Nazi's wanted an ethnostate, so to show the world how different they are, Zionists did the same. Everything else you said in this paragraph is irrelevant and has no connection to anything. You just tried to fill space.
Saudi Arabia weaning itself off oil has literally zero connection to being more peaceful. If anything, Saudi Arabia is LESS peaceful under MBS. They bombed the shit out of Yemen when Saudi Arabia hadn't been involved in a war for decades prior to that. MBS government was also involved in the escalation of the Qatar diplomatic crisis, the 2017 detention of Lebanese prime minister Saad Hariri, a 2018 diplomatic spat with Canada, the arrest of Saudi princes and billionaires in 2017, the 2018–2019 Saudi crackdown on feminists, an alleged phone hack against Amazon chairman Jeff Bezos in 2019. By what logic is Saudi Arabia moving towards being more peaceful? You just spout off nonsense without any knowledge of political affairs.
Also even if that were the case, BY WHAT LOGIC would the other Arab State's follow Saudi's lead? You think other Arab countries get along with Saudi? LOL! You don't know anything.
Other Muslim States haven't done shit to help Palestine since the war of 1948 so nothing has changed there. And there has never been a chance for peace and prosperity. Israel has never offered the Palestinians a fair deal, and even when they accepted bad deals, Israel never honored them and has been continually, illegally, encroaching on Palestinian land for the last 50+ years.
What I think is that nothing will change until Israel embraces a one-state solution. Until then the fighting and killing and oppressing will continue until maybe someday a foreign power invades Israel for whatever reason.
