"The Anatomy of Terror: From the Death of Bin Laden to the Rise of the Islamic State": I was happy that we finally got him. And a lot of my colleagues and friends that I know who sacrificed so much, some of them their lives, you know, finally can rest, knowing that he's dead. But also, at the same time, I kind of was troubled that we are now not fighting an organization anymore. The terrorists, the threat mutated to a message. Bin Laden accomplished something way bigger. He had a message that was spreading around the Muslim world.
On a good day, I view the job [of president] as directing an orchestra. On the dark days, it is more like that of a clutch -- engaging the engine to effect forward motion, while taking greater friction.
