U.S. President Donald Trump said Monday that negotiations with Iran are “proceeding nicely,” but insisted that any final agreement should be tied to a wider expansion of the Abraham Accords, calling for multiple additional countries to join the U.S.-brokered normalization framework.

Axar.az reports, in a post on Truth Social, Donald Trump said he told several Middle Eastern leaders during recent discussions that participation in the accords should be “mandatory” alongside any Iran settlement.

He added that Saudi Arabia, Qatar, Pakistan, Turkiye, Egypt, Jordan, and Bahrain are countries that should formally join the agreements, while noting that Bahrain and others are already signatories. He also said “one or two” countries might be exempted, but argued most should participate.

"It should be mandatory that all of these Countries, at a minimum, simultaneously sign onto the Abraham Accords," he wrote.

Trump framed the expanded accords as central to what he called a “historic” regional settlement, saying Iran itself could eventually be included if a deal is reached.

"Most (countries) should be ready, willing, and able to make this Settlement with Iran a far more Historic Event than it would otherwise be," he added.

He also warned that failure to reach an agreement could result in a return to heightened conflict, while emphasizing that “nobody wants that.”

The Abraham Accords, first signed in 2020 during Trump’s presidency, established diplomatic normalization between Israel and several Arab and Muslim-majority states, and have since been expanded to include additional countries.
