Annie Jacobsen's minute by minute account of nuclear war

For many the prospect of nuclear armageddon subsided with the end of the Cold War, as the world's stockpile of warheads was diminished.

But Annie Jacobsen's new book challenges any sense of complacency over the possibility of a modern nuclear war. She is an investigative journalist and author, whose book The Pentagon's Brain: An Uncensored History of DARPA, America's Top Secret Military Research Agency made her a finalist for a Pulitzer Prize.

In Nuclear War: A Scenario she lays out, first in seconds, then minutes, what it would happen if North Korea launched a nuclear missile at the United States.

It's a sobering - yet fascinating -  read about where technology has led us - and the vulnerabilities we're all exposed to.
