I'm pretty sure there isn't many Americans who would say that they want to keep troops in Iraq. It's rediculous to think that anyone would.
The fact of the matter is that if we just up and left there would be a power vaccuum and Iran would move in even more than they already have.
We are providing stability in the area right now. The Iraqi government needs to get off its ass and build themselves some legs so we can take ours out and the government not fall over.
