The only problem with that course of action is that it would result in control of Iraq, save Anbar and the Kurdish north, by the Shiite Militias, who are allied with Iran, and who would make their part of Iraq into what Afghanistan under the Taliban was, only 10 times over. Similarly the Sunni controlled areas would be havens and training grounds for Al Qaida.
We, including your son, would have to be killing them here, rather than there, with much additional loss of American civilians. Your son, signed up to prevent that sort of thing. All who ever signed up did that, including this old man.
That's true. But, more and more our troops are thinking longer and longer before engaging the enemy now in Iraq out of fears of being charged with murder by our own government. That's where I (a supporter of the WOT (including Iraq)and the invasion of Iraq) draw the line.
I say let our boys do the job and KILL the enemy or bring them home
