After WWII concluded, peace did not last very long. Tension began to grow between the two superpowers as the Soviet Union began to establish communist governments in eastern European countries. The Soviets began to spread their communist beliefs around the world. The United States reacted to this situation by implementing the “Containment Policy” to prevent the spread of Communism.
I believe if the Containment policy was not put into affect, the world would be a very different place. The United States might not have interviened in Vietnam and communism may had spread throughout south east Asia. If there was no Containment policy, the United States may not have assisted South Korea during the Korean war and the entire peninsula may have been taken over by the Communist party.
