I have read it twice and have purchased copies for others. It is compelling, mind-blowing and terrifying to think we could face this. The potential for dithering when minutes count, the unpreparedness of the chain of command, and heads of state refusing to take calls due to past insults or lack of protocol is sadly believable. The long memory of the Korean president over the perceived insult when the two Koreas were publicly compared and his potential to destroy our entire electrical grid is what nightmares are made of. Every government official should read this.
