You're also making a big assumption ... that there were in fact WMD in Iraq prior to the start of the latest war. Saddam may have thought there were but seems that most of the evidence shows that they probably didnt exist. That doesnt mean that Bush was deceiving anyone. Even the UN folks thought Saddam was hiding something.
Everyone knew Saddam had WMD. The WMD certainly did exist the question is if they were destroyed where did their destruction take place?
Bush and Powell were totally correct in their statements.
Here is two possible scenario's.
1.Some WMD have been found, just not the quanity Saddam was supposed to have, so where did it all go?
2.The gov't is staying quite about WMD to find more.
Ya think by now we'd find some evidence of it either being destroyed or going somewhere. This WMD program Iraq had wasn't small and there is much that was not accounted for unless the UN and the rest of the world was lying about all those WMD.
