1. What are nuclear weapons?

How did nuclear weapons differ from what came before? ‘What are nuclear weapons?’ explains the science behind their creation by looking at the characteristics of the atom and the harnessing of its power for destructive purposes. The peaceful end of the Cold War was not the end of the nuclear threat. The detonation of a relatively small nuclear weapon in New York would be catastrophic, with the medical system unable to respond to the task of caring for the injured. After 9/11 and with an increased threat from rogue states, are we on the brink of a second nuclear age?

Atomic energy is the source of power for both nuclear reactors and nuclear weapons. This energy comes from the fission or fusion of atoms. ‘What are nuclear weapons?’ explains how a nuclear weapon works by looking at the characteristics of an atom and charts the discovery of the power of the atom for destructive purposes. The peaceful end of the Cold War did not mean the end of nuclear threats. We don't like to imagine the scenario of the use of nuclear weapons today. The task of caring for the injured would literally be beyond the ability of any medical system to respond.

The decline in international tension following the end of the communist regimes of the Soviet bloc produced a massive shift in the ideology of the nuclear in the 1990s. The de-targeting and dismantling of large numbers of nuclear weapons and the demise of the threat of nuclear annihilation created new conditions both for international security and for the writing of nuclear history. With the declassification and release of large quantities of official documentation from the former adversaries, as well as the fiftieth anniversary of the bombings of Hiroshima and Nagasaki in 1995, a burst of histories of various aspects of the nuclear age have appeared over the last ten years, exploring not just the technopolitics, strategy and operational logistics of the Cold War and the arms race, but the cultural history of the nuclear age, its imagery, its architecture, its oppositional politics and its effects on the landscape, national and regional economies and cultures and indeed everyday life. At a time of global economic and political uncertainty and the emergent threat of capricious international terrorism and new nuclear proliferation, the apparent certainties of the Cold War now even evoke a certain nostalgia, and its artefacts and structures are being recast as ‘heritage’.

This chapter examines the role played by nuclear weapons in international politics during and after the cold war, making a distinction between the First Nuclear Age and the ongoing Second Nuclear Age. After providing a background on the First Nuclear Age, the chapter considers the various risks present in the Second Nuclear Age, focusing on issues related to nuclear deterrence, nuclear proliferation networks, strategic culture, and ballistic missile defences. It then discusses the assumption that arms control and disarmament treaties are the best means to further counterproliferation efforts. It also assesses the future of nuclear weapons and whether the world is facing a Third Nuclear Age before concluding with an analysis of the relevance of deterrence in the face of changing political and technological circumstances.

Abstract In the Anthropocene, International Relations must confront the possibility of anthropogenic extinction. Recent, insightful attempts to advance new vocabularies of planet politics tend to demote the profound historical and intellectual links between our current predicament and the nuclear age. In contrast, we argue that it is vital to revisit the nuclear-environment nexus of the Cold War to trace genealogies of today's intricate constellation of security problems. We do so by reappraising the work of Jonathan Schell (1943–2014), author of The Fate of the Earth (1982), who came to regard extinction as a defining feature of the nuclear age. We show how a deep engagement with nuclear weapons led Schell to an understanding of the Earth as a complex, delicate ecology and fed into a sophisticated, Arendtian theory of extinction. Despite its limitations and tensions, we argue that Schell's work remains deeply relevant for rethinking human–Earth relations and confronting the Anthropocene.

This chapter examines how nuclear weapons have influenced international politics, both during and after the cold war. In particular, it distinguishes between the spread of nuclear weapons to more states, which poses an increasing threat to international security, and the decline in the absolute number of nuclear weapons due to the reductions in U.S. and Russian nuclear arsenals. The chapter first provides an overview of the First Nuclear Age — which lasted approximately from 1945 to the 1991 fall of the Soviet Union — before discussing the risks in the Second Nuclear Age. It also considers other contemporary issues such as ballistic missile defences, the cultural dimensions of nuclear weapons acquisition, and the possibility of using nuclear weapons for terrorism. The chapter concludes by reflecting on the prospects for a Third Nuclear Age.

Plutonium symbolizes everything we associate with the nuclear age. It evokes the entire gamut of emotions from good to evil, from hope to despair, and from the salvation of humanity to its utter destruction. No other element bears such a burden. Its discovery in 1941, following the discovery of fission in 1938, unlocked the potential and fear of the nuclear age. During the Cold War, the primary interest in plutonium was to provide triggers for thermonuclear weapons that formed the basis of nuclear deterrence. Beginning in the 1950s, plutonium also became an integral part of the quest for nearly limitless electrical power. The end of the Cold War has dramatically altered the military postures of the United States and Russia, allowing each to reverse the engines fueling the nuclearweapons buildup. Now, both countries face the challenge of keeping the remaining stockpile of nuclear weapons safe and reliable without nuclear testing, as well as cleaning up nuclear contamination and preventing the spread of nuclear weapons and terrorism. Moreover, current concerns about energy availability and global warming have rekindled interest in nuclear power.

Leading analysts have predicted for decades that nuclear weapons would help pacify international politics. The core notion is that countries protected by these fearsome weapons can stop competing so intensely with their adversaries: they can end their arms races, scale back their alliances, and stop jockeying for strategic territory. But rarely have theory and practice been so opposed. Why do international relations in the nuclear age remain so competitive? Indeed, why are today's major geopolitical rivalries intensifying? This book tackles the central puzzle of the nuclear age: the persistence of intense geopolitical competition in the shadow of nuclear weapons. The book explains why the Cold War superpowers raced so feverishly against each other; why the creation of “mutual assured destruction” does not ensure peace; and why the rapid technological changes of the 21st century will weaken deterrence in critical hotspots around the world. By explaining how the nuclear revolution falls short, the book discovers answers to the most pressing questions about deterrence in the coming decades: how much capability is required for a reliable nuclear deterrent, how conventional conflicts may become nuclear wars, and how great care is required now to prevent new technology from ushering in an age of nuclear instability.
