Talking Peace With a Nuclear War Planner

An interview with 'The Post' whistleblower, Daniel Ellsberg.

Tom Hanks and Meryl Streep star in The Post, a film about the publication of the Pentagon Papers leaked by Daniel Ellsberg.

Daniel Ellsberg was an analyst for the Rand Corporation when, in 1971, he leaked top-secret Defense Department documents about the Vietnam War to The New York Times and other media outlets. The publication of what became known as the Pentagon Papers demonstrated, according to the Times, that the government had “systematically lied, not only to the public but also to Congress” about U.S. actions in Vietnam and escalations of the war into Laos and Cambodia. Ellsberg’s release of the Pentagon Papers is a central focus of the Steven Spielberg film The Post, starring Tom Hanks and Meryl Streep, scheduled for wide release in early January.
