Israel’s defense minister says he has instructed the army to prepare plans for large numbers of Palestinians to leave the Gaza Strip in line with President Donald Trump’s proposal for the war-ravaged territory.

Trump has repeatedly mentioned the possibility of Jordan and Egypt opening their borders to allow for the mass evacuation of Palestinians out of Gaza over concerns that the area is uninhabitable.

Speaking of the two Israeli neighbors, Aaron David Miller, a former US Middle East peace negotiator, said on CNN: “It’s not a real estate deal for them, it’s not even a humanitarian issue for them. It’s an existential issue.”
