FWIW I laid out what I believe is the most realistic path for a hypothetical two-state solution, if one were to truly be attempted. My actual belief in the “real world”, is the two-state solution is dead. It’s going to be a one state solution, and I think the West Bank will eventually be annexed outright. With only the Arab population in the West Bank, Jews will still have a large demographic majority in the total country especially with the high Jewish Israeli birth rate (3/woman, actually on par with the Palestinian Arab birthrate.) Since the West Bank settlements will only continue to grow, eventually there will be a point where Israel just feels comfortable enough to annex it.
For years, one of the biggest drivers within Israel of the two state solution was the belief (based in the best demographic evidence of the time) that the one state solution would mean the eventual minority status of Jews in Israel, due to the higher birth rate of Palestinian Arabs. While the demographics in Israel and Palestine are probably the most politically charged demographics in the world, with things like exact population numbers in the West Bank and birth rate claims being made by a lot of questionable people, I do think the broad survey of evidence indicates the West Bank’s population is around 2.5m Palestinians and around 400,000 Israeli settlers and another 300,000 or so who are in the legal territory of the West Bank but not in settlements (areas in the West Bank on the Israeli side of the border wall and in East Jerusalem.)
I think there’s simply too many Israelis now in the territory, and they feel comfortable enough in their new demographic reality to just plow ahead with a one state solution (that likely will exclude Gaza.)
The Palestinians definitely got a raw deal in all this. And while I’m quick to point out I don’t remotely hold Israel blameless, I do view the largest culprit in it all the great powers for creating the untenable situation of 1947, and the Arab world for invading Israel on two occasions and creating the strategic justification for Israel’s actions. There’s a lot of power brokers in the Arab League countries that have long felt it was in their interests to use the Palestinians as pawns in a regional strategic game against Israel.
To be frank, we have started to move into a world where territorial annexations, while not common place, aren’t unprecedented nor are they punished vigorously. It’s hard to imagine at some point Israel won’t take advantage of it.
You’re also seeing changing lines of allegiance. Israel is actively cultivating better relations with both China and Russia–two countries that hold territory that isn’t legally theirs under international law, and that might have designs on eventually holding more, while they supported the most recent (toothless) resolution, given enough time for these relationships to grow I’m not sure these countries would go to the point of supporting UN backed sanctions or even more drastic actions because they themselves don’t like the idea of the international community intervening in illegal occupations.
You’re also seeing some long time Sunni Arab enemies of Israel seeing Israel as a potential ally against Iran.
I think it’s a tragedy for the Palestinians, and I think it’s a shame hard liners have taken over Israel, and that things have gone the way they’ve gone–but I think the hard realist view is there will never be two states in any meaningful sense.
