Document 3: NSC-68: National Security Council Report 68 (NSC-68) was a 58-page top secret policy paper by the United States National Security Council presented to President Harry S. Truman on April 14, 1950. It was one of the most important statements of American policy that launched the Cold War. In the words of scholar Ernest R. 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. It made the containment of global Communist expansion a high priority. NSC-68 rejected the alternative policies of friendly détente and rollback against the Soviet Union.

Roosevelt used the veto so often, and only Gerald Ford and Andrew Johnson saw so many veto overrides.

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.
