That is as braindead a statement as has ever been made about the occupation of Iraq.
You pretty much don’t have even the slightest smidgen of a clue about the dynamics of the area.
Troops in Iraq were never going to accomplish anything in Iraq that would last past the day we left because the rules of engagement and the political constrictions were not designed to accomplish that. So it was impossible to pull out too early since we weren’t doing the job required in the first place.
