It's a good thing that you have understood the effects of communism. Communists are the worst. Now understand the other side, which you are part of. The then president of the USSR in 1971 got so mad at the blatant support of the US to the genocide of millions that he was angry at US for years. That's US for you. If US is hated for it's support of it's atrocities by the worst commies, what category should i keep the US in??
A few questions to think for you. How many countries does US intervene in ? How many years of it's history is free from war? How many people died as a result of it's actions?
Just a small insight: History of U.S. Military Interventions since 1890
