Though heavily dependent on US aid, Amman and Cairo face political calamity at home should they comply

• Middle East crisis – live updates

International outrage in recent days has focused on Donald Trump’s proposal that the US take “ownership” of Gaza, and that more than two million Palestinians be displaced to allow the territory to be transformed from “a demolition site” into a “riviera” in the Middle East.

In Jordan and Egypt, the demand that both countries accept huge numbers of Palestinians from Gaza – potentially on a permanent basis – has prompted equal concern. Leaders of both countries immediately rejected the proposal, and the Jordanian king, Abdullah II, and Abdel Fatah al-Sisi, the Egyptian president, are heading for Washington in an attempt to convince Trump to change course.
