My personal favorite is the idea that by 2047 Israel will say "ya know we were being a little too rough, let's just be separate countries that use the same currency, have freedom of movement in the same land, and share the same city as a 'joint capital.' Yeah we'll completely respect your government and allow you unfettered access to the Jordan's waters despite ongoing water wars, allow your citizens to live wherever they want, and treat you as complete equals who just so happen to claim all of each other's land."
