"There will, of course, be the Harry Reids and those on the far left who will deny inconvenient reality. Reid will continue to call the surge a failure, as he has since even before it began. And the left will continue to portray Gen. David Petraeus as an unscrupulous commander quite prepared to send his troops into a hopeless battle in order to advance his political ambitions (although exactly how that works is not clear).

But the serious voices will prevail. When the Democratic presidential front-runner concedes that the surge "is working" (albeit very late) against the insurgency, and when Petraeus himself concedes that the surge cannot continue indefinitely, making inevitable a drawdown of troops sometime in the middle of next year, the terms of the Iraq debate become narrow and the policy question simple: What do we do right now -- continue the surge or cut it short and begin withdrawal?

Serious people like Levin argue that with a nonfunctional and sectarian Baghdad government, we can never achieve national reconciliation. Thus the current military successes will prove ephemeral.

The problem with this argument is that it confuses long term and short term. In the longer run, there must be a national unity government. But in the shorter term, our assumption that a national unity government is required to pacify the Sunni insurgency turned out to be false. The Sunnis have turned against al-Qaeda and are gradually switching sides in the absence of any oil, federalism or de-Baathification deal coming out of Baghdad.

In the interim, the surge is advancing our two immediate objectives in Iraq: (a) to defeat al-Qaeda in Iraq and prevent the emergence of an al-Qaeda ministate, and (b) to pacify the Sunni insurgency, which began the post-liberation downward spiral of sectarian bloodshed, economic stagnation and aborted reconstruction."
