I really feel like, truly, some other country should do this if it’s deemed necessary by the international community. It would be better for the world at large. Making the US be the guy who shoots the gun isn’t good for anyone. If the UN wants to punish Assad militarily, then either the UN should do it itself or some other alliance of countries should. The US simply has far too much baggage and any attack from us gives a ready-made rallying cry for those we attack.
