On December 27, 1979, Soviet troops invaded Afghanistan. On December 28, the US issued an ultimatum that the Russians withdraw immediately. That same day, the first missiles cleared their silos.
For most Americans, the war lasted for about eight hours.
Washington D.C. was obliterated.
The far western states are lifeless wastelands.
The major ports were destroyed.
The government ceased to exist.
We won. The Russians had it worse.
That’s about all anyone still alive knows.
