What was the significance of Truman Doctrine?

The Truman Doctrine was first announced to Congress by President Harry S. Truman on March 12, 1947. It was a foreign policy carried out by the US during the Cold War. It implied US support for other nations thought to be threatened by Soviet geopolitical expansion.

The Truman Doctrine was in fact a de facto declaration of the Cold War. It was designed to provide political, military and economic assistance to foreign countries to contain Communism from spreading any further and establish U.S. military bases around the world.

It was further developed on July 4, 1948, when the American Congress decided to support Greece and Turkey who were then experiencing internal uprising led by communist forces.

The Truman Doctrine demonstrated that the United States was not willing to return to isolationism after World War two, but rather take an active role in world politics.

Harry Truman, who was president at the end of World War II and the start of the Cold War, is most closely associated with Containment.
