The New York Times begins publication of the Pentagon Papers, a top-secret U.S. Department of Defense history of the country’s political-military involvement in Vietnam from 1945 to 1967. The papers reveal that the U.S. had deliberately expanded its war with carpet bombing of Cambodia and Laos, coastal raids on North Vietnam, and Marine Corps attacks, and that four presidential administrations, from Truman to Johnson, had deliberately misled the public regarding their intentions toward Vietnam.
