It seems that everyone but our Military and GWB have gotten the message that the only think these people understand is brute force.
I was pretty good pals with a retired Army O-4 while contracting in Iraq, and being that he was free of the chain of command he called it pretty much the way he saw it.
Let's just say his approach exceeded the merely severe, and he assured me that's what his still-active buddies thought as well (he was a West Point grad). They just didn't talk about it openly. Some of them are in Iraq right now.
As usual it's the pols who stand in the way of a quick and definitive solution to Iraq.
