I think you missed my point, which was this stuff has been used in weaponized, aerosolized form for 85 years and has killed and injured 100s of thousands, if not millions. These are fearsome weapons if used properly, especially on unprotected troops and/or populations.
But chemical weapons are not new. Anybody with access to the basic chemicals and a way to combine them and distribute them can be a player if they are willing to take the risk. Low tech cropdusters or numerous other easy, cheap distribution systems are readily available to the imaginative.
Chemical weapons are not new, and it should surprise absolutely nobody that bin Laden and his buddies have them and are testing them to make sure they work. There are a number of nasty countries who could - and maybe would - pass this stuff on to him, all ready to go. The fact we have footage of them testing the stuff is surprising only to Liberal TV viewers, who invariably live in a dream world and think "it can never happen to me, after all, I'm a very special people!".
One thing is for sure; showing this test on national TV might concentrate the minds of a few of these naive naysayers and let them reflect on just who the bad guys are and what they may have in store for us. Liberals can die agonizing deaths, just like Conservatives, if TSHTF. There are numerous more pleasant ways to die than puking yourself to death, having your skin burnt off, feeling your mucous membranes disintegrate, being painfully blinded and drowning in your own mucous, or merely suffocating in twisted agony.
This is scary,... but not surprising.
