WAR IN IRAQ

The costs of America's abdication

Yes, it is true that there was no al-Qaida in Iraq when George W. Bush took office. But it is equally true that there was essentially no al-Qaida in Iraq remaining when Barack Obama took office.

Which makes Bush responsible for the terrible costs incurred to defeat the 2003-09 jihadist war engendered by his invasion. We can debate forever whether those costs were worth it, but what is not debatable is Obama’s responsibility for the return of the Islamist insurgency that had been routed by the time he became president.

By 2009, al-Qaida in Iraq had not just been decimated but humiliated by the American surge and the Anbar Awakening. Here were aggrieved Sunnis, having ferociously fought the Americans who had overthrown 80 years of Sunni hegemony, now reversing allegiance and joining the infidel invader in crushing, indeed extirpating from Iraq, their fellow Sunnis of al-Qaida.

At the same time, Shiite Prime Minister Nouri al-Maliki turned the Iraqi army against radical Shiite militias from Basra all the way north to Baghdad.

The result? “A sovereign, stable and self-reliant Iraq.” That’s not Bush congratulating himself. That’s Obama in December 2011 describing the Iraq we were leaving behind. He called it “an extraordinary achievement.”

Which Obama proceeded to throw away. David Petraeus had won the war. Obama’s one task was to conclude a status-of-forces agreement (SOFA) to solidify the gains. By Obama’s own admission — in the case he’s now making for a status-of-forces agreement with Afghanistan — such agreements are necessary “because after all the sacrifices we’ve made, we want to preserve the gains” achieved by war.

Which is what made his failure to do so in Iraq so disastrous. His excuse was his inability to get immunity for U.S. soldiers. Nonsense. Bush had worked out a compromise in his 2008 SOFA, as we have done with allies everywhere. The real problem was Obama’s reluctance to maintain any significant presence in Iraq.

Obama now has little choice but to try to re-create overnight, from scratch and in miniature, the kind of U.S. presence — providing intelligence, tactical advice and perhaps even air support — he abjured three years ago.

Obama’s announcement Thursday that he is sending 300 military advisers is the beginning of that re-creation — a pale substitute but the only option Obama has left himself. The leverage he forfeited will be hard to reclaim. But it’s our only hope.
