Truman Doctrine
During 1946, George Kennan, a top American diplomat stationed in Moscow, submitted an article to a magazine in which he gave a detailed analysis of America’s ideological struggle with its Communist rivals. Kennan’s piece gave way to the policy of containment, or method of isolating communism.
It was also during this period that another major policy came into play – the Truman Doctrine. In 1947, the British government announced they could no longer supply economic aid to Turkey and Greece.
However, both were in need of assistance and since the Soviets had wanted control of both Turkey and Greece, something had to be done. As a result, in March 1947 the Truman Doctrine was introduced. This doctrine pledged support both militarily and economically to those nations being threatened by communism.
