Second reply; One of the posts above listed the agent as BZ. While not working on exactly the same methods you can think of it as an LSD gas. BZ is a nonlethal incapacitating agent. Assad wouldn’t be worried about using it in the least. It just makes the victims easier to shoot while they wander around absorbed in their hallucinations.
Well, honestly, doesn’t it all beg the question, if they haven’t used it before, whey would they do so now?
Sorry to say, and yes, I support Israel, but I’ll never support deployment of US Troops into Syria; its just another hopeless, unwinnable boondogle and I’m very suspicious of certain factions in Israel trying to trick us into doing just that!
