Id rather they be tried and convicted like we did to the Nazis at the Nuremeberg trials, but I'll settle for them leaving, sure. Why must the Palestinians accept their presence when their entire presence was on the mass displacement and genocide of their people? They're not even sorry for any of it, they're literally doubling down on it all and continuing it on a scale never seen before.
Why are you so shocked that militia groups were formed to counter an oppressive genocidal colony? Also, keep in mind Israel literally helped prop Hamas up to delegtimize the Palestinians in the eyes of the international community. It just came back to bite them in the ass.
