Not sure what story you are refering to, but I'm thinking it must be the Russian story that claimed it was the bombing of a nearby warehouse that had th chemicals.

When the initial reports of gas being used came out in i think Alepo, (Obama 'line' was crossed - or not), a significant group of conservative writers in this site said that it was the rebels that set off the chemicals and it was just a ploy to make Assad look bad.   

Isn't it funny how the bad guys turn coats when the American administration changed.    

I believe we are experiencing 'the fog of war'.     Lot's of second guessing, lot's of supposed reports and plots.    I'm not sure how one can say they have 'the truth' with a high level of confidence when it comes to information sources?
