WASHINGTON — President Donald Trump on Tuesday suggested that displaced Palestinians in Gaza be permanently resettled outside the war-torn territory and proposed the U.S. take “ownership” in redeveloping the area into “the Riviera of the Middle East”

Trump’s brazen proposal appears certain to roil the next stage of talks meant to extend the tenuous ceasefire between Israel and Hamas and secure the release of the remaining hostages held in Gaza.

The provocative comments came as talks are ramping up this week with the promise of surging humanitarian aid and reconstruction supplies to help the people of Gaza recover after more than 15 months of devastating conflict. Now Trump wants to push roughly 1.8 million people to leave the land they have called home and claim it for the U.S., perhaps with American troops.

“The U.S. will take over the Gaza Strip, and we will do a job with it too,” Trump said at an evening news conference with Netanyahu by his side. The president who made his name as New York real estate developer added: “We’ll make sure that it’s done world class. It’ll be wonderful for the people — Palestinians, Palestinians mostly, we’re talking about.”

Trump outlined his thinking as he held talks with Israeli Prime Minister Benjamin Netanyahu at the White House, where the two leaders also discussed the fragile ceasefire and hostage deal in the Israeli-Hamas conflict and shared concerns about Iran.

Trump said the U.S. would redevelop the territory after Palestinians are resettled elsewhere and turn the territory into a place where the “world’s people”— including Palestinians — would live. He offered no detail about what authority the U.S. would use to take the land and develop it.

Egypt, Jordan and other U.S. allies in the Mideast have cautioned Trump that relocating Palestinians from Gaza would threaten Mideast stability, risk expanding the conflict and undermine a decades-long push by the U.S. and allies for a two-state solution.

Saudi Arabia’s foreign ministry issued a sharply worded reaction to Trump, noting their long call for an independent Palestinian state was a “firm, steadfast and unwavering position.”

“The duty of the international community today is to work to alleviate the severe human suffering endured by the Palestinian people, who will remain committed to their land and will not budge from it,” the Saudi statement said.

Still, Trump insists the Palestinians “have no alternative” but to leave the “big pile of rubble” that is Gaza. He spoke out as his top aides stressed that a three-to-five-year timeline for reconstruction of the war-torn territory, as laid out in a temporary truce agreement, is not viable.

Last week, both Egyptian President Abdel Fattah el-Sissi and Jordanian King Abdullah II dismissed Trump’s calls to resettle Gazans.

But Trump said he believes Egypt and Jordan — as well as other countries, which he did not name — will ultimately agree to take in Palestinians.

“You look over the decades, it’s all death in Gaza,” Trump said. “This has been happening for years. It’s all death. If we can get a beautiful area to resettle people, permanently, in nice homes where they can be happy and not be shot and not be killed and not be knifed to death like what’s happening in Gaza.”

Trump also said he isn’t ruling out deploying U.S. troops to support reconstruction of Gaza. He envisions “long-term” U.S. ownership of a redevelopment of the territory.

The president’s proposal was greeted with alarm by Democrats and a measure of skepticism by his Republican allies.

“He’s completely lost it,” said Sen. Chris Murphy, D-Conn. “He wants a U.S. invasion of Gaza, which would cost thousands of American lives and set the Middle East on fire for 20 years? It’s sick.”

“We’ll see what our Arab friends say about that,” said Sen. Lindsey Graham, a South Carolina Republican and a Trump ally.

“And I think most South Carolinians are probably not excited about sending Americans to take over Gaza. I think that might be problematic, but I’ll keep an open mind.”
