the old chemical weapons trick

I see the media and the US are back on the chemical weapons claims against Syria. This is the third time this stunt has been raised, I am sure the US and Israel thought that Assad would have been toppled by now.
I think the world is waking up and the countries like Russia and a China are no longer bending over like they used to. The days of the US as power house are coming to a close; talk that $U.S. is doomed, get on Gold!
