I was completely against intervention in Syria as much as the next guy but the use of chemical weapons can not be tolerated.
Even if it's proven that the "rebels" were responsible for the chemical attack?
There was a UN Chemical weapons Investigation team at a hotel 4.5 miles away at the time of the gassing of civilians in a neighborhood where the rebels were in the process of being driven out of an area they had previously taken control of. They were being beaten back badly for 36-48 straight hours at the time the gas was released.
With the UN inspection team right there in Damascus and the area in question being lost by the rebels badly, provide one palatable reason why the Assad government would choose that time and place to gas civilians in large numbers, with the eyes of the world more upon Damascus than at any time in the two-year old civil war
Then think about how much the "rebels" would have to gain by the very same action.
Sucker play all the way ...
