Trump’s comments, which Time said were made by telephone on Oct 15, were published as both vice president JD Vance and secretary of state Marco Rubio warned against any annexation.

“It won’t happen. It won’t happen because I gave my word to the Arab countries. And you can’t do that now. We’ve had great Arab support,” Trump said when asked what the consequences would be for Israel if it did so.

“Israel would lose all of its support from the US if that happened.”

Trump also told Time that he believed Saudi Arabia would join the Abraham Accords, which normalise relations between Israel and Arab states, by the end of the year.

“Yes, I do. I do,” he said when asked if he thought Riyadh would join in that timeframe.

“See, they had a problem. They had a Gaza problem and they had an Iran problem. Now they don’t have those two problems,” he said, referring to Israel’s war in Gaza and Iran’s nuclear programme, which US airstrikes targeted earlier this year.

Trump then said that he would be “making a decision” on whether Israel should release high-profile Palestinian prisoner Marwan Barghouti as part of peace moves.

Barghouti – from Hamas’s rival, the Fatah movement – was among the Palestinian prisoners Hamas wanted to see released as part of the Gaza deal, according to Egyptian state-linked media.

Trump has dispatched a stream of top officials to Israel in recent days to shore up the fragile Gaza ceasefire he brokered earlier this month.

But as Vance wrapped up his three-day visit and Rubio arrived, Israeli lawmakers advanced two bills paving the way for West Bank annexation.

Vance said it was a “very stupid political stunt, and I personally take some insult to it.”

As Rubio left Washington, he warned Israel against annexing the West Bank, saying steps taken by parliament and settler violence threatened the Gaza truce.
