I think you’re dead on the money on all points.
I’d like to add that WMD could mean many things... Generally speaking I would say MASS destruction weapons like bio, chemical, nuke.
Iraq really didn’t have anything I would classifying as WMD, but they did have gas shells and they were working on creating big boy weapons, but not for use on us, but for their regional foes.
Ugh... Iraq was a mistake.
This Gov has redefined WMD as fire crackers in a pressure cooker
