Shia Twitter was bricking it last night about Damascus being flattened (Iran had supposedly evacuated its diplomats), or their entire air force being taken out, so this seems like a bit of a gimmick 'Don't do that again!' attack at the moment. As for the actual chemical attack, I don't want to get into FALSE FLAG territory, but it seems a bit convenient. The day after the Americans shift policy, and the day before a UN meeting, the government decides to drop some of the chemical stocks it had previously agreed to destroy (and had officially done so) in order to avoid an American intervention on a village of no consequence when it is winning on all fronts and just as the major opposition counter-offensives grind to a halt. Whatever you make of these people, they clearly aren't absolute idiots.
