The Truman Doctrine

On Dec. 31, 1946, President Truman declared an end to the period of World War II hostilities. Early in 1947 the British said they could not support the Greek government after March 31. Many diplomats feared that the Soviet Union would then spread its power throughout the Middle East. President Truman met the problem by asking Congress for 400 million dollars to aid Greece and Turkey. Congress appropriated the money. This policy of aid, popularly known as the Truman Doctrine, was an American challenge to Soviet ambitions throughout the world.
