The Truman Doctrine speech was written in response to the Soviet Union's expansionist policies in Europe and the Mediterranean. President Harry Truman delivered the speech to Congress on March 12, 1947, in which he asked for $400 million in aid to help Greece and Turkey resist communism. The speech established the policy of containment, which aimed to prevent the spread of Soviet influence beyond its current borders. The Truman Doctrine reflected the US's determination to counter Soviet expansionism and safeguard the stability of the free world.
