How far does Truman's speech to Congress (1947) support the interpretation that the USA.. (see details) thanks?

Truman used the warning by American diplomat george F. Keenan as the basis for the Truman Doctrine. Keenan warned that the USSR was "a political force committed fanatically to the belief that with the U.S. there can be no permanent 'modus vivendi,'" and that the only answer was "a long-term, patient but but firm and vigilant containment of Russian expansive tendencies." In Truman's address he stated "I believe that it must be the policy of the United States to support free peoples who are resisting attempted subjugation by armed minorities or by outside pressures." In the same speech he requested $400 million--part of it to bolster the armed forces of Greece and Turkey, another part to provide economic istance to Greece. This was directly in the face of the Soviet Union.
