The US president is expected to face strong opposition from Jordan's King Abdullah at the White House today after proposing to relocate Gazans to Jordan.
Jordan, a key US ally, has been forging a difficult relationship between its military and diplomatic ties and public support for the Palestinians in the country.
Those flaws, already tested by the war in Gaza, are being undermined by Trump's Gaza peace plan.
He has stepped up his calls for the relocation of Gazans to Jordan and Egypt, telling a Fox News host that they would not have the right to return - a view that would violate international law if implemented.
On Monday, he said he could cut off aid to Jordan and Egypt if they did not take in Palestinian refugees.
Some of the most vocal opponents of the relocation of Gazans to Jordan are Gazans who have already moved there.
About 45,000 people live in Gaza camp, one of several Palestinian refugee camps in the country, near the northern Jordanian city of Jerash.
Corrugated iron sheets hang over the narrow doors of shops and children walk on donkeys between the market stalls.
All the families here have roots back in Gaza: Jabalia, Rafah, Beit Hanoun. Most fled after the 1967 Arab-Israeli war in search of temporary shelter. For generations, they have been here.
“Donald Trump is an arrogant narcissist,” Maher Azazi, 60, tells me. “He has a medieval mentality, a businessman’s mentality.”
Maher left Jabalia as a child. Some of his family are still there, now sifting through the rubble of their homes to find the bodies of 18 missing relatives.
Despite the devastation there, Mr. Azazi says that Gazans today have learned from previous generations and most would “rather jump into the sea than leave.”
Those who once saw leaving the country as a temporary refuge now see it as helping Israel’s far-right nationalists seize Palestinian land.
“We Gazans have been through this before,” says Youssef, who was born in the camp. “They told us it would be temporary, and we would return to our homes. The right to return is a red line.”
“When our ancestors left, they had no weapons to fight with, like Hamas does now,” another tells me. “Now the younger generation knows exactly what happened to our ancestors, and it will never happen again. Now there is resistance.”
The Palestinians who have taken refuge in Jordan are not the only ones – a small bulwark of stability in the Middle East’s many conflicts.
