The Truman Doctrine of 1947 was announced to achieve which one of the following?

The Truman Doctrine, announced by President Harry S. Truman on March 12, 1947, was a pivotal shift in American foreign policy aimed at the containment of the USSR and the spread of communism [2]. It established that the United States would provide political, military, and economic assistance to democratic nations facing threats from external or internal authoritarian forces [3]. The doctrine was specifically triggered by the withdrawal of British support from Greece and Turkey, where communist insurgencies and Soviet territorial demands posed significant risks [2]. By committing $400 million in aid to these nations, Truman sought to bolster pro-Western governments and prevent the expansion of Soviet totalitarianism into independent states [4]. This policy of containment became the foundational principle of U.S. foreign policy throughout the Cold War era.
