this is not US responsibility, this is a violation of INTERNATIONAL LAW (not just one country is violated) Therefore, the UN is the one in charge and responsible for coming up with the consequences of whoever used chemical weapons and also responsible for ACTING out said consequences ie. charge assad w/ war crimes, locate and disperse chemical weapons, etc. This is not solely up to US to take action and kill more innocents via a missile strike. Let the UN do it's job!
