If Iraq had established air superiority the war would likely have been concluded in a quick, victorious way for Saddam. As it were, the Iraqi air force lacked the heavy ordinance to destroy the Iranian air force's concrete hangars. Moreover, Saddam's forces should have been focus on Khuzestan and Khuzestan alone. In his historical battle plan at least part of his force was up around Baghdad where it had no earthly business. So these are two obvious PoDs. Now the first immediate consequence would be that Iraq isn't very damaged, allowing it to become a major regional power in the 80s and 90s. Whether Khomeini's regime falls is anyone's guess.
