Assad got his gas shells from Saddam. Those are being moved around into safe Syrian controlled areas.
The rebels that use them on their own area in these very small scale “red line” incidents, (as in this story) get them from Obama and his Libyan operation in Benghazi.
Obama said Gas Use = US intervention. And presto*, suddenly the rebels are reporting gas attacks like this. LOL, it’s obvious.
So Hussein did have those WMDs!
