War crimes and crimes against humanity cannot be ignored, and if nothing is done when a dictator uses chemical weapons agains their own people to maintain power, expect this to happen more and more frequently. After WW II it was shown that "just following orders" isn't an excuse and that has kept us far safer than any golden rule can. We can't charge them on our own, but it's time to dust off the old courtroom gavels in Switzerland, Sweden or the Netherlands, and start putting people on trial. If we wait till the end, what if it doesn't? And think of the lives lost waiting for an end to come.
