it’s worse than South Africa, Apartheid pales in comparison to what’s happening in Palestine, Palestine is the equivalent of an open air concentration camp

Fully agree this is far more extreme than South Africa, plus South Africa was <15% white, while a one state Palestine would be around 50% Jewish (and far more Palestinians than Israelis are under 18). Imo, the ideal coexistence would be administered by an eastern/global southern power, but however it's brought about, you'd need to abolish the current fascist "law of return" and give the Palestinian diaspora (over 6 million people, mostly in Jordan and Syria) right of return, reparations, etc.

Obviously deport all first generation settlers (>20% of Israel's current population) back to America and Europe, but it gets more complicated for a lot of people born there, and wouldn't really solve much imo. For one, roughly half or more of Israeli Jews are Arab Jews/Mizrahi (which would surprise some people seeing how white their government is). This is largely because, 1) intermarriage between Ashkenazis and Mizrahis has become common (if one of your parents are Ashkenazi and another Mizrahi, you're just considered Mizrahi), and 2) immigration, coercion, and kidnapping of Arab Jews from other countries was a big thing.

Mizrahis are indigenous to the Middle East, but they've essentially had their culture stolen and been forcibly assimilated. So "deporting all settlers" wouldn't solve much and would be pretty complicated to define. While Mizrahis aren't settlers, they've been indoctrinated their entire lives in the same way Ashkenazi Israelis are, and even attempt to prove themselves to the settlers by being even more fascist in a lot of cases. So unfortunately, any resistance and violence from settlers would be equally if not more likely from indigenous Mizrahis either way.

As sick and fascist as the Zionist entity is, I don't think South Africa style reintegration is a pipe dream. You have a lot of examples in history of this, look at reconciliation after the Rwandan genocide for one.
