Answer :
The purpose of the Truman Doctrine was to contain the spread of communism and strengthen non-communist countries bordering the Soviet Union. This policy was announced by President Harry S. Truman in 1947 and aimed to provide economic and military assistance to countries facing threats from communist expansion, particularly in Europe.
By offering support to these nations, the United States aimed to prevent the further spread of communism and to bolster the defense of democratic countries in the face of Soviet influence. The Truman Doctrine was a key component of the U.S. foreign policy during the early years of the Cold War, emphasizing the containment of communism as a central goal.
Overall, the Truman Doctrine was instrumental in shaping U.S. foreign policy and defining the approach to dealing with the challenges posed by the Soviet Union and communism in the aftermath of World War II.
