Republican Presidential Candidate John McCain has a new book, Hard Call: Great Decisions and the Extraordinary People Who Made Them, in which he examines the most difficult aspect of being a Decider: making decisions. Written with Mark Salter, the book is largely anecdotal and offers numerous examples of good and bad decisions. During an interview with NPR, McCain drew heavily on history, citing stories from Vietnam and former presidents in an effort to explain how he came to make some of his hardest decisions, most notably his choice to support the Iraq war at its outset.

Of the current state of the war, which he also touches on in the book, he had this to say: “Every bit of knowledge and instinct, awareness and confidence that I have makes me believe absolutely that setting a date for withdrawal will result in chaos and genocide in the region, and we will then have to call on young Americans to make even greater sacrifices.”
