We are already well into the "Vietnamization" process in Iraq. By that I mean that the fight is being turned over to the Iraqi security forces. Anecdotal evidence suggests that some of these Iraqi units have already fought well even while taking significant casualties. It's becoming the Iraqi's war 'to lose'.
But the difference between Iraq and Vietnam is-WE CAN'T AFFORD TO LOSE!
It never mattered two sh*ts who ran the shi*hole in Saigon.
It matters, cosmically, if we are chased out of Iraq.
