If we were to leave Iraq before the Iraqis were able to take care of business by themselves, and the thugs/terrorists (I refuse to call them "insurgents") staged a coup, the kool-aid drinking barking moonbats of the loony left would be the first to crow that the big bad United States had been defeated.
Once we put all the terrorists Tango Uniform in Iraq, there is some business here at home to be tended to. When we put the loony-tunes nutcases of Code Pink and other subversive groups in Gitmo, let's make sure we give them cold MRE's and no showers. Not that they take showers anyway.
