Don't underestimate the difficulty of targeting aircraft at such extreme ranges. I could get into all of the problems but let's just say there are many. Also, don't overestimate the ease with which we can develop and maintain the air picture, it's hardly a video game if your adversary has sophisticated jamming capability. Unlike the Iraqis, the Russians have put tremendous effort and resources into EW. It would not be Iraq again. That's not even considering the worst case scenario which would be the intelligent employment of EMP weapons.
