THE PENTAGON PAPERS
Key Excerpts & Legal Battle (1971)
Daniel Ellsberg · RAND Corporation · United States · June 1971
The classified history of US involvement in Vietnam that the government tried to suppress — and the Supreme Court case that protected the press’s right to publish it.
What Were the Pentagon Papers?
A 7,000-page classified study that documented 30 years of systematic deception.
The Pentagon Papers were a 7,000-page classified study commissioned in 1967 by Defense Secretary Robert McNamara. Officially titled “History of U.S. Decision-Making in Vietnam, 1945–68,” it documented 30 years of US involvement in Vietnam — and showed that successive administrations had systematically misled Congress and the public about the scope, progress, and prospects of the war.
Daniel Ellsberg, a military analyst at RAND Corporation who had worked on the study, leaked copies to The New York Times and Washington Post in June 1971. The Nixon administration obtained court injunctions to stop publication — the first instance of prior restraint against the American press in the nation’s history.
The Study
- Commissioned: 1967 by Defense Secretary McNamara
- Size: 7,000 pages, 47 volumes — all classified Top Secret
- Leaked by: Daniel Ellsberg, RAND Corporation analyst, to New York Times and Washington Post
- Published: June 13, 1971 — New York Times begins printing
- Declassified in full: June 2011 — National Security Archive FOIA release
What They Showed
- Four consecutive presidents escalated Vietnam while publicly claiming restraint
- Gulf of Tonkin Resolution was obtained under false pretenses — documented in the study itself
- Air strikes over North Vietnam were planned while LBJ publicly vowed not to enlarge the war
- Congress was not authorized — the War Powers Act would follow in 1973
The Papers — In Their Own Words
Key passages from the declassified study. Volumes I, IV, and the Summary Volume.
Volume 1 — The Truman Administration
1945–1952 · Origins of US Involvement
“The United States’ decision to provide military assistance to France and the Associated States was not primarily a result of French pressure but stemmed from US policy conclusions that the defeat of the Viet Minh was essential to US security interests.”
Volume I, Pentagon Papers — documenting that US involvement predated France’s requests and was driven by Cold War strategic doctrine, not allied obligation.
Summary Volume — Overall Assessment
1964–1968 · The Johnson Escalation
“The Pentagon Papers reveal that the Johnson Administration had secretly scaled up the conflict: planning air strikes over North Vietnam while the President was publicly vowing not to enlarge the war; planning the congressional Tonkin Gulf Resolution before the Tonkin Gulf incident as a pretext for escalation.”
Summary Volume, Pentagon Papers — the study’s own finding that the Tonkin Gulf Resolution was drafted in advance of the incident used to justify it.
Volume 4 — Lyndon Johnson’s Escalation Decision
1964–1965 · Doctrinal Justification
“A fourth objective was to contribute to the general containment of China... the doctrinal assumption... was that a Communist South Vietnam would trigger similar Communist insurgencies throughout Southeast Asia.”
Volume IV, Pentagon Papers — documenting that the strategic rationale for escalation was framed around containing China, not primarily defending South Vietnam.
Key Finding — Documented Throughout
1945–1968 · Four Administrations
“The study concluded that four administrations — Truman, Eisenhower, Kennedy, and Johnson — had each escalated US involvement in Vietnam while deliberately misrepresenting the situation to the public and Congress.”
Pentagon Papers, overarching conclusion — the study’s central finding spanning all 47 volumes. Declassified in full by the National Archives, 2011.

New York Times Co. v. United States (1971)
Prior restraint rejected 6–3. Six justices, six separate opinions. Decided in six days.
403 U.S. 713 (1971) — Decided June 30, 1971
6–3 For the PressThe Nixon administration obtained injunctions against both the New York Times and Washington Post within days of publication — the first use of prior restraint against the American press in the nation’s history. The Supreme Court took the case on an expedited basis. Six days after the case was argued, it was decided. The government’s argument: publication would cause “immediate, irreparable, and irreversible harm” and endanger troops. The Court found this insufficient to justify prior restraint.
Justice Hugo Black — Concurring
“In the First Amendment the Founding Fathers gave the free press the protection it must have to fulfill its essential role in our democracy. The press was to serve the governed, not the governors.”
Justice William Douglas — Concurring
“Secrecy in government is fundamentally anti-democratic, perpetuating bureaucratic errors. Open debate and discussion of public issues are vital to our national health.”
Justice Potter Stewart — Concurring
“The only effective restraint upon executive policy and power in the areas of national defense and international affairs may lie in an enlightened citizenry — in an informed and critical public opinion which alone can here protect the values of democratic government.”
Government Argument — Rejected
The Nixon administration argued that publication would cause “immediate, irreparable, and irreversible harm to the United States” and endanger troops. The Court held that the government had not met the heavy burden required to justify any system of prior restraint on the press — a doctrine that remains binding precedent.
What the Papers Revealed — The Legal Implications
Four documented consequences for US constitutional law.
The War Powers Problem
The Pentagon Papers documented that administrations made major escalation decisions — deploying hundreds of thousands of troops, conducting sustained bombing campaigns — without formal congressional authorization. The War Powers Act (1973) was a direct legislative response, requiring the President to notify Congress within 48 hours of committing forces and limiting deployments to 60 days without congressional approval.
The Gulf of Tonkin Problem
The study documented that the Gulf of Tonkin Resolution — the statutory basis for the entire Vietnam War — was obtained under false pretenses. The congressional resolution that authorized the war was drafted before the incident used to justify it. This is documented within the study commissioned by the Defense Department itself, not by outside critics.
The Ellsberg Prosecution — Dismissed
The Nixon administration charged Daniel Ellsberg under the Espionage Act. The charges were later dismissed — not on First Amendment grounds, but because of government misconduct. The same White House “Plumbers” unit that burglarized the Democratic National Committee headquarters (Watergate) had also broken into Ellsberg’s psychiatrist’s office in an attempt to discredit him. The judge dismissed all charges with prejudice.
The Prior Restraint Precedent
New York Times Co. v. United States established binding precedent on prior restraint: the government bears a heavy burden to justify any injunction blocking press publication. The First Amendment protection is not absolute, but the bar is extraordinarily high — the government must show that publication would cause direct, immediate, and irreparable harm. National security classification alone is not sufficient.
