I fully expect Israel will get the land, and the world will be an unwitting accomplice to this abhorrence.
We will all look the other way while they sing and cheer getting "their land" back. They'll populate it with US expats/settler's and sell the regeneration of the region to Saudi/UAE consortiums, turning it into a new Dubai, all the while a million people who used to live there, are now stateless, in the desert, with nothing. I'm sure an aid package or two will be signed to "help" but it'll amount to very little.
And Israel still won't be happy, they'll still have to manufacture skirmishes and threats (omg Iran, omg Hezbollah, omg Syria) to keep the money rolling in under the guise existential threat.
The history books will be rewritten and the "peace" will be credited to their "brave" decision of taking back Palestine and liberating it from the evil clutches of Hamas.
Bleak, bleak, bleak.
