If it Quacks like Uranium...

Just so there is no misunderstandings nor disavowals: Iraq did have nuclear material, 550 metric tons of "yellowcake" uranium, that is now being removed and sent to Canada. To us that is a substantial component of a WMD program. Why wasn't this fact mentioned a few years ago when the various Iraq review reports were being advertised as refuting the existance of a serious WMD program?
