Under the Truman Doctrine, the United States agreed to:

B. push the Soviet Union out of Eastern Europe without the use of force.
C. engage in direct military action with the USSR to fight the spread of Communism.
D. create a buffer zone between Eastern Europe and the rest of Europe.

The Truman Doctrine was a pivotal Cold War policy announced by President Truman in 1947. It involved providing financial and military aid to countries threatened by Communist takeover, such as Greece and Turkey.

Truman's Doctrine aimed to contain the spread of Communism and prevent Soviet expansion beyond the 'iron curtain' in Eastern Europe. This policy set the stage for U.S. intervention in global conflicts to curb Communist influence.

The Truman Doctrine was part of a larger strategy of containment, which included initiatives like the Marshall Plan, NATO, and the Berlin Airlift. These efforts were crucial in shaping U.S. foreign policy during the early Cold War era.
