That point is the confluence of terrorists, Ansar al Islam( Al Qa'ida), and CB weapons was a threat that had to be dealt with in Iraq."
There were several "salient points," even within the WMD category. It was also significant that terrorists proved themselves capable and willing to murder tens of thousands (remember that had the WTC been struck an hour later, and all 4 suicide flights successful, it's likely that 20,000 would have been dead).
In the light of this realization, and Saddam's uniquely supportive role of Islamicist terrorists ( ---alone among dictators of the world, Saddam financially supported religious terrorists, ---and openly boasted of it.), Bush decided to act. He was right then. He's right now.
I thought thats what I said. :-}
