In a speech to the United Nations General Assembly in September 1961, President John F. Kennedy told his audience that "every man, woman, and child lives under a nuclear sword of Damocles, hanging by the slenderest of threads." In this sweeping, immersive, and now chillingly relevant history of nuclear confrontation, eminent historian and diplomat Rodric Braithwaite offers the tale of that slender thread, a tale that spans from the dropping of the atomic bomb on Hiroshima and Nagasaki in August 1945 into the present. Here is an account of treaties and summits, of life-and-death strategy among nations, featuring a vast and varied cast of individuals--scientists, spies, diplomats, generals, politicians, shamans, writers, geniuses, the hight-minded and the crackpot--all ow whom played their part in shaping the Nuclear Age. As [this book] shows, containing atomic weapons has been a central preoccupation of global politics and policy for the last seven decades. In the years after World War II, atomic weapons were initially controlled only by the superpowers, first the United States, followed shortly by the former Soviet Union (mainly by having infiltrated the Manhattan Project), then developed in succession by England, France, China, India, and Pakistan. In recent years, North Korea has developed a nuclear weapons program and is now developing the means of delivering them. Nuclear proliferation has long dominated and even obsessed international diplomacy and policy, particularly as the capacity to unleash catastrophic destruction became widespread. Braithwaite offers an overview of policy from the Cold war reliance on what was termed "Deterrence," a policy of Mutually Assured Destruction (MAD), to the "Armageddon theology" of Ronald Reagan, to the de-alerting of nuclear weapons promised by both George W. Bush and Barack Obama, to the fire and fury driving the current war of tweeted insults. For nearly three-quarters of a century, nuclear weapons have shadowed human existence, moving from crisis to quiescence and back to crisis. Armageddon and Paranoia comes at a time when tensions are mounting once more. Though we cannot un-invent the atomic bomb, Braithwaite's clear-sighted and illuminating history provides a deeper understanding of how it has shaped the world in which we live. -- Dust jacket.
