What were some of the effects of the western powers' fears of communist expansion?

The Western Powers' fear of communist expansion resulted in several different effects including:

1) Marshall Plan- This US law implemented right after World War II, gave $13 billion worth of aid to countries that suffered financially after this war. The US feared that failing to help these countries (like Great Britain, Turkey, France, etc.) would result in these nations falling under the control of the Soviet Union and the communist system.

2) North Atlantic Treaty Organization (NATO)- This military and political alliance was created so that nations had numerous allies in case of another war starting. This ensured that Western nations would help protect each other in the instance of an attempted communist takeover. Countries that were part of NATO include the United States, Great Britain, France, and Denmark.
