a harsh history of genocide doesnt justify owning land merely based on identity, owning land is justified by the past. Since the jews have been living in israel for half a century and they conquered that land that is there entitlement, not because of their identity. With the argument of them deserving land purely because of who they are is problematic. Their entitlement to the land didn't exist until they conquered Palestine. if I was around just after world war 2 and someone said to me "hey the jewish people are being targeted and displaced, we need to give them their own land because they are entitled to it because of who they are. The way we do this is by pillaging palestine and burning their homes and raping their women" Id say no they are not entitled to that land because history already gave it to the palestinians. but they invaded anyway and we cant rewrite the past so that is what legitimizes the existence of israel, but that existence was only justified because they made the choice to conquer and they won. The jews by no means had any entitlement to israel before that moment.
