Russia was supporting Assad .. and if Assad did have the WMD, then Russia would have been willing to challenge us for possession of the WMD.
And .. if anybody remembers, at one time Assad had used chemical gases on his own people; which some believed established that Syria did have the WMD from Iraq..
But in any case, if Bush was willing to lie to not rat out the Russians for giving the crazy Muslems WMD, why wouldn’t he have just created some evidence or story or whatever about WMD in Iraq?
