"Nuclear War: A Scenario" is a book about the scarcity of time, forcing readers to reflect on how close the world is to nuclear catastrophe. According to the vision presented by the book’s author, Annie Jacobsen, it becomes clear that in the event of a hypothetical nuclear conflict between the United States and North Korea, a global nuclear disaster would conclude within an hour.

Jacobsen’s depiction of the world paints a grim reality, showing readers what we should expect if the hands of the Doomsday Clock ever strike midnight. In shocking detail, the author describes how the world would be reduced to ashes in just 72 minutes.

When one considers that space-based infrared satellites can detect ballistic missile launches within seconds, and a North Korean intercontinental ballistic missile (ICBM) would take roughly 30 minutes to reach its target, the U.S. president would have only about six minutes after receiving a nuclear attack notification to launch around 400 Minuteman III ICBMs. The author divides this nuclear conflict scenario into three 24-minute segments, demonstrating just how little time it would take to turn "human genius and ingenuity, love and desire, compassion and intellect into ash."

On the eve of the 80th anniversary of the first atomic explosion in the New Mexico desert—followed three weeks later by the first and only wartime use of nuclear weapons by the United States against Japan, namely the civilian populations of Hiroshima and Nagasaki—this book lays bare the horrors of nuclear war.
