Alessan doesn’t want to annex the West Bank, so you’re probably arguing with the wrong person.
And of course, the problem with annexing the West Bank is that you’d either have to expel all the Palestinians, or allow them to stay but without civil rights, or make them citizens. Expelling them is gonna be a bit tough and would lead to regional war. Making them non-citizens gives you the status quo, so what’s the point? And making them citizens means that Israel isn’t a majority Jewish country anymore.
So either Israel has to abandon the West Bank, or abandon its majority Jewish identity, or abandon democracy. If I were an Israeli I know which option I’d choose.
