Hundreds of deadly missiles streaking through the air from silos and nuclear submarines.
American cities burning and millions vaporized, instantly, with millions more soon to die in agony from burns and radiation poisoning.
How it could happen in a matter of minutes is the subject of the new book Nuclear War: A Scenario, by Pulitzer-nominated investigative journalist Annie Jacobsen.
The chilling play-by-play is based on exclusive interviews with high-ranking military officials, political figures and leading experts including nuclear weapon designers.
It takes about 30 minutes for an ICBM (intercontinental ballistic missile) to travel from one side of the world – say Beijing, Moscow or North Korea – to another.Â
America, under the sole authority of one person, the president, would then launch a counter offensive. Chillingly, she says it would take just 72 minutes to wipe out five billion people if the worst comes to pass.

Jacobsen writes: ‘A nuclear strike on the Pentagon is just the beginning of a scenario the finality of which will be the end of civilization as we know it.Â
 ‘This is the reality of the world in which we all live. The nuclear war scenario proposed in this book could happen tomorrow. Or later today.’
She adds: ‘On top of the initial flash of thermonuclear light, which is 180 million degrees, which catches everything on fire in a nine mile diameter radius; on top of the bulldozing effect of the wind and all the buildings coming down and more fires igniting on top of the radiation poisoning people to death in minutes and hours and days and weeks, if they happen to have survived, on top of all of that, each one of these fires creates a mega fire that is 100 or more square miles and so.’
The author said if the world went into nuclear war you would ‘want to die instantly’ because ‘there is no more law and order.’
The book includes interviews with former U.S. Secretary of Defense Leon E Panetta, and Robert Kehler, former United States Secretary of Defense, along with former senior commanders from United States nuclear forces.
This, according to them and others, is how it could happen:Â
