The policy of containment allowed President Truman to send troops to fight in the Korean war.
Explanation:
The policy of containment is a foreign policy during the Cold War of the United States to limit the spread of communism after World War II. It provided support for countries that rejected communism. Americans fought on the sides of the nationalists to try to stop the spread of communists, especially in Asia. President Truman decided to send troops in Korea through Japan to stop communism entering South Korea. Americans believed that if it not stopped then it might encourage China to invade Taiwan and Japan (domino effect).
