In the occupation in Afghanistan, there are tragedies as well. It's not as bad as in Iraq because there are fewer American troops. But, as I describe in the book, going out on patrol and coming into a village, the soldiers found a stash of documents and decided this was Taliban propaganda.

Even if you are a liberal in the Muslim world, when you see Abu Ghraib and Guantanamo, and you see all the other reports of abuses by American forces, it's very hard to get up and say, "We should simulate the American ways," because this is the face of America now in the Muslim world, for many Muslims.

Now as to the behavior of the soldiers: occupations always corrupt the occupiers.

I did some embedded stuff. And if you are embedded, the only things you see are what the soldiers see, and if the people talk to you, they talk to you as if you are a soldier, because with your flak jacket and your helmet, they can't tell the difference between you and the soldier next to you, and they obviously won't tell you what they really think because they are afraid of you.

I think in Baghdad, any westerner, journalist or not, has a big dollar sign on his or her forehead. So, first and foremost, you are a ticket to unimaginable wealth. And that makes any trips out of the safe zones very risky.

The rules of engagement are so lax that soldiers are shooting and killing Iraqis under mere suspicion, and tragedies are everyday. There are road killings, killings on the road when someone is trying to pass a convoy and they get shot. Or if a roadside bomb goes off, the soldiers just start shooting in all directions.

In a country like Iraq with its culture of blood feuds - is that the more locals are killed, the more motivation there is for the insurgency, for the insurgents the more feelings of revenge there are, and in the end the more the operational security of the soldiers suffers, because any soldier who kills an infant today is grooming the killer of his mate tomorrow.
