Yea because Iraq was so powerful that it's front lines couldn't even cross a freaking road against Iran with 5 times the tanks force!!!!!!!!!!!! LOL!
And in Desert Storm Iraqi troops that were near the boarder and invading Kuwait gave up because they were carpet bombed by B-52's which had little to do with Iraqi SAM's!
And U.S. forces ran inside of Iraq and ran out quickly because they knew they wouldn't be able to hold those area's for long and the entire thing lasted about 100 HOURS! And they were mainly trying to get Iraq to fully withdraw from Kuwait while most of Iraqi armored battalion was deployed near Kuwait and coalition forces crossed miles of desert from Saudi Arabia and invaded and withdrew very quickly from the other side of Iraq!
U.S. bombardment started in January 17th 1991 and the war ended in Feb 28th 1991 with coalition invasion on Feb 24th 1991 & 4 day's later the war ended with a ceasefire after which U.S. came up with a plan to invade Iraq and came up with nonsense excuses to start bombing Iraqi Air Defense and military facilities and depots and that started in 1992 and went on to 2003 with a decade of bombings and sorties being flown 3-4 times a week until the U.S. felt confident enough to properly invade!
Since WW2 the U.S. has not gone to war with ANY country capable of producing a large portion of it's yearly military acquisitions let alone a country capable of targeting U.S. Aircraft bunkers from 700km away using it's own weapons
And your comparing Saddam's military where vast majority of it's weapons were purchased for them post 1982 by the Saudi's and couldn't even maintain the weapons given to them let alone produce new weapons and Iran was no different at that time we also had a nicely purchased Air Force, Helo Force and Navy we could barely arm and maintain!
In terms of military power the weapons platform you buy mean little unless you can maintain and arm them at will when needed and by 1979 Iran had purchased it's self one of the top 5 most powerful Air Forces in the world with one of the top 3 most powerful Helo Forces but without the U.S. providing parts, weapons and maintenance it didn't mean much because IF Iran could have actually maintained and armed it's own fighters and Helos in the early 80's the war would have ended by 1983 and Saddam's military would have been wiped and Saddam would have been killed or on the run!
And that was the lesson Iran learned so today Iran produces it's own weapons and imports little for it's military:

And that is real power and not fictional figures on paper that says you have this many fighter, Tanks, helicopters, SAM's....
