I still think a 3-state solution is the only viable one, but I could never see anyone convincing Egypt to take Gaza. Jordan taking the West Bank, maybe.
No one wants a 3-state solution except Americans who know nothing about Arabs.
I'm very aware: I said most viable, not most popular.
Similarly, I'd say that even though very few people claim to "want" large territory transfers between Israel and Palestine, I think that would have to be an integral part of any viable two-state solution.
Which is exactly why the two-state solution is not viable, especially as long on one side gets to decide unilaterally what gets transferred.
Why do you think making Palestine take the Arab triangle would make the two state solution non-viable?
