On this day in history, September 24th 1946, Clark Clifford and George Elsey, military advisers to US President Harry Truman, give the president a top-secret report on the Soviet Union that first recommends the containment policy. The United States' policy of containment entailed blocking as much as possible the expansion of Communism and the influence of the Soviet Union outside its post-WWII boundaries. The policy of containment marked a middle ground between détente (reconciliation) and rollback (aggressive attack), two Cold War strategies that were employed at other times during the conflict. The containment policy was first truly articulated and tested with the United States' actions in Greece and Turkey in 1947. Great Britain did not have the resources to continue supporting anti-Communist forces in the two nations, so the US agreed, as part of its containment policy, to shoulder the burden and give the necessary materials required by the anti-Communist forces in the two countries to fight the Communist advance. This set a precedent that saw the United States directly or indirectly aid anti-Communist forces in many countries throughout the world under the same pressure of Communism's expansion.
