I think the behavior of the troops has been a huge factor in the rise of the insurgency and in the rise of the anti-American feelings there[in Iraq].

Because no matter how much money we spend there [in Iraq], as long as the people there see this money as... as assistance that is unwelcome, as long as they continue to be humiliated in their own country by us... I mean, the future looked bleak, and the future after that was in fact very bleak.

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.

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

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.

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.

Long before 9/11 and the war in Iraq, a lot of people hated the United States and the West. But what the Iraqi war seems to have done, at least in... I mean, I'm just reporting what I see from the people on the ground, is that it has silenced many pro-American forces in the Muslim world.
