Yeah there was some talk about Iraqi air power before the first GW but not a one of their planes made it off the ground. We shut down any air threat immediately.
And because of the no fly zones we had most, if not all, of their AAA sites mapped and pinpointed. We do not have that luxury in Iran.
As a comparison, during the first gulf war (desert storm being the second) Iranian air superiority over the Iraqis was overwhelming.
