Briefly explain one advantage or benefit to America of the nation's pursuit of the foreign policy depicted in the cartoon. Obviously, the cartoon depicts the Truman Doctrine:
In 1947, President Harry S. Truman pledged that the United States would help any nation resist communism in order to prevent its spread. His policy of containment is known as the Truman Doctrine.

Does anyone know what benefits/advantages America sowed from this Doctrine? Thanks!
