How could a "Weapon of Mass Destruction" not be "weaponized?" Biden's remark is an oxymoron.
Dunno.
It's intellectual dishonesty of the type that gave us "That depends on what the meaning of the word 'is', is" and "No controlling legal authority".
Biden has to ignore the fact that international agreement and consensus since pretty much WWI states that Sarin is a WMD.
It's internationally stated an ddefined as such.
So Biden has to be either insane, stupid, or simply ignoring fact to fit an agenda.
