Whether or not “facts on the ground” should matter, they do. They’re the unavoidable reality.
I agree with you that many settlers should be relocated. But I don’t see any reason to believe that will happen.
Hypothetically, a transport corridor, perhaps through the desert, could link Gaza and the West Bank. But that would create security liabilities for both states, especially Palestine, hindering viability.
Perhaps I’m being too cynical, but I think too much of the discussion about Israel-Palestine focuses on hypothetical shoulds rather than what is.
