The U.S. barges in on too many affairs, the Cuban embargo is just there because we don't like the way Cuba is run, honestly the U.S. should not have its nose in other global affairs. We also had the Korean war just because we didn't want Korea to be run by communists .
Why do you say countries like Russia? The cold war has long ended, we not have opinions of other countries. Many stressed relations would never have happened if not for the U.S, "barging in", let 's think back a few years President Bush is elected afterwords we go to war with Afghanistan all because they were run by the Taliban to oust them from power. Simply the U.S. did not like the way Afghanistan was run.
