Why did Truman start his policy of containment?
Truman STARTED his policy of containment because George Keenan (our diplomat in Moscow) sent him a message outling the way that the U.S. would be able to contain communism in the Soviet Union. The policy of containment was based off this first outline and it was initiated because we believed that if not stopped communism would take over the world slowly but surely, look at our belief of the Domino Effect in communism.
