Imagine, if you will, that for unknown reasons North Korea has just launched a nuclear bomb at the United States. What happens next?

The journalist Annie Jacobsen has imagined exactly that, and spent more than a decade interviewing dozens of experts while mastering the voluminous literature on the subject — some of it declassified only in recent years — for her 2024 book “Nuclear War: A Scenario,” which walks readers through the 72 minutes from launch to global annihilation. In the Book Review last year, Barry Gewen said the book was “gripping,” and declared it essential reading “if you want to understand the complex and disturbing details that go into a civilization-destroying decision.”

This week, Jacobsen visits the podcast to talk about her book and why she wrote it, as well as offering some hope that catastrophe can be avoided. “I wanted to write a book that showed in absolutely appalling detail how horrific nuclear war would be,” she tells the host Gilbert Cruz. “And so when people say to me either ‘I could barely read your book, but I had to read it.’ or ‘I had to read it in one sitting, I was terrified, I was horrified,’ I believe I did my job.”
