Washington D.C. / Tehran — May 31, 2026: In a dramatic development that simultaneously offered hope and raised new questions about the durability of US-Iran diplomacy, President Donald Trump declared on Sunday that Iran has agreed to permanently forgo nuclear weapons — even as the United States sent a significantly tougher revised peace framework back to Tehran. The dual announcement encapsulates the paradox at the heart of the current negotiations: Trump is claiming victories while simultaneously hardening his demands.
Trump's Declaration: "They've Agreed"
US President Donald Trump said he had secured guarantees from Iran that it would not develop nuclear weapons, as reports emerged he had sent a tougher peace proposal back to Tehran.
"The one guarantee that I have to have is that there will be no nuclear weapons. They've agreed to that, and it was very interesting," Trump told reporters. In a separate statement, Trump put it even more plainly: "They've agreed. They will never have a nuclear weapon. They've agreed to that."
The declaration — if accurate — would represent the single most significant concession from Iran since the war began on February 28, 2026. Iran has never publicly agreed to permanently abandon its nuclear ambitions, and its position throughout decades of negotiations has been to insist on the right to civilian uranium enrichment as a sovereign prerogative.
The 15-Point Peace Plan: America's Full List of Demands
The US has sent Iran a 15-point plan and ceasefire proposal to end the war in the Middle East. The peace plan was shared with Iranian officials via Pakistan. Trump's special envoy Steve Witkoff and son-in-law Jared Kushner are reportedly seeking Tehran to agree to a monthlong ceasefire, during which the 15 points of the plan would be negotiated.
The 14 known points of the U.S. framework include:
- Iran must dismantle existing nuclear capabilities
- Iran must commit to never pursuing nuclear weapons
- No uranium enrichment on Iranian territory
- Iran must hand its enriched uranium stockpile to the IAEA
- The Natanz, Isfahan, and Fordo nuclear facilities must be dismantled
- The IAEA must be granted full access to all Iranian nuclear facilities
- Iran must permanently cease ballistic missile development
- Iran must end all support for regional proxy forces (Houthi, Hezbollah, Hamas)
- Full reopening of the Strait of Hormuz to international shipping
- Iran must clear all naval mines from the Strait within 30 days
- Iran must release all U.S. and allied nationals held in detention
- Iran must provide a full accounting of missing Americans
- Normalization of economic relations contingent on compliance
- Iran must cease all cyberattacks on U.S. critical infrastructure

Why the Proposal Is Described as "Tougher"
The New York Times and Axios reported that Trump had sent back a new framework to be considered by Iran with "tougher" terms, though it was not immediately clear what that entailed. Any tweaks to the proposal could prolong even further an agreement to formally end the Middle East war and open the Strait of Hormuz maritime route after weeks of efforts to secure a deal despite fractious rhetoric and the occasional flare-up of armed conflict.
The toughening reportedly centers on Iran's demand to retain any management role over Strait of Hormuz navigation — a condition Washington has categorically rejected — and a new insistence that Iran's proxy network relationships be formally severed as part of any comprehensive agreement, not merely paused.
Iran Pushes Back: "No Agreement Finalised"
US officials indicated Tehran may take days to respond to Trump's tougher terms on a potential peace agreement. Iran's government was quick to complicate Trump's "they've agreed" narrative. Iranian officials publicly insisted that no agreement has been finalized and reaffirmed Tehran's position that it retains sovereign rights over the Strait of Hormuz — directly contradicting the terms Washington says Iran has accepted.
The gap between Trump's public declarations and Iran's public posture is one of the defining features of the current diplomatic moment — and it raises a critical question: are Iran's verbal commitments in private negotiations the same as what its government is willing to formally sign?
Witkoff and Kushner: The Architects of the Peace Framework
The 15-point plan reflects the work of Trump's two lead Iran negotiators. The plan is believed to be based on the 15-point framework presented to the Iranian government before Israel launched its 12-day war against Iran and the U.S. bombed Iranian nuclear facilities in Operation Midnight Hammer — updated and hardened to reflect the post-war military realities on the ground. Israel was not involved in drafting the current proposal but was given advance notice by the Trump administration before discussions began.
What Comes Next: Days of Suspense Ahead
With Iran taking days to formally respond and Trump simultaneously claiming victory and escalating demands, the coming week may be the most diplomatically consequential of the entire US-Iran war. The binary outcome is stark: if Tehran accepts the 15-point framework, the resulting agreement would be the most sweeping nuclear non-proliferation deal in history — far exceeding the 2015 JCPOA in its demands. If it rejects the terms, Pentagon chief Hegseth has already made clear the U.S. military is "more than capable" of resuming strikes immediately. The world is watching — and waiting.
