mar 12, 1947 - Truman Doctrine
The Truman Doctrine was a de facto declaration of the Cold War. Truman’s address outlined the broad parameters of U.S. Cold War foreign policy: the Soviet Union was the center of all communist activity and movements throughout the world; communism could attack through outside invasion or internal subversion; and the United States needed to provide military and economic assistance to protect nations from communist aggression.
