The object is to achieve some sort of stable end-state which minimizes the likelihood of Iraqis’ killing each other in large numbers. That’s a pretty tall order.
If I were really President, I’d spend a lot of time first, talking with our military and intelligence people, getting more detailed information than I have now as a private citizen, and trying to get *them *to figure out a decent exit strategy that doesn’t take forever.
But if I have to come up with my own, on my own, with none of the special tools a President has at his disposal:
I think the way there is to tell them that we’re on our way out, and will be completely gone by March 2008; five years is enough. And that unless the warring parties can come up with some sort of peace deal on their own, we’re going to partition the country into Kurd, Shi’ite and Sunni parts, so they’d better get on with it, because we’ll use our air power to protect their country from foreign invasion (or from full-scale interfactional military actions) after we leave only if they come to a deal. Otherwise, we don’t mind terribly if Turkey grabs a piece here, and Iran takes a piece there, or if Sadrists and Badrists kill each other off while fighting over Basra.
My thought, or at least my wild-ass hope, is that that combination of facts and threats would get all the main parties to the negotiating table in earnest.
First of all, all the parties have something to lose from foreign invasion. The Kurds are most vulnerable, since Turkey and Iran could easily come to a deal to split up Iraqi Kurdistan; both feel threatened by the existence of a Kurdish quasi-state. The Iraqi Shi’ites, friendly though they may be with Iran, don’t really want to be ruled by non-Arabs. And even the Sunnis have to consider that Syria might grab much of western Iraq, even if it isn’t worth much, once Iran and Turkey were active in other places.
And the Sunnis, without a deal, have no oil, so they need a deal to keep them economically alive. The Kurds and Shi’ites still need us there to preserve some sort of order, in the absence of a deal.
So that’s how I’d do it: tell them to start dealing, or we start partitioning Iraq next June 30 based on the votes in the last election (since most parties were closely identified with religious/ethnic groups), with the partition to be complete by the time we leave on or before March 19, 2008. And if that involves drawing lines right through the middle of Baghdad or Kirkuk, well, so be it.
