If we leave the region will deteriorate from chaos to regional war IMO. Saudi Arabia is not about to stand for Iran dominating the region and will oppose any move to consolidate power with the Iraqi Shia. In fact, with SA already pumping money to the Sunni in Iraq, if we leave, they will probably send in troops. It is my understanding that they have already begun building 75 miles of new paved road heading toward Iran. That would be for transporting military equipment no doubt. I just googeld this up.

Looks like the goalposts are moving on us again. This just keeps getting worse and worse. Now what?
