I agree that we should at least get some form of evidence of who was responsible for the chemical attack that can be proven. Assad has a really bad reputation so that kind of goes against him. I've met some of the "Rebels" before and I can't see them gassing their own area or making chemicals. It's too dangerous for them and for the civilians. Maybe it was another faction that made the chemicals and got bombed, or maybe a cmdr planned it with out Assad knowing or maybe Assad did do it.  I've been in Syria when they dropped barrel bombs not sure if they were aiming for ISIS or the "Rebels" or both but Assad's military hit neither. Only civilians died. Once finished ISIS showed up within 10-15 min. They didn't last very long btw they got hit quick. Made me smile. I agree to the missile strike only if Assad's airforce was the culprit. Believing they were isn't the same thing. Also I still approve of Tulsi talking to Assad. Though supporters, many Alawites are tired of burying their sons.
