The far right in Israel has a lot to answer for. There is no doubt that the actions of Israel in Palestine created Hamas. I think it's too far of a jump to say this is intentionally creating a justification for genocide. It's also important to acknowledge that the government in both countries doesn't represent all of their people. There are genocidal assholes on both sides as well as those who want to coexist. I would prefer that Israel didn't exist at all because any religious or ethnically exclusive country is troubling to me, but the Nazis didn't leave us much choice.
