The Truman administration increased American involvement in Vietnam primarily through its support for the French colonial efforts to regain control after World War II. In 1950, the U.S. began providing military and financial aid to France, viewing the conflict as part of the broader struggle against communism during the Cold War. Truman's commitment to the policy of containment laid the groundwork for deeper U.S. engagement in Vietnam, signaling a shift in American foreign policy towards direct involvement in Southeast Asia. This set the stage for subsequent administrations to escalate U.S. military presence and involvement in the region.
