So is every leftist government that the US overthrew a totalitarian Soviet puppet state? Lets use the Guatemala example for one...
In the early 50s, the president of Guatemala, who was democratically elected, was making socialist land reforms that would
redistribute unused land to local peasants for agriculture. Some of that land had been set aside by previous, somewhat corrupt governments for the use of the United Fruit Company (based in the US obviously). United Fruit, which was huge at the time, was unsatisfied with the compensation from the Guatemalan government for the expropriation of the land, and lobbied the US government for action. The CIA then hatched a plan that involved supporting an exiled Guatemalan army officer in a military takeover, as well as several assassinations of government officials. By the way, Allen Dulles, the CIA director at the time, was a large shareholder of the United Fruit Company... The coup was successful and the elected government was replaced by a military junta. After this, the CIA launched
Operation PBHISTORY which was supposed to find links between the Guatemalan communists and the Soviet Union. They found none.
So the end result was that the US replaced a freely elected and benevolent socialist government with a military dictatorship. The Soviets had nothing to do with Guatemala, the Americans turned it into a puppet state in the name of bananas. This is what your country did during the Cold War. It was not out to look for the world's freedom or thwart totalitarianism, it was looking after its own interests and it fucked up a lot of good people while doing so. The US backed up a lot of horrible, totalitarian dictators during the Cold War; Suharto in Indonesia, Marcos in the Philippines, Pinochet in Chile, and many others.
