Marc Ambinder explains the anxious period between the United States and the Soviet Union from 1982 to 1984, with the “Able Archer ’83” war game at the center of the tension. With astonishing and clarifying new details, he recounts the scary series of the close encounters that tested the limits of ordinary humans and powerful leaders alike. Ambinder provides a comprehensive and chilling account of the nuclear command and control process, from intelligence warnings to the composition of the nuclear codes themselves. And he affords glimpses into the secret world of a preemptive electronic attack that scared the Soviet Union into action. Ambinder’s account reads like a thriller, recounting the spy-versus-spy games that kept both countries—and the world—in check.
