Actions are evil, not people or nations. Raping, torturing, and murdering innocent civilians simply because of their ethnic identity is quintessentially evil. So is carpet-bombing whole cities where escape is impossible. Choosing sides in such a ghastly scenario of mutual hatreds and atrocities is simply stupid.
The only question worth asking—and I have no answer—is how to stop all this appalling bloodshed and hatred before it metastasizes into a global catastrophe.
