wtf is bad about anti-Soviet foreign policy

The Soviets wanted deescalation after WW2, and supported self determination for liberated countries including Korea, Vietnam, Greece and Italy. Whatever you think of communism, the American policy of "containment" is directly and indisputably responsible for the suppression of democracy in dozens of countries and wars which killed tens of millions of people all because some of those people would have elected communist and socialist leaders we didn't like.
