IMHO the rebellion against Assad doesn’t seem to going as well as the (terrorist) “err” rebels expected and some outside intervention is needed. What better way to draw the westerners into delivering some free airmail to their enemy than to stage a convenient atrocity. The Brits aren’t buying it but BHO seems to be taking the bait hook line and sinker.
Obastard doesn’t care if the intercepts are true or not. He just wants an excuse to bomb Assad.
