President Donald Trump's plan for the United States to take over Gaza, permanently displacing Palestinians who live there and creating the "Riviera of the Middle East," has upset Arab nations and Western allies and would overturn decades of American policy in the region.

Experts say a proposal to move all Palestinians out of Gaza and remake it as a U.S. territory would be time-consuming, extraordinarily costly and probably a violation of international law.

Mad” is how one Middle East source reacted to US President Donald Trump’s announcement of a “takeover” of Gaza. So why would someone well versed in Trumpian tactics and the nuance of Middle East diplomacy give such an undiplomatic assessment?
