"That is why Ronald Reagan supported him. Will Iraq be a secular state again?"
What is this, rewrite history day? Reagan "supported" Iraq (far less than just about every other country, BTW) insofar as he didn't want it overrun by ultra radical Iran--which has a population ten times its size and which was very close to winning the war against Iraq.
Sheesh.
So he did, for eight long years. Even to the point of sending the US Navy in 1988 (when the tragic shooting down of Irnanian airliner took place).
