Assad's mother was a terror. He was terrified of her and she kept saying to him, you're not like your father. That's interesting, but it's useless information. It doesn't tell me anything about how the first and second armored brigades are going to operate.

When you're young and going to war, it's a genuinely exciting moment. You are going to risk yourself. On the battlefield, you are suddenly free. You realize: I'm here, I'm in it. Exaltation. Suddenly you're hit by another extraordinary feeling: my God, I can be killed. And: will I embarrass myself? It's like you're in a kaleidoscope and all of these extraordinary feelings are zipping by.

War is an extraordinary condition to be in - to be, for example, in the combat information center of a warship [and behaving] as though you were merely processing credit card applications. [Instead,] the information you're processing is that an incoming missile is 15 kilometers away, now 10 kilometers away, now 5 kilometers. You have to separate yourself psychologically from the fact that your mortal existence may well end. That is the ancient reality of war.

So as soon as you want something to happen you begin skewing the data to support it. Our stuff is invaluable to decision-makers precisely because we have no ax to grind.

I'm not a journalist. So I didn't down and let Assad charm me. I didn't walk away and say "my god he's got an Apple computer and he really likes Beyonce so he must be a liberal."

War to me is very much like sex. You can develop a theory that says sex is primarily for the exchange of genetic material, or that it's a celebration of life, or you can make up 50,000 theories about why human beings have sex, all of which are in some sense true, all of which by themselves miss the point. Because the answer is extraordinarily complex. It may be for fun, it may be for reproduction, for financial reasons, any number of things.
