The other problem is that the priority of many soldiers in Iraq or Afghanistan is operational security: not getting killed. Now that is a very valid priority, but it has to be balanced against many other priorities, especially not killing too many locals in the process.

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.

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.

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.

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 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.

If you are an eighteen or nineteen-year-old with little education, as is often the case, and you're put in charge of many, many people on the other end of the world, you have absolute power and you're not prepared for it.
