The Pentagon Papers, leaked by Daniel Ellsberg in 1971, revealed:

Question

Accepted Answer

That the government had systematically misled the public about the war. The Pentagon Papers were a classified Department of Defense study that revealed the government had systematically misled the American public about the extent of U.S. involvement in Vietnam and the prospects for success. The documents showed that administrations from Truman through Johnson had expanded the war while publicly expressing optimism.

While secret negotiations did occur, they were not the primary revelation of the Pentagon Papers; the documents focused on decision-making history rather than ongoing diplomatic contacts. No plans for nuclear strikes against Hanoi were contained in the papers - while nuclear options were occasionally discussed at the highest levels, they were not part of the Pentagon Papers revelations. Evidence that South Vietnam was winning directly contradicts what the papers showed, which was a pattern of private pessimism alongside public optimism.

The Pentagon Papers are essential DSST exam material because they dramatically deepened the credibility gap between the government and the American people. The Nixon administration's attempt to suppress publication through prior restraint led to the landmark Supreme Court case New York Times Co. v. United States, which reinforced freedom of the press. Ellsberg's prosecution also led to the formation of the "Plumbers" unit, connecting the war to the Watergate scandal.
