The National War College is located inside the National Defense University, which is located just across the river from the Pentagon. Each day, to play the [1983 Proud Prophet war] game, the secretary of defense would pick up a red phone and call the chairman of the Joint Chiefs of Staff to discuss various ideas in the different nuclear war scenarios put forth by [Thomas] Schelling. Schemes included everything from tactical nuclear strikes in a so-called limited nuclear war, to massive decapitation-event scenarios. There were exercises with NATO and without NATO nuclear forces getting involved. There were scenarios where the U.S. launched nuclear war preemptively, beginning with everyone at the Pentagon in a state of focused calm. There were exercises where nuclear war war launched in crisis mode. In full-on panic mode. With and without China entering the conflict. With and without the UK involved.
Paul Bracken, a professor of political science at Yale, was one of the civilian individuals invited to participate in playing the classified nuclear war game. The results were horrifying, Bracken says. Over the course of two weeks, in every simulated scenario—and despite whatever particularly triggering event started the war game—nuclear war always ended the same way. With the same outcome. There is no way to win a nuclear war once it starts. There is no such thing as de-escalation.
According to Proud Prophet, regardless of how nuclear war begins, it ends with complete Armageddon-like destruction. With the U.S., Russia, and Europe totally destroyed. With the entire Northern Hemisphere uninhabitable from fallout. With the death of, at minimum, a half billion people in the war’s opening salvo alone. Followed by the starvation and death of almost everyone who initially survived.
