And here is your host, David Barr-Kirtley.

Hello and welcome to episode 297 of Geek's Guide to the Galaxy. Our guest today is Daniel Ellsberg. In 1971, while working

as an analyst for the Rands Corporation, he leaked the Pentagon Papers, which revealed that the

U.S. government had been lying to the American

people for decades about the Vietnam War, and those revelations helped bring the war to an end.

That story is told in the acclaimed new movie The Post, starring Tom Hanks and Merrill Streep.

And we'll be speaking with Daniel Ellsberg today about his new book, The Dooms Day Machine,

Confessions of a Nuclear War Planner, in which she reveals that in the 60s he was responsible

for drawing up America's plans for nuclear

war with the Soviet Union and China, and in which he also exposes the deranged thinking and total

lack of safeguards that have characterized America's nuclear war planning for generations.

And today's show is brought to you by Casper.

for a quality sleep surface with just the right sink and just the right bounce.
