Ron Rosenbaum, in his fascinating and highly readable “How The End Begins” (2011) notes that when Kissinger told Nixon that Ellsberg was “the most dangerous man in America” he wasn’t referring to the Pentagon Papers but to what Ellsberg knew about top secret nuclear war plans from his work at RAND. Ellsberg had also made off with thousands of nuclear war-fighting strategy documents in addition to the Pentagon Papers, but decided to release the latter first. As it turned out much of the nuclear papers were lost during the turmoil following the Pentagon Papers release. This book, long overdue, is about what he learned then.
Ellsberg recalls being tasked to review the strategic war-fighting plans in effect under Eisenhower, and discovering that they called for “hitting every city, actually every town, above 25,000 population” in Russia and China and to some extent East Europe. Pressed for an estimate of death toll, the pentagon came back with 600 million dead. And that was not counting US and West European death tolls. “I thought, ‘This is the most evil plan that has ever existed. It’s insane.'”
Referring to US and Russian ICBM forces still to this day on alert: “Here is what we now know: the United States and Russia each have an actual Doomsday Machine.”
