Nuclear War: A Scenario

Annie Jacobsen

7 mins

What would the last seventy-two minutes of civilization actually look like? This microbook walks through the classified machinery behind nuclear war—the six-minute decision windows, the automatic protocols, and the chain reaction no single person controls. Drawing on decades of expert interviews, it reveals how catastrophe wouldn't need malice, only procedure already in place.

Who it is for

For those who assume someone, somewhere, would stop the worst from happening—and want to understand exactly how thin that assumption really is.

Key Insights

A bureaucracy that planned six hundred million deaths

In December 1960, defense official John H. Rubel attended a meeting at Strategic Air Command Headquarters expecting a technical briefing. Instead, officers calmly presented a plan to erase the Soviet Union and China with wave after wave of nuclear strikes, projecting 600 million deaths. Rubel later compared the meeting's bureaucratic calm to the Wannsee Conference. That plan became the SIOP—a master target list that no longer needed anyone's permission to exist, only a trigger.

The girl who survived what history classified

On August 6, 1945, thirteen-year-old Setsuko Thurlow was in a Hiroshima classroom when a flash of light collapsed the building around her. She crawled free from the rubble while classmates called for their mothers; outside, survivors walked with skin hanging from their bodies. Little Boy, a 15-kiloton bomb, killed more than 80,000 people instantly. The U.S. government later classified the blast's medical data, turning her city's suffering into a wartime data point.

The years-long winter no missile defense stops

The bombs are fast, but the aftermath unfolds for years. Scientists estimate global firestorms would loft roughly 150 teragrams of soot into the stratosphere, blocking sunlight and dropping temperatures below freezing even in summer. The ozone layer tears open, ultraviolet radiation surges, and marine food chains collapse. Crops fail worldwide, water systems turn unusable, and billions who survived the blasts starve—reducing surviving humanity to a hunter-gatherer existence within a single generation.

Lessons

  • Understand how automated protocols, not human judgment, drive the path to nuclear war.
  • Learn why deterrence is a psychological gamble rather than a guaranteed safeguard.
  • Discover what a nuclear exchange's aftermath does to climate, food, and civilization itself.

Key Takeaways

  • A nuclear war could unfold from first launch to final detonation in roughly seventy-two minutes.
  • The U.S. president would have only six minutes to authorize a retaliatory strike based on unconfirmed satellite data.
  • The climate effects of nuclear war—soot-choked skies and collapsing food chains—could kill far more people than the blasts themselves.
