One of Truman's most important policies was the Truman Doctrine.
The Truman Doctrine was a foreign policy of president Harry Truman in which he tried to stop the power/influence of the Soviet Union. After World War II, Truman was worried that if nations located near the Soviet Union did not receive financial help, they would fall into the hands of the communist system. At this time, Truman wanted to make sure that he stopped the spread of communism in any way possible.
To do this, Truman asked Congress to provide $400 million to countries like Greece and Turkey. These were two main targets of US help, as they were located close to the Soviet Union. Ultimately, this money would help to stabilize their economy and fend off communism.
