I'd venture to say that after us, the next folks that get shown the door will be the jihadis.... I don't think the Iraqis are going to go for their nonsense, and I think the Sunnis are going to want a piece of the new order. They have a lot to lose. With luck they'll get that settled without another Saddam taking over (Sunni or Shia). Let's not forget he was a cultural thing as well; he didn't happen in a vacuum.
Once we're gone though, the next proximate threat is the extremists. Watch.
The sitting ducks are really the people like you who think Teddy Kennedy, Durbin. Pelosi, Shumer, aren't aiding the Islamic facists in Iraq and elsewhere in killing US military and civilians everywhere. You people better decide who the good guys are!!!! We have met the enemy: Are you one of THEM?
