The world was still reeling Wednesday from President Donald Trump's stunning proposal that the U.S. "take over" war-torn Gaza, clear the rubble and economically develop the area -- after the nearly 2 million Palestinians who live there were removed to other countries.

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.
