Reagan stopped communism by letting it collapse. In the United States, he had a military build up. He showed strength, not weakness. He was ready for any problem. He would face any threat. On the other hand, he was ready to deal with Gorbachev with respect. In other words he followed the advice of Teddy Roosevelt, "Speak softy and carry a big stick." He was ready to fight but had no desire to fight. He was an actor playing Teddy Roosevelt. The whole world recognized that attitude. Then, he expressed what Eastern Europe was feeling when he said, "Mr. Gorbachev, tear down this wall." He did not threaten but requested. The people of Eastern Europe arose as a group and threw off the Russian yolk. Russia had been able to deal with one country in the past. It could not deal with the entire Warsaw Pact at once. By speaking softly with TR's stick in reserve Reagan stopped communism. Reagan knew how to play the part of TR.
Alternatively, you could say that he was prepared to bring about nuclear Armageddon so the Soviets wisely backed down. However, this is very unlikely.
