There were numerous connections between al Queda and Iraq going back at least 10 years. al Queda fled Afganistan for Iraq after our attack.
But the most significant reason we attacked was to prevent Saddam being able to develop WMDs. He had an entire nuclear weapons research program run in Libya which we did not even know about until Libya turned it over after the invasion.
For some strang reason this Treason Media COMPLETELY covered this up and refuses to investigate it or even discuss it. It never happened if we don't speak of it is their motto.
Even Dick (Dumbass) Clarke claimed Iraq and al Queda were cooperating in the chemical weapons program in the Sudan as did SecDef Cohen.
