What was the Truman Doctrine?
On March 12, 1947, United States President Harry S. Truman announced the Truman Doctrine. Post World-War II, the British government was unable to provide economic and military aid to Greece and Turkey, both of which faced internal and external communist pressures such as overthrowing the royal Greek government, Greece's economy being nearly destroyed, the Soviet Union demanding joint control of the Turkish Dardanelles and Bosporous straits, as well as Moscow demanding open naval access from the Black Sea to the Mediterranean (https://www.historyextra.com/period/cold-war/what-was-truman-doctrine-speech-communism/).
Furthermore, President Truman argued that the United States must support "free peoples who are resisting attempted subjugation by armed minorities or by outside pressures." This statement signaled a new role America gained in global affairs. For example, America stopped waiting for overseas crises to reach its shores, and the United States pledged military and economic aid anywhere freedom faced a threat (https://history.state.gov/milestones/1945-1952/truman-doctrine).
For instance, Greece received military and economic support during its Civil War to defeat the communist insurgency. To the East, Turkey was given aid to resist Soviet influence, regarding the straits connecting the Black Sea and the Mediterranean. Moreover, both countries’ assistance led to their stability and communist-free societies, leading to them joining NATO in 1952 (https://www.youtube.com/watch?v=iEkvGFV0_kE&t=8s).
Overall, the Truman Doctrine is viewed as a policy to contain worldwide Soviet influence. The signing gave American foreign policy the upper hand to become involved in giving aid and being involved in international affairs.
