Six minutes to decide: how close nuclear war really is
September 29, 2026 · 19 min read
Annie Jacobsen's minute-by-minute scenario, Mearsheimer on the manipulation of risk, Gabbard on courage in the room and Musk on nuclear escalation all stress how little time and how few safeguards exist. It reframes nuclear risk as a live, present danger rather than a Cold War memory.
The rules, numbers and steps worth keeping in front of you.
- Annie Jacobsen: after a confirmed warning, a U.S. president has about six minutes to decide whether to launch.
- Sole presidential authority: the president asks no one's permission, not the defense secretary, the Joint Chiefs or Congress.
- ICBMs and submarine missiles cannot be recalled or redirected; bombers can.
- Flight time: 26 minutes 40 seconds from a Soviet launch pad to the U.S. East Coast; under 10 minutes from a submarine near the coast.
- The U.S. has 44 interceptors, and they work 50 percent of the time.
- Deployed weapons: 1,770 U.S. and 1,674 Russian, able to launch in as little as 60 seconds.
- Jacobsen: a U.S. and Russia nuclear war could ultimately kill five billion people.
- False alarms happen: in 1979 a training tape nearly triggered a warning to the president.
- In November 2022 General Mark Milley could not reach his Russian counterpart for 36 hours.
- John Mearsheimer: a losing side might explode a few weapons to manipulate risk; nobody knows the escalation dynamics after that.
- Mearsheimer: nuclear weapons make great power war much less likely, but not impossible.
- Tulsi Gabbard: reject talk of tactical nuclear weapons as just another tool; a nuclear war cannot be won.
- Elon Musk: the probability is quite low, but it is a civilizational threat that should outrank local concerns.
- Brian Toon, via Jacobsen: unlike an asteroid, nuclear war is something we can do something about.
