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.

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].

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.

Well, it's a problem in general with the American military. If you are the biggest and the strongest military power in the world, you have this natural reluctance to learn the quirky ways of the natives in faraway lands.

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.

And if you look at the experience of Turkey, for example, where the modern Islamists are in power and are doing fine - this is very good. Because democracy is not possible in the Muslim world without bringing in the Islamists or part of the Islamists who hate us now into these governments.
