Of course we must constantly remind ourselves that "WMD" was always intrinsically somewhat of a bullshit argument. It should never have been whether Iraq had some nonconventional weapons, most of which aren't capable of "mass destruction," but whether Iraq was, through any means, a genuine threat to us. Absent an active nuclear program that really just was not the case, no matter how many nasty drums of chemicals Saddam had (or, apparently, didn't have) lying around.
