually assured destruction," the emergence of ecosystems ecology and the environmental movement, nuclear protests, and climate change. They raise questions about how nuclear energy shaped-and continues to shape-the contours of postwar American life. These questions provide a useful lens through which to understand the social, economic, and environmental tradeoffs embedded within American choices about the use and management of nuclear energy.

The Nuclear Nonproliferation Treaty (NPT) has been the principal legal barrier to prevent the spread of nuclear weapons for the past forty-five years. It promotes the peaceful uses of nuclear technology and insures, through the application of safeguards inspections conducted by the International Atomic Energy Agency (IAEA), that those technologies are not being diverted toward the production of nuclear weapons. It is also the only multinational treaty that obligates the five nuclear weapons states that are party to the treaty (China, France, Great Britain, Russia, and the United States) to pursue nuclear disarmament measures.Though there have been many challenges over the years, most would agree that the treaty has largely been successful. However, many are concerned about the continued viability of the NPT. The perceived slow pace of nuclear disarmament, the interest by some countries to consider a weapons program while party to the treaty, and the funding and staffing issues at the IAEA, are all putting considerable strain on the treaty. This manuscript explores those issues and offers some possible solutions to ensure that the NPT will survive effectively for many years to come.

Four decades have passed since India conducted its first nuclear test. Since then the world has undergone a transition, both in terms of power dynamics and military warfare. The emergence of New Nuclear and Threshold states has transformed the traditional military warfare, making it more asymmetric. Though the concept of nuclear deterrence in the American strategic thought has diminished, but the Asian countries still consider nuclear weapons as an important strategy in combating conventional weaknesses. This altered strategic space has created problems in the civilian and the military domains. The emergence of economically strong China aiming for military modernization, to achieve global reach through precision missiles, is making Asia edgy. A nuclear Pakistan which is constantly increasing its nuclear stockpile is creating stability-instability paradoxes in Asia. India which is also emerging as a powerful state needs to approach this dynamic shift in a holistic manner. A strategic churning has begun in Asia and whether this will be in India's favour depends on the strategic choices that India adopts.China has revolutionized its Second Artillery through a process of "Informationalisation and Modernisation" and is diversifying the military technology which is having a cascading effect in Asia. Pakistan through its nuclear policy of "First Use", its alleged use of "Tactical Nuclear Weapons" is making South Asia vulnerable to nuclear terrorism. Under such conditions are there any gaps between India's nuclear doctrine and its force structure? Can India's nuclear strategy counter China? Is India capable of countering a Sino-Pak nexus? These are a few questions along with others which this book will try to unravel.
