Daniel Ellsberg is perhaps the premier whistleblower of all time, the man who in 1971 dragged the Pentagon Papers out of top-secret darkness into the light. Yet even as excerpts from the papers’ 7,000 pages were being published by The New York Times, The Washington Post, and other newspapers, Ellsberg was sitting on an entire second set of secrets, having nothing to do with Vietnam: all his material on nuclear policy, such as the operational plans for general nuclear war that he had drafted for the Joint Chiefs of Staff in his job as a RAND Corporation defense analyst.
