Final answer:
The United States reviewed its policies in containing communism during the Cold War due to the fear of its spread and the threat it posed. Steps taken included economic aid, military alliances, and internal efforts to root out Communist influences.
Step-by-step explanation:
During the Cold War, the United States reviewed and adapted its policies in containing communism due to various reasons. One main reason was the fear of the spread of communism and the threat it posed to American capitalism and democracy. The United States government believed that an aggressive approach was necessary to prevent the expansion of communism and protect its own interests.
Some of the steps taken by the U.S. government to oppose Communist expansion in Europe and Asia included the implementation of the Marshall Plan, which provided economic aid to Western European countries to rebuild their economies and prevent them from turning communist. The U.S. also formed military alliances like NATO to deter Soviet aggression. In addition, the U.S. engaged in proxy wars, such as the Korean War and the Vietnam War, to prevent the spread of communism.
Internally, the U.S. government also made efforts to root out Communist influences through policies like McCarthyism, which targeted individuals suspected of being communists or sympathizers. This included investigations, interrogations, and blacklisting of suspected communists in various industries.
