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.

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.

But in Afghanistan, the general rule was that since you were fighting the Taliban, which was not a lawful government force, the Geneva Conventions did not apply. And that led to a lot of excesses in Afghanistan, excesses like Abu Ghraib that were already well-publicized.

So our own actions sometimes have undermined our safety, in our efforts to fight terrorism. The only way this can work is if we are aligned with liberals, with moderate Muslim forces. But if our war on terrorism is seen - as it is seen by many Muslims - as a war on Islam itself, it's very hard for us to have Muslim alliances, because America and the West have become so toxic.

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.

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.

Even if you look at Iran, those campaigners for human rights there, they don't want to have anything to do with America, because they are afraid that having American support will be the kiss of death for their movement. And that's really tragic.
