Sounds alot like Vietnamization, really.
But it makes sense. That was the plan from the start. Get the dictator out, remove the powerbase, and turn the country over to the Iraqi's.
Sooner or later, hopefully sooner, the only US troops in Iraq will be reaction forces.
It did not work in Vietnam because of the politicians of the era, namesly LBJ and McNamara.
I am sure GWB and co. can do better.
