On this edition of Your Call, we remember Daniel Ellsberg, the Pentagon Papers whistleblower who exposed the truth behind the Vietnam War. He died on June 16 at the age of 92.

We listen to our 2018 interview with him about his book The Doomsday Machine: Confessions of a Nuclear War Planner in which he documents the development of the US nuclear war plan and the flaws that make the system so unstable and dangerous.
