Saddam Hussein was trying to obtain WMDs. That is very clear. He was prohibited from obtaining such weapons from the “peace” agreement after the 1991 Gulf War.
He essentially “violated parole” and broke the peace. It was for this that he was deposed.
Saddam used chemical weapons on the Kurds and the Iranians. What else does anybody need to know?
There were WMD’s in Iraq.
That aside, yes, oil is indeed a good reason to go to war (as long as we refuse to drill it ourselves).
Oil= jobs= medicine= food.....
