President Donald Trump said Monday that any agreement with Iran to end the war would require Muslim countries joining the Abraham Accords and normalizing ties with Israel.

Writing on Truth Social, Trump said negotiations with Iran were “proceeding nicely,” but warned that without a deal it would mean “Back to the Battlefront and shooting, but bigger and stronger than ever before.”

Trump said he told leaders of Muslim and Arab countries that after US efforts to “pull this very complex puzzle together,” it “should be mandatory” for countries involved to join the Abraham Accords.

He named Saudi Arabia, Qatar, Pakistan, Turkey, Egypt, and Jordan as countries he wants included. Egypt and Jordan already have longstanding peace agreements with Israel, while Turkey has maintained fluctuating ties with the Jewish state for decades.

Trump added that the process “should start with the immediate signing by Saudi Arabia and Qatar, and everybody else should follow suit.” He warned that countries refusing to sign should not take part in any Iran agreement because “it shows bad intention.”

According to Axios, several Arab and Muslim leaders reportedly responded to Trump’s proposal with silence. “There was silence on the line and Trump joked and asked if they are still there,” a US official said.

Trump also claimed that “numerous” leaders said they “would be honored” to eventually see Iran itself join the accords if a deal is reached.

Saudi Arabia and Pakistan have repeatedly stated they will not normalize relations with Israel without the establishment of a Palestinian state. Qatar also has no formal ties with Israel, despite serving as a mediator during the Gaza war.

Trump called the Abraham Accords an “unparalleled World Coalition” that could make the Middle East “United, Powerful, and Economically Strong.” He said he instructed Steve Witkoff and Jared Kushner to begin efforts to expand the agreements immediately.

The push comes as Israeli officials reportedly express concern over the emerging Iran deal, warning it may not address Tehran’s nuclear program, ballistic missiles, or support for regional terrorist proxies.
