Thanks! I mentioned some of these topics in the appendix. I didn't want to make it too long so obviously I skipped many details.

Re. 1 - I am pretty sure most Mizrahi Israelis don't really want to move back to their countries of origin... but in many cases they had to sign over their property to the government in order to leave. I don't believe they'll ever get it back.

Re. 2 - A one state solution is not possible, IMO, for a number of reasons, not the least of which - if we don't get along when we're not in the same state, how are we supposed to get along in the same state? I also think the "one state solution" proposed by the Israeli far right - annexing the West Bank but leaving the Palestinian stateless, is morally wrong and is bound to backfire. This is why the 2-state solution is the only moral one (albeit also not very feasible). An Israeli journalist recently called it "an amicable divorce". Oh, and fun fact: The vast majority of Israeli Arabs would prefer to stay Israeli even if there was a Palestinian state. They may not be very happy with the Israeli government and with being a minority in a Jewish state, but they are not stupid.

Re. 3 - no Arab country wants to take in the Palestinians. Even now, when Israel asks Gaza residents to move South, the Egyptians shut the border crossing.

Re. 4 - another point that I didn't mention (again, I didn't want to make it too long). There is a profound difference between the Hamas and the Fatah that rules the West Bank. Fatah is secular, and Hamas is a fundamentalist Islamic movement. Israel helped build Hamas to fight the Fatah, making exactly the same mistake the US did with the Taliban and the Ayatollahs. I don't know what they were thinking when they empowered a batshit crazy fundamentalist organization to fight a hostile secular regime.
