ay schifrin: paul saunders, was tod response appropriate?i think it's entirely appropriate if u.s. government knows what russia is guilty of the poisoning. what is not yet clear from the information, athletes that's been released to the public, is how certain we really are, and i would point by way of explanation to actually -- of what i mean, a press release from the state department last week about the designation of a french national as a terrorist in syria, and this man was designated as a terrorist because he was allegedly producing and helping i.s.i.s. to use chemical weapons on the we were told for seven years every team chemical weapons were used in wria that ths done by the assad regime because no one else had the capabilitto use chemical weapons. now, we're hearing from our own state department that, actually, other people, including i.s.i.s., have the ability in syria to useca che weapons. the reason i give this longis storust to illustrate that determining whis doing what with some of these agents is not always the easiest thing.
