Polls of Iraqis consistently show that they want the U.S. out. Heck, even Maliki said so!
This attack may change their minds. Since it occurred in an area where there are very few, if any, Americans at all, it may give the Iraqis who want us out a taste of what would happen if we just packed up and left.
Source of that information?
I’m sure they’d love to have their country back to themselves, however, I’m sure they also understand that they have a lot more work to do before they can take that on. They don’t hate America; they just want their lives returned to some semblance of normal.
