US–Iran Talks Edge Toward Nuclear and Hormuz Framework
Between late 23 and 24 May 2026, US and Iranian officials moved closer to a memorandum of understanding covering the Strait of Hormuz and elements of Iran’s nuclear program. American leaders stress progress but not final agreement, while President Trump publicly conditions any deal on full nuclear dismantlement.
Key Takeaways
- By the morning of 24 May 2026, multiple senior US and regional officials described significant but incomplete progress toward a US–Iran understanding on the Strait of Hormuz and nuclear constraints.
- Reporting indicates a potential deal would have Iran forgo nuclear weapons, halt new enrichment and begin talks on surrendering its stockpile of highly enriched uranium, though key timelines and disposal mechanisms remain unresolved.
- Iranian sources speak of ongoing disputes over one or two clauses in a draft memorandum of understanding, delaying a final text.
- President Donald Trump told Israeli Prime Minister Benjamin Netanyahu there would be no final deal without “full nuclear dismantlement” and removal of all enriched uranium, while assuring continued US consultation with Israel.
Through the night of 23 May and into 24 May 2026, diplomatic signals from Washington, Tehran and regional capitals pointed to an emerging but fragile framework that links Iran’s nuclear program with security arrangements in and around the Strait of Hormuz. A senior US political source briefing on 24 May confirmed that the United States is updating Israel on negotiations for a memorandum of understanding concerning Hormuz, including a path toward a final agreement on outstanding points.
Publicly, U.S. Secretary of State Marco Rubio stated on the morning of 24 May that “significant progress” had been made toward an agreement with Iran, while emphasizing that it was “not final progress” and that work remained on key details. He suggested the world could receive “good news” in the coming hours related to the Strait of Hormuz and the launch of a broader diplomatic process involving Iran.
Details emerging from US media coverage indicate that a potential deal would see Iran formally commit not to pursue nuclear weapons, halt new enrichment activities, and enter negotiations to relinquish its stockpile of highly enriched uranium. The precise modalities—where and how the material would be removed or diluted, and for how long enrichment would be paused—are described as subjects for subsequent negotiation, not yet locked into the initial understanding.
From Tehran, an Iranian outlet aligned with the Islamic Revolutionary Guard Corps reported that talks remain stalled over one or two specific clauses in the draft memorandum between Iran and the United States. According to a source familiar with the negotiations, these disputes have extended the negotiations, though both sides are still actively engaged. The contested clauses likely relate to verification mechanisms, the sequencing of sanctions relief, or restrictions on Iran’s regional military activities, though these aspects have not been officially disclosed.
President Donald Trump has sought to shape the narrative and negotiating parameters. On 24 May, he publicly declared there would be “no deal without full nuclear dismantlement” by Iran and the removal of all enriched uranium as a condition for any final agreement. In a separate conversation with Israeli Prime Minister Benjamin Netanyahu, Trump reportedly updated Israel on the Hormuz talks and heard Netanyahu reaffirm Israel’s intention to maintain freedom of action against perceived threats in the region, regardless of any US–Iran accord.
This positioning reflects a delicate balancing act: the US administration is trying to secure de-escalation around the vital shipping lanes of the Strait of Hormuz and impose stricter long-term nuclear constraints on Iran, while convincing Israel and other regional partners that their security concerns and freedom of maneuver will not be compromised.
From Iran’s perspective, any agreement that meaningfully constrains enrichment and mandates transfer of enriched stockpiles will need to be offset by tangible economic and security incentives, particularly sanctions relief and implicit or explicit assurances against external attack. Domestic hardliners in Tehran may resist deep concessions without clear, irreversible benefits.
The negotiations also intersect with recent Iranian messaging on maritime security. On 24 May, the commander of Khatam al-Anbiya, Iran’s primary joint operational headquarters, stated that Supreme Leader directives regarding the management of the Strait of Hormuz would be fully implemented, adding that “there is no place for foreigners” in the new management mechanism. This rhetoric suggests Iran is seeking formal recognition of a central coordinating role in Hormuz security, potentially in partnership with select regional actors, while limiting Western naval presence.
Outlook & Way Forward
In the short term, the most likely trajectory is continued intensive diplomacy aimed at closing the remaining gaps in the memorandum of understanding. Announcements could come in phased form: first outlining de-escalation measures for Hormuz and high-level political commitments on nuclear issues, followed later by technical annexes on verification, timelines, and uranium stockpile disposition.
Risks to a successful outcome include domestic political pushback in both Washington and Tehran, disagreement over the scope and sequencing of sanctions relief, and regional destabilizing events—such as clashes involving Iranian proxies or maritime incidents—that could harden positions. President Trump’s maximalist demand for full nuclear dismantlement may reflect negotiating tactics, but if treated as an absolute condition, it could slow or derail progress.
Observers should track: any coordinated public messaging from Iran and the US on confidence-building steps in Hormuz (such as reduced military exercises, hotlines, or incident-at-sea agreements); signs of Israeli dissatisfaction or preparations for unilateral action; and domestic reactions within Iran’s political elite and security apparatus. A limited initial framework that reduces immediate maritime tensions but leaves deeper nuclear issues only partially addressed is a plausible interim outcome, with the potential to either evolve into a comprehensive deal or unravel under regional and domestic pressures.
