Whither Iraq?

A friend asked me today what I thought we should do in Iraq. Answer: I think at this point we have a moral obligation to do whatever is best for the Iraqis. I have no idea what that is.

I therefore open up the floor to commenters. What should we do now in Iraq?

Update Please, please, please don't make me go in there and delete comments. I know you can do it if you try.
