The USA did no such thing. The USSR was all over the world, spreading its goal of world communism. That was the only reason the Soviet Union existed. The USA had nothing to do with the Soviet Union quitting Afghanistan. It was the collapse of the Soviet Union itself that caused them to quit. Soviet soldiers fighting in Afghanistan had not been paid in years. There was simply no more money. The last time I checked, you Americans are running into similar difficulties, borrowing like mad to pay for your Afghanistan/Iraq adventures which have set your country into horrid debt. The USSR spent far, far more than the USA for their own adventures spreading communism around the world. You don't think those anti-nuke activists from the past came out of nowhere and acted on their own beliefs, do you? Never read about the declassified KGB archives which showed such groups were actually the creation of the KGB??
