President Trump’s plan to uproot more than 2 million Palestinians from the Gaza Strip, relocate them to neighboring Arab states and remake the territory as a Middle Eastern “Riviera” has already had one clear real-world impact: It has rocked Arab states and forced them to reconsider an endgame to the latest eruption of Palestinian-Israeli violence.

Trump said early this month he wants to forcibly relocate almost 2 million Palestinians from Gaza into neighboring Jordan and Egypt. He said the United States will “own” the territory and turn it into the “Riviera of the Middle East,” which prompted rejection by Arab countries.
