I have no doubt chem weaps are being used.
The question is who is controlling them. It appears BOTH sides have used them, so attacking the Assad government for using them when previous attacks may have been made by the rebels is fairly absurd.
To compare what Hussein did in the '80s to what is going on in Syria now doesn't quite fit. Hussein eliminated close to an entire population. In Syria they are evidently being used in very small amounts, and they're using non-persistent agents where Hussein used persistent agents. As an illustration of how small the amounts they're using in Syria, a golf-ball sized dose of sarin dispersed in a crowd could kill thousands. (I'm assuming Sarin, seems to be the nerve agent of choice in the area, I'm not volunteering to go over with an M-256 kit and find out)
As to false positives in 2003, I'm yet to be convinced that the positives were false, too many dispersed incidents from soldiers in theater where agent monitors went off.
