Just ask the Iraqis how hard it is to maneuver mechanized columns under air attack. They got a hard lesson in 1991 and as a result they hardly even tried to do so again last year. I am unconcerned that whatever force the jihadis could muster would be able to even come close to conquering our allies in the region.
We are talking about some rinky dink countries. They could get tanks from the border to the airports inside of 2 hours. That is a far cry from manuevering against major US forces in central Iraq. I don't doubt that the air force could inflict damage. I do doubt they could stop them. The air force's best capability is against soft logistic targets...they wouldn't even need to bring logistics to the fight...it would be over before they needed gas. The Air Force just isn't very good at killing tanks except for A-10's, which are very vulnerable to SAMs. At least enough tanks would make it to the POMCUS and air bases to devastate whatever is there.
