Some detail on the Sarin attack, from an ex-CIA analyst, published on the site of the guy who broke the Iran-Contra story. You won't have read how a Turkish MP proved in his parliament how Sarin gas was shipped to ISIS in Turkey, bacause apart from the Belfast Telegraph, no English language outlet reported the story. Obama 'pussied out' as you put it, because he doubted that Assad was responsible, and after Russia persuaded Assad to destroy all chemical weapons (this happened and Syria now has no chemical weapons).
