Tehran has made a substantial diplomatic concession aimed at breaking the deadlock in the eight week old war. According to a senior Iranian official who spoke to Reuters on condition of anonymity, the Islamic Republic has formally proposed to Washington through Pakistani mediators a phased plan to end the hostilities. Under the framework, Iran would immediately reopen the strategic Strait of Hormuz to international shipping, and the United States in turn would lift its naval blockade of Iranian ports. Crucially, the proposal would postpone negotiations over Iran’s nuclear programme to a later stage, allowing the most contentious issue to be addressed only after a durable ceasefire has been established and the immediate humanitarian and economic crisis has been resolved.
The official emphasised that this represents a major shift in Tehran’s posture. “Under this framework, negotiations over the more complicated nuclear issue have been moved to the final stage to create a more conducive atmosphere,” the official said. Iran would also seek a formal guarantee that neither the United States nor Israel would launch further attacks, while Tehran would similarly commit to no future strikes. In return for these mutual non‑aggression pledges, future talks would then be held on curbs to the nuclear programme in exchange for the lifting of economic sanctions, with Iran demanding that Washington recognise its right to enrich uranium for peaceful purposes, even if it agrees to a temporary suspension.
This package was formally conveyed to the United States through Pakistan, and its receipt has already registered in global energy markets: on 1 May, oil prices fell sharply after Iranian media confirmed that Tehran had submitted a fresh proposal to mediators, raising hopes of an easing in tensions. West Texas Intermediate briefly dipped below $100 a barrel, while Brent crude also retreated.
Despite these steps, President Donald Trump has rejected the offer. Speaking to reporters on Friday, he said he was “not satisfied” with what Tehran was seeking, adding: “They’re asking for things that I can’t agree to.” In a subsequent phone interview with Axios, Trump stressed that the United States would not lift its blockade until a comprehensive nuclear deal is reached, complaining that Iran was “choking like a stuffed pig.”
The president’s criticisms, however, have remained notably vague. He has offered no detailed explanation of precisely which elements he finds objectionable, raising questions about whether the rejection is driven more by domestic political considerations, such as pressure from allies like Israel than by a careful assessment of the proposal’s merits. It is also striking that the White House has not ruled out further diplomacy; Trump himself acknowledged that talks have continued “over the phone” in recent days. This suggests that even the administration recognises that the Iranian proposal is a workable foundation for negotiation, even if it is reluctant to publicly admit it.
At the heart of the impasse is a fundamental disagreement over sequencing. Washington has consistently insisted that any deal to end the war must include upfront guarantees that Iran will never develop a nuclear weapon, including strict limits on uranium enrichment. Yet Iran has consistently maintained that its nuclear programme is entirely peaceful and conducted under the supervision of the International Atomic Energy Agency. By proposing to postpone nuclear talks to a final stage, Tehran has demonstrated genuine flexibility, moving away from its earlier demand that the blockade be lifted before any discussions could begin.
It is also worth noting that the timeline for a potential deal has already been affected by events in the Middle East. The war, which began with joint US-Israeli strikes on 28 February, has claimed thousands of lives, mostly in Iran and Lebanon, and has created the most severe disruption to global energy supplies in history. The closure of the strait has choked off approximately 20 percent of the world’s oil and gas, pushing prices up by nearly 50 percent since the conflict began and fuelling inflation across the globe.
Iran has left the door open for further diplomacy. Foreign Minister Abbas Araghchi has said that Tehran is ready for a genuine negotiation if the United States changes its approach, and Iranian officials have indicated that they remain willing to engage through the Pakistani channel. The proposal has also been made public through multiple media outlets, suggesting that Tehran is seeking to rally international support for its position and to demonstrate that it is the United States, not Iran, that is blocking a deal.
Analysts have pointed out that the proposal could be seen as a “win‑win” for both sides. For Washington, it would immediately relieve upward pressure on global oil prices, easing voter anxiety ahead of the November midterm elections. For Tehran, it would bring an end to an economically damaging war and open the way for sanctions relief. Yet Trump’s insistence on tackling the nuclear issue first, an issue that has defied resolution for more than a decade, risks prolonging a conflict that is already costing the US an estimated $25 billion and is causing mounting political difficulties for the president at home.
