I'm begining to think you would like to see all the westerners out of Iraq and let that country fall into one giant civil war like what happened in Rwanda, Kosovo, or Sierra Leone. Nothing worse than a mother who can't hold her child because both limbs were hacked off at the elbow.
You've got a really short memory about what happened a year ago, in the hours and days after coalition forces took Baghdad, the Iraqi people basically looted everything that wasn't nailed down, and alot of stuff that was. What is your problem with western governments trying to make things better than when they were under the rule of Hussain?
What is the difference if they were private military contractors or a Chevy Suburban full of nuns, Either way I bet you probably would be dancing up and down like those savages in Fallujah in celebration that you just nailed a car with a RPG full of westerners.
If you have a problem with all of this, take your anger out on the leaders that started all of this, not the foot soldier, contractor, or aid worker trying to end all of this.
