I say this as someone whose family endured 6 years of Nazi German and Soviet crimes, including genocide, violence, rape, large scale looting and destruction of cultural heritage, and mass destruction of cities (85% of Warsaw alone was reduced to rubble, intentionally and systematically).

Why do I mention that? I mention that to underscore that just war is not utilitarian. You cannot justify Dresden or Hiroshima or Nagasaki. It doesn't mean you can't take strong measures, or that circumstances don't make a difference, only that the circumstances did not morally justify these acts. And it seems that the behavior of the Allies in Dresden and Hiroshima serve as precedent that is used to justify crimes like the leveling of Gaza and treating its civilians like cattle.
