We're talking about the Iraqi people. If the mission is to overthrow Saddam, then once we have done so, he no longer relevant to the rebuilding discussion.
The iraqi people seem to be decision impaired. They've lived under tyranny for so long. We cannot afford to have to fight this same war every 10 years.
We free them, then teach them freedom retention skills. The un and other freedom destroyers would love for us to leave them room to move in. We cannot.
