On the plane from Georgia to Paris I sat next to a Colonel in the U.S. Army. He was going back to Iraq for the third time. He doesn't support the war, and he doesn't trust his government. He is going to speak reason and keep his troops away from unnecessary harm.
He has no problem "killing Iraqis."
He crosses himself upon takeoff and landing.
Several of his men were killed by a shot from a pistol under the back of their helmet as they walked through crowded streets.
