The Israeli state at least, like the German Nazi state during WW2, does deserve to be destroyed. Palestinians have had a life of continual murder from advanced weaponry at the hands of Israelis, but even they still generally don’t want to kill every Israeli person.
Mass killings of civilians were committed against Germany and Japan, and those attacks are widely seen as war crimes, most reasonable people don’t argue that the average German or Japanese worker going about their day deserved getting firebombed. There were mass atrocities but they weren’t defeated by genocide, they were defeated by a military campaign that took out any capacity they had to wage war.
