What happened in Rhodesia was very different from the situation in South Africa. Whites are still very influential (especially economically) in SA. Rhodesia -> Zimbabwe is maybe closer to French Algiers.
Netherlands loses control of it about the same time as US became independent and they developed mostly independently since then
Besides that Apartheid South Africa is remarkably similar to Israel (of course the race part is entirely replaced by religion/culture making assimilation into the Israeli society actually somewhat feasible).
