"In 1991, dissident officials in the Soviet Union launch a nuclear missile at Donetsk from a site in NATO member Turkey. The Soviet automated defence systems, believing that a NATO attack is in progress, execute a measured launch of intercontinental ballistic missiles (ICBMs) at the United States. After Donetsk is destroyed, the Strategic Air Command (SAC) scrambles its forces and SAC Commander General Renning urges the US president to authorize a full counterattack. The Soviet leader explains the dissidents' actions to the US president. He asks the US to stand down, but he is willing to accept a US counterstrike comparable to the Soviets' strike, costing each side six to nine million people. If the United States launches an all-out attack, the Soviets will respond in kind and doom the whole planet." https://en.wikipedia.org/wiki/By_Dawn's_Early_Light#Plot
