Of course he will use them. His predecessor used them in Hom to control a revolt by the Muslim Brotherhood a few decades ago. The defector who claimed that Assad was joining forces with al Qeade, kinda ridiculous, but he also claimed there is evidence Assad has already used chemical WMD in Hom. Do not believe that and think everything that defector said was pre written by the those funding and supporting the insurgents (IE - House of Saud, Turks, NATO, Obama and Hillary).
The plain fact of the matter is the pentagon must be blowing a top right now. This battle plan for Syria is absolutely insane. Its as if the Pentagon put together a few plans, they had to include all options, and Obama choose the one that was just put on the table because all options had to be shown. No one probably thought any one with half a clue would have selected this battle plan.
We didn’t stop Saddam from gassing his own people and we won’t stop Assad either. Not without Comrade Putin’s permission.
