Iran-Iraq air war

Im sure Iraq thought they would have an easy win in this war considering embassy hostage crisis would make it impossible for Iran to wage war with all american weaponry. But Iran was able to inflict heavy damage with their air force particularly against the initial armored invasion force. If the hostage crisis did not happen and Iran was able to get spares and resupply for its military it would appear that Iran could have overwhelmingly defeated Iraq in the war. Im wondering what opinions here are on the Iranian and Iraqi air forces during this war.
