I'm not sure I'd ever make the statement "Saddam was one of the good guys to the USA in the 80's."
I had to do an oral presentation in college almost 20-years ago and I actually chose this topic. (Mostly because I was interested in how the Iranians were using the F-14 Tomcat as an AWACS.) Anyway, what I got from my research was that it's really more one of those situations where you don't want one side losing because it would create a vacuum in the region and thus the USA only supported Iraq in-so-much that it wouldn't be overthrown. Iraq was still mostly supplied with USSR equipment, look at what they used in the first Gulf War in 1991 if you can remember that. Though I think it really dumb of the USA to supply Saddam with biological warfare weapons to use just in case his country is starting to fall (and which Saddam immediatly used on the battlefield.) As a USA citizen, I will say that was dumb of us.
Iraq's air order of battle for 1985:
MiG19 (F-6, from China)
MiG-21, 25, 17, 23, 27
SU-7,20/22
Mirage F.1EQ, Super Etendard, Hunter, Gazelle, Alouette 3
Mi-4,8, TU22, TU134, Il76, Il28
That's most of it, I left most of the transport stuff out. It looks as though he was a "good guy" to France and USSR as well. I note no US aircraft in his inventory.
