Surging Ahead in Iraq: The new strategy can work. But Washington has to give it time

"If U.S. troops were to pull out anytime in the foreseeable future, the probable result would not be (as so many advocates of withdrawal claim) that Iraqis would "get their act together" and take care of their problems themselves. The far more likely consequence would be an all-out civil war. Not only would this be a humanitarian tragedy for which the U.S. would bear indirect responsibility, but it would also be a catastrophe for American interests in the region. If we are seen as the losers in Iraq, al Qaeda would be seen as the winner. The perception of American weakness fed by a pullout would lead to increased terrorism against the U.S. and our allies, just as occurred following our withdrawal from Somalia in 1993 and from Beirut in 1983.

In the ensuing chaos, it is quite possible that al Qaeda terrorists would succeed in turning western Iraq into a Taliban-style base for international terrorism. Although the momentum at the moment is running against al Qaeda in Anbar Province, the tribal forces who are now cooperating with the Iraqi government would be incapable of defeating al Qaeda on their own. If the U.S. were to pull out, the tribes would likely go back to cooperating with al Qaeda for the sake of self-preservation. And a handful of American Special Operations Forces operating from far-off bases would be helpless to stop the terrorists because they would lack the kind of human intelligence now generated by U.S. troops on the ground.

That is only one of many possible effects of an Iraqi civil war that we need to contemplate before making the fateful decision to give up the fight. Daniel Byman and Kenneth Pollack of the Brookings Institution, two serious Democratic analysts, issued a sobering study in January called "Things Fall Apart: Containing the Spillover From an Iraqi Civil War" that should be required reading for anyone calling for a pullout. Messrs. Byman and Pollack studied a number of civil wars stretching back to the 1970s in countries from Congo to Lebanon, and found that they are never confined within the borders drawn neatly on maps...

It's still possible to stave off catastrophic defeat in Iraq. But the only way to do it is to give Gen. Petraeus and his troops more time--at least another year--to try to change the dynamics on the ground. The surge strategy may be a long shot but every alternative is even worse.
