Answer :
The policy introduced in President Truman's speech affected tensions between the United States and the Soviet Union by deepening tensions. It did so by formalizing the United States' policy of stopping the Soviet Union from extending its sphere of influence. This policy, known as the Truman Doctrine, marked a shift in U.S. foreign policy towards containment of Soviet expansionism.
1. The Truman Doctrine aimed to provide economic and military aid to countries threatened by communism, which was seen as a direct challenge to the Soviet Union's influence.
2. By offering support to countries like Greece and Turkey to resist communism, the U.S. signaled its commitment to opposing Soviet efforts to spread their ideology and control.
3. This formalized stance against Soviet expansionism heightened tensions between the U.S. and the Soviet Union, setting the stage for the Cold War confrontation that followed.
In summary, President Truman's policy announcement in his speech deepened tensions between the United States and the Soviet Union by formalizing the U.S. commitment to containing Soviet influence, leading to increased rivalry and conflict during the Cold War era.
