“I think if Thomas Jefferson were looking down, the author of the Bill of Rights, on what’s being proposed here, he’d agree with it. He would agree that the First Amendment cannot be absolute.” - Chuck Schumer (D). Yet, Madison and Mason wrote the Bill of Rights, according to Sheila Jackson Lee, 400 years ago. Yup, it's a fact.
Which Kerry better not commit us to that action. Plus no one is going to just accept Russia's word they on they will do it.
But, among the OSCE members, there was always 1 guys missing! That day one would not join the group. The missing also always changed so as not to draw suspicion. One day a guy from one group was missing the next day he/she was back but another guy would be missing. Upon question they would state trivial causes: Working some back home, sleeping, he will be back tomorrow, etc.
So if you think that the crew will go through an entirely scheduled procedure from Syria then you are wrong. Some who may be missing might go and take data their own way. Not to mention that some may be spies to begin with .
Now this is what we know as civilians. Who knows how much more there may be to it!
Moreover, there would be of-course spies and there would be other people working on the subject of WMDs in Syria, as there are today.
However, again it has nothing to do with what these investigators would be able to uncover under the guidelines of their mandate - that would probably be to monitor and assess the declared Syrian chemical sites.
PS. You give too much credit to the capabilities of the various intelligence departments, including CIA.
PPS. What makes you think there are other WMDs in Syria - i.e biological, nuclear?
Biological ones though, they are not far from chems I think.
