From the Pulitzer Prize–winning author of The Making of the Atomic Bomb: the story of the entire postwar superpower arms race, climaxing during the Reagan-Gorbachev decade when the United States and the Soviet Union came within scant hours of nuclear war—and then nearly agreed to abolish nuclear weapons.In a narrative that reads like a thriller, Rhodes reveals how the Reagan administration’s unprecedented arms buildup in the early 1980s led ailing Soviet leader Yuri Andropov to conclude that Reagan must be preparing for a nuclear war. In the fall of 1983, when NATO staged a larger than usual series of field exercises that included, uniquely, a practice run-up to a nuclear attack, the Soviet military came very close to launching a defensive first strike on Europe and North America.
