How exactly do you fight a terrorist organization who uses children as both soldiers and human shields without any sort of civilian casualties?
Probably with more nuance than bombing entire neighborhoods...
Seriously, there is absolutely no possible ethical excuse for what Israel is doing. Right now the IDF is pretty indistinguishable from the SS. Genocide is genocide and Israel has come all the way from victim to perpetrator. The irony and reality of it is making the rest of the world sick, the only question is, why isn't it doing the same to the people of Israel?
