Everything happening in Israel over the last 80 years is a pretty direct result of the Holocaust and WWII, which is what I mean by deferring problems. Jews were not a “problem” in any rational sense, and in no way responsible for WWII, but scapegoated and made a problem by the anti-semitic fascists. The immense collective suffering has shaped a lot of decisions and even now fuels the intensity of people’s reactions. It’s not going to be any different for any other victims of any other war.
But sure, keep telling yourself it was necessary to kill those people, to cause that trauma, that there’s no other way.
