Truman commits America to fighting communism everywhere
What happened
When Britain announced it could no longer afford to fund the Greek government's war against Communist insurgents, President Truman asked Congress for 400 million dollars to aid both Greece and Turkey, framing the request in sweeping terms: 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. Truman argued a Communist Greece would destabilize Turkey and then the entire Middle East. Ironically, Soviet leader Joseph Stalin had actually refrained from arming the Greek Communists at all, even pressuring Yugoslavia to stop, a fact American officials at the time did not know.
Why it matters
The Truman Doctrine reversed a longstanding American tradition of avoiding commitments outside the Western Hemisphere in peacetime, committing the United States instead to a strategy of containment that would justify American intervention on every continent for the next four decades.
How we know
Truman's speech to the joint session of Congress was recorded verbatim in the Congressional Record, and later Soviet archival releases confirmed Stalin's actual noninvolvement in the Greek Civil War, a detail unknown to Truman's own administration when it made its case.
