Saint Frank’s column today notices how we are all turning our back on Iraq, even the most passionate among us. But it’s not sustainable.

General Petraeus and Mr. Crocker define victory as “sustainable security” in Iraq. But both Colin Powell and Gen. Richard Cody, the Army’s vice chief of staff, said last week that current troop levels in Iraq and Afghanistan are unsustainable and are damaging America’s readiness to meet other security threats. And that’s not all that’s unsustainable. An ailing economy can’t keep floating the war’s $3-billion-a-week cost. A Republican president intent on staying the Bush course will find his vetoes unsustainable after the Democrats increase their majorities in Congress in November. No war can be fought indefinitely if the public has irrevocably turned against it.
