Has anyone read Marc Ambinder's The Brink: President Reagan and the Nuclear War Scare of 1983?
It's the companion, more or less, to the one from earlier this year that Taylor Downing wrote, and gives further insight into that year and some of the thereafter parts. One of the major twists: As the U.S. ran its annual non-NATO nuclear war game, called Night Hawk '84, in April 1984, the Soviets suddenly ramped all the way up on alert, steaming a 200 ship armada out of the Kola Pennisula, sending Backfires out over Norway, sending other strategic bombers to East Germany, putting interceptors on runway alert...it scared the crap out of us. The Pentagon played it cool, but behind the scenes there was near panic that war would start by sheer accident. Even worse, the Soviets had semi-cracked our nuclear communications codes. If we escalated, they'd have more advance knowledge than the norm.
What really gets me is that about 7-8 years after Macragge begat us this darkly beautiful alter-verse, his war date was less than two months off of what nearly was war.
