We owe it to the Iraqi people to do everything we can to help avert a civil war and give their fledgling democracy a chance. Saving them from themselves, however, is both beyond our power and responsibility. If they decide civil war is the only way to settle their longstanding disputes, we must stand aside and let them fight it and then try to salvage a relationship with the eventual victors. While that would be a bitter pill, indeed, after coming so close to achieving the incredibly ambitious vision of the neo-cons, it would nonetheless be preferable to the other alternatives.
I guess the “You broke it, you bought it” rule is no longer in effect.
