And then, there's this.
Humans a failed experiment's final proof?
Maybe we should pre-engrave it on the planet, like a huge version of the Nazca Lines, should it be initiated, for whomever comes along.
The man who leaked the Pentagon Papers spent the rest of his life sitting on something far darker, and the book he finally wrote about it scared me more than anything I have ever read.
His name was Daniel Ellsberg. The book is called The Doomsday Machine: Confessions of a Nuclear War Planner.
Most of you know Ellsberg as the analyst who in 1971 handed 7,000 pages of classified Vietnam War documents to the press and almost went to prison for it. That story has a hero arc. A man of conscience, the system exposed, justice eventually served.
What almost nobody knows is what he did not leak.
When Ellsberg copied the Pentagon Papers at night on a photocopier borrowed from an advertising agency, he also copied something else. Thousands of pages about America's nuclear war plans. He had carried the same security clearance for both files. He intended to release them next.
He never got the chance. While the FBI was closing in after the Pentagon Papers went public, he transferred the nuclear documents to his brother, who buried them near a trash dump. A tropical storm hit. The papers dissolved into mud.
For decades, Ellsberg reconstructed what he remembered from notes, Freedom of Information Act requests, and interviews with people who had been in the same rooms. The Doomsday Machine is what came out of that reconstruction, and it is the most honest account of American nuclear policy that any insider has ever published.
The thing that hit me first is this: everything you believe about who controls nuclear weapons is wrong.
The official story, the one presidents repeat in press conferences and diplomats repeat in treaties, is that the American nuclear arsenal answers to a single chain of command ending at the desk of the President. The launch codes. The football. One person. One decision.
Ellsberg had a "go anywhere, ask anything" research mandate from RAND Corporation in 1959 and 1960. He traveled to air bases across the Pacific. He asked the question directly.
What he found was that the authority to launch nuclear weapons had been delegated far down the military hierarchy, to generals, to base commanders, to fighter pilots sitting in cockpits on remote runways. Not secretly. Not illegally. Deliberately. The military had decided that waiting for a presidential order in a world of supersonic bombers and thirty-minute missile flight times was tactically suicidal. So they had quietly built a system where dozens of people, in dozens of locations, could start a nuclear war on their own judgment.
The lock codes designed to prevent unauthorized launches at nuclear missile silos had been set to 00000000. All zeros. To make them faster to enter.
Nobody told the public. Nobody told most of the government. The President's control was, in Ellsberg's word, a hoax.
The second thing that stopped me cold was the plan itself.
In spring 1961, Ellsberg was at the White House when a general briefed Kennedy's national security team on what would actually happen if the United States executed its nuclear war plan against the Soviet Union.
The general showed a graph. The vertical axis was deaths. The horizontal axis was time, measured in months.
The curve flattened at 100 million Soviets dead from radioactive fallout alone. Not from the initial blasts. Just from the dust that floated back down.
Someone asked what would happen to China.
There was a second graph. China would lose roughly 300 million people.
When Ellsberg followed up and asked the total, accounting for fallout drifting into Western Europe, into neutral countries, into American allies, the number came back as approximately 600 million dead. In the Pentagon's own estimate. From a first strike the United States was planning to execute in response not to a nuclear attack, but to any conventional military confrontation that involved more than one American battalion.
Six hundred million people. A hundred holocausts, Ellsberg wrote later, by their own accounting.
And that estimate was made in 1961, before scientists understood nuclear winter. The actual death toll from the same strike, calculated with modern climate models, would have been the near-extinction of the human species.
The third revelation is the one that kept me awake.
The Soviet Union built a mirror of the same system, called Perimeter, sometimes referred to as the Dead Hand. It is a semi-automated retaliatory network designed to launch the entire Soviet nuclear arsenal if it detects that Soviet leadership has been destroyed and communication has gone dark. It was built to ensure that no American first strike could prevent retaliation.
It still exists. Russia never dismantled it.
Both countries built machines that can end civilization on their own. Both machines are still running.
Ellsberg spent the final years of his life trying to make people understand that the threat had not diminished, that the fundamental architecture of the nuclear age had not changed, that a fraction of the existing arsenals could still kill everyone alive today. He testified. He gave interviews. He filed lawsuit after lawsuit under the Freedom of Information Act.
He died in June 2023 at 92, still trying.
The strangest thing about the book is what it does to you after you put it down.
You go about your day. You check your phone. You argue about ordinary things. And somewhere underneath all of it sits this fact, verified and documented, that the species has built and maintained and continuously upgraded machines capable of ending itself, that those machines are controlled by systems far more fragile and distributed than anyone is allowed to officially admit, and that the people who designed them considered 600 million deaths an acceptable outcome of a conventional conflict.
Ellsberg called it ordinary insanity. Madness so widely shared, so institutionalized, that it stopped looking like madness at all.
He said that was the most dangerous thing about it.
The book is available everywhere books are sold. It will be the most important 400 pages you ever read and the most difficult ones to finish.
What book has genuinely scared you? I want to build a list.
