Like some of the above had said. When I was there, they (Arabs) were friendly.
I'm sure after we are gone though--After US combat forces pull out, we are going to see a rise in sectarian violence.
Kurd, shia and sunni are all going to be waiting for the upcoming US power Vacuum when we leave.
Our friends in Iran are waiting to excercise their influence in the region also.
Look for violence to continue.
I think we should have left Iraq alone and gone after the Iranians. Iraq was the weaker of the two.

But I am only a 2 tour National Guardsman. What do I know.
