With all things considered abroad, was it (in your opinion) a good thing that Truman, Ike, Kennedy, Johnson, Nixon, Reagan and their respective administrations tried to prevent communism from spreading? I'm not speaking in terms of specifically how the prevention was executed, but in terms of "Was the move to prevent it from spreading in the best interests of the United States and World peace?"
What would have happened if we had not made a stand in Berlin(Berlin Airlift)? How about Korea in 1950? How would the world be today had we just let some of these nations that had Soviet Union support go at it without intervention?
Was it good, or a total waste of taxpayers dollars?
