Sorry, but the events in Iraq seems to be leading to a civil war with the US military smack dab in the middle. I think that is far worse than having a stable Iraq with the UN putting the resources in keeping tabs on Saddam than us trying to referee two sides ready to kill each other and have no wish to coexist.
I had no problems with the poicy on Iraq after the first gulf war. The threat was contained and Saddam was no threat to the US.
I don't particularly care about the long term. I care about our resource, money and manpower, being sucked in a vaccuum in which we had bo place being at. I wouldn't shed a tear if we pull out completely right now and set up containment on the borders and let the Iraqis have their internal war with each other.
