I need help for this three questions:

Answer 1

1. During the Cold War era, the policy of containment was the principle that communist governments will eventually fall apart as long as they are prevented from expanding their influence.

2. Korean War, Vietnam War, Marshall Plan

3. West Berlin was in the Soviet-controlled zone within East Germany. It was literally in the mercy of the enemy, and that posed a dire problem, which can be seen when the Soviet Union blockaded West Berlin.
