full_context: Document 1: Truman Committee: The Truman Committee, formally known as the Senate Special Committee to Investigate the National Defense Program, was a United States Congressional investigative body headed by Senator Harry S. Truman. The bipartisan special committee was formed in March 1941 to find and correct problems in US war production—problems with waste, inefficiency and war profiteering. The Truman Committee proved to be one of the most successful investigative efforts ever mounted by the US government: an initial budget of $15,000 was expanded over three years to $360,000 to save an estimated $10–15 billion in military spending, and thousands of lives of US servicemen. For comparison, the entire cost of the Manhattan Project was $2 billion, at the time. Chairing the committee helped Truman make a name for himself beyond his political machine origins, and was a major factor in the decision to nominate him as vice president, which would propel him to the presidency following the death of Franklin D. Roosevelt.
Document 2: Harry S. Truman: Harry S. Truman (May 8, 1884December 26, 1972) was the 33rd President of the United States (1945–53), assuming that office upon the death of Franklin D. Roosevelt during the waning months of World War II. He is known for launching the Marshall Plan to rebuild the economy of Western Europe, for leading the Cold War against Soviet and Chinese communism by establishing the Truman Doctrine and NATO, and for intervening in the Korean War. In domestic affairs, he was a moderate Democrat whose liberal proposals were a continuation of Franklin Roosevelt's New Deal, but the conservative-dominated Congress blocked most of them. He used the veto power 180 times, more than any president since then, and saw 12 overridden by Congress; only Grover Cleveland and Franklin D. Roosevelt used the veto so often, and only Gerald Ford and Andrew Johnson saw so many veto overrides. He is also the only world leader to have ever used nuclear weapons in war, desegregated the U.S. Armed Forces, supported a newly independent Israel, and was a founder of the United Nations.

The Act was reauthorized in 1950 , but in 1951, it and the Economic Cooperation Act were succeeded by the Mutual Security Act, and its newly created independent agency, the Mutual Security Administration, to supervise all foreign aid programs, including both military assistance programs and non-military, economic assistance programs that bolstered the defense capability of U.S. allies.

May, NSC-68 "provided the blueprint for the militarization of the Cold War from 1950 to the collapse of the Soviet Union at the beginning of the 1990s." NSC-68 and its subsequent amplifications advocated a large expansion in the military budget of the United States, the development of a hydrogen bomb, and increased military aid to allies of the United States.
