I'm going to go out on a limb here and say, in my humble opinion, it is Israel and the US that are behind this propaganda that we in the West are swallowing hook line and sinker.
I've spent the last few days reading about the background to this situation and it can be traced back to an agenda laid out by Israel and mimicked by the US industrial/Military Complex many years ago. The destabilisation of Syria is high on that agenda. The US component of this plan is evidenced/typified by the Daily Mail clip I posted earlier on in this thread.
The US have planned every detail and brought most of the plan to fruition. And I think Obama is aware of this, but it is too big even for the President of the USA to do anything except to go along with it.
IMHO of course.
