Trump says Iran has US nuclear proposal, must act quickly

US President Donald Trump said on Friday that Iran has received a formal American proposal for a nuclear agreement and warned Tehran to respond swiftly or face consequences.

“They have a proposal. More importantly, they know they have to move quickly or something bad—something bad's going to happen,” Trump told reporters aboard Air Force One after leaving the United Arab Emirates.

Axios reported Thursday that the written proposal was delivered during the fourth round of indirect talks between US and Iranian officials last Sunday in Muscat, Oman. It was the first formal offer made by the Trump administration since negotiations began in April, Axios cited US and diplomatic sources saying.

The document, handed over by White House envoy Steve Witkoff, outlines terms for a civilian nuclear program, with specific provisions for international monitoring and verification.

Iranian Foreign Minister Abbas Araghchi reportedly took the proposal back to Tehran for review by Supreme Leader Ali Khamenei, President Masoud Pezeshkian, and other senior officials.

Witkoff described the proposal as “elegant” and “very big” in a recent briefing to the United Nations Security Council, according to Axios, but acknowledged that more work was needed. A fifth round of talks has not yet been scheduled.

Iran has responded positively in public statements. Ali Shamkhani, a senior adviser to Khamenei told NBC News that Tehran is ready to stop enriching uranium to weapons-grade levels, reduce its stockpiles and accept inspections—if the United States lifts all sanctions.

US Secretary of State Marco Rubio, speaking Thursday from Turkey, said the diplomatic window remains open but warned the decision ultimately rests with Iran’s leadership.

“In the end, the decision lies in the hands of one person, and that's the Supreme Leader in Iran, and I hope he chooses the path of peace and prosperity, not a destructive path,” Rubio told reporters.
