President Donald Trump said Monday that he has demanded that the leaders of six Muslim countries must join the Abraham Accords if they want to be part of the deal that is currently being negotiated with Iran, which Trump said is “proceeding nicely!”

Trump stated that demand in a Memorial Day post on Truth Social. He said that during a Saturday phone call, he told the leaders of Saudi Arabia, Qatar, Egypt, Pakistan, Turkey, and Jordan that he wants them all to normalize relations with Israel by agreeing to the 2020 Abraham Accords, which were brokered by the U.S. during Trump’s first term as president. 

“I stated that, after all the work done by the United States to try and pull this very complex puzzle together, it should be mandatory that all of these Countries, at a minimum, simultaneously, sign onto the Abraham Accords,” the post reads.

The first two nations that signed on to the accords in September 2020 were the UAE and Bahrain, with Morocco and Sudan following in December and January, according to the New York Post. 

“It may be possible that one or two have a reason for not doing so, and that will be accepted, but most should be ready, willing, and able to make this Settlement with Iran a far more Historic Event than it would, otherwise, be,” added Trump. He said he is “mandatorily requesting” the concession from those nations.

“If they don’t, they should not be part of this Deal in that it shows bad intention.”
