Many countries were affected by communism after World War II. Since I can't see your map, I'll just give some examples.
Cuba- USSR supplied them with missiles to use as a defense mechanism (Cuban Missile Crisis), this was the closest the USA and the USSR came to fighting a war
Eastern European Countries- USSR took over and they became communist
The USA- Engaged in a Cold War with USSR from 1945 and until 1991
Vietnam- Vietnam War, Communists won and took control
Korea- The communists from the North tried to take over the non-communist South. They went to war and ended up splitting it in the middle (38th parallel).

Based on the tapes from the oval office, Richard Nixon felt that because he was president that he was above the law. This meant that the normal laws of the Untied States did not necessarily apply to him.
However, this was not the reality of the situation. In the Supreme Court case Nixon vs. United States, the Supreme Court ruled overwhelmingly that Nixon was not above the law and had to hand over the tapes to the court. This ultimately resulted in the resignation of Nixon.
