8613 Oklahoma City Bombs

From TAPPED:

[T]he lost material at [al Qaqaa] equals between 2,584 - 8613 OK City-size bombs. That's one hell of a lot of material to be on the street -- enough to fuel a car-bomb and IED-based insurgency for years, if not decades.

If the Army didn't have enough troops to secure this site, why not just call in the Air Force? I guess it might have caused a minor earthquake to bomb al Qaqaa, but wouldn't that have been preferable to 8613 Oklahoma City bombs, or one million Lockerbies, delivered one at a time?
