In Nuclear War: A Scenario, Annie Jacobsen posits how a nuclear attack on the United States by a rogue nation might play out, requiring a response that draws in other countries until over half of the planet’s population is killed and most of its landmass is left uninhabitable in less than 24 hours.  It is based on interviews with the scientists and policy makers that have insider knowledge of the protocols in place, both here and abroad, and is frightening on how precarious peace and survival is.  An interesting, if downright terrifying, read, especially given some of the current players who have their fingers on the proverbial triggers.
