Almost everything about Afghanistan was troubling Mullen. As Obama was giving intense focus on the war, Mullen was feeling more personal responsibility. Afghanistan had been marked by 'incredible neglect,' he told some of his officers. 'It's almost like you're on a hunger strike and you're on the 50th day, and all of a sudden you're going to try to feed this person. Well, they're not going to eat very quickly. I mean, every organ in the body is collapsing. The under-resourcing of Afghanistan was much deeper and wider than even I thought. It wasn't just about troops. It was intellectually, it was strategically, it was physically, culturally.

I have written this book with the conviction that the response to injury does not have to be vengeance and that we need to distinguish between revenge and justice. A response other than revenge is possible and desirable. For that to happen, however, we need to turn the moment of injury into a moment of freedom, of choice. For Americans, that means turning 9/11 into an opportunity to reflect on America's place in the world. Grief for victims should not obscure the fact that there is no choice without a debate and no democracy without choice.
