All they had to do was comply with the inspections. Which, by the way, is why Blix is wrong and the Administration will be proven right. Why did Iraq obstruct the inspection process if they had nothing to hide?
Here's an allegory I used in a response on another forum.
See if it works for you.
(The kid and his toys part)
Think that even a liberal could understand it when put this way?
...12 years and many failed resolutions to prove that "weapons of mass destruction" (that IRAQ admitted that they had and were itemized at the end of Gulf War I) were destroyed under the terms negotiated back in '91.(Imagine that you looked in your child's room and saw all his toys on the floor. You say, "I want these all picked up....and DON'T JUST THROW THEM UNDER THE BED!" You come back in the allotted time....he cracks open the door and says, "See?" And you tap you foot and say, "Let me look under your bed", and he refuses....14 times.)
Since we cannot be assured of the destruction of what we KNOW he had (much less if he was producing more) and given that there are simple ways to reach this land(Anthrax....suitcase dirty nukes)and given that they had missiles that could reach Israel, we gave a final, no sh*t, final ultimatum.
He refused and the rest is history.
