Earlier quoted context omitted.
I always see this is trotted out as to say that Iraq did not possess WMDs, however technically it is wrong, as WMDs (chemical weapons in this case) were found after the invasion, (see https://en.wikipedia.org/wiki/Iraq_and_weapons_of_mass_destr... ). While there was no evidence of nuclear weapons or an active program I believe that a better quote should be used since the pretences that it is quoted for are technicall…
Of course, because WMD is a manufacturered phrase with tautological utility. A kitchen knife wielded in a sinister way is capable of mass destruction.
There are always people trying to expand the definition, but it's usually from more left-leaning critical schools of thought that want to classify landmines, sanctions or guns as WMD.
But in official usage, it's been pretty stable at those three.
