I suspect part of the reason is what the source of these WMDs were, at least, most of the precursors: The west including the US. I also think it is somewhat amusing that although Iraq was for a long time in the Soviet orbit, none of the WMDs were traced, from what I see, back to the USSR. I could be wrong on that but it seems correct from what was posted.
Well that’s one story that would seem to jive with a possible motive for the inexplicable actions, if all this is true.
When this story first broke the first thing I thought of was the truck convoys into Syria and how no one really made a big deal about them. I found this article which alleges Russia facilitated the possible removal of the current WMDs before and during the invasion.

He either approved or had a motivation to just let it go because it wasnt actually a big deal to him, or had knowledge that there wasnt really anything to it.
Now we have to invade Syria to get the WMDs that were moved there might have been politically and militarily counter productive to what he was trying to do in Iraq?

Maybe they kept it silent because of who sold the weapons to Saddam. Who was president when Saddam purchased them? mmmm
