DUBAI/WASHINGTON — A 60-day window for the United States and Iran to finalize a ceasefire agreement expired Monday, with both sides unable to resolve disputes over control of the Strait of Hormuz, a critical shipping route through which one-fifth of the world’s oil supply passes. The failure to reach a deal has prompted Iran to shift from defensive to fully offensive posturing, while US President Donald Trump threatened to bomb Oman if it continues negotiating with Tehran over maritime arrangements in the strait.
Core Developments:
- Iran’s escalation threat: A senior Iranian official told Reuters that Tehran would adopt a fully offensive stance if diplomacy with the US fails, warning of timely and precise military action to break the US naval blockade. The official stated that Iran would escalate tensions in the Strait of Hormuz and wider region if the US does not honor the terms of a June memorandum of understanding (MoU) within weeks.
- US threats to Oman: Trump told Fox News on Monday that Oman would face military retaliation if it ‘gets in the way’ of US objectives in the strait. He stated, ‘If Oman gets in the way, we’ll bomb the s--- out of them.’ The president also claimed the US has direct backchannel communications with Iran’s Islamic Revolutionary Guard Corps (IRGC), a claim Tehran has denied.
Deadline Passes Without Agreement
The June 17 MoU established a 60-day framework for the US and Iran to negotiate a permanent ceasefire, including the reopening of the Strait of Hormuz. The agreement also addressed broader issues such as Iran’s nuclear program. However, disputes over control of the strait—where Iran has effectively restricted shipping since late February—halted progress. Iran asserts that point five of the MoU grants it management rights over the waterway, while the US insists it remains an international passage under US oversight.
Oman’s Role in Negotiations
Oman, a US ally and long-standing mediator in the region, has been engaged in talks with Iran to establish a joint framework for maritime navigation through the strait. Iranian and Omani officials have been discussing a joint declaration to reopen the waterway, though Trump’s threats have cast uncertainty over these efforts. Oman has historically served as a neutral facilitator, including in the 2015 Iran nuclear deal negotiations, but now faces pressure from both Washington and Tehran.
Contradictory Claims on Backchannel Talks
Trump confirmed to Fox News that the US is communicating with the IRGC, stating, ‘They’re good poker players, but they’re dying.’ However, Iran’s Foreign Ministry spokesman Esmaeil Baghaei denied any secret contacts, calling the claims ‘a fabrication intended to divide Iran’s leadership.’ The IRGC also rejected Trump’s assertion, with a spokesman telling the semi-official Tasnim News Agency that ‘there are no talks taking place between IRGC officials and the Americans.’
Regional and Global Implications
The failure to resolve the dispute risks renewed military escalation and disruptions to global oil supplies. The Strait of Hormuz, a chokepoint for 20% of the world’s oil and liquefied natural gas, has been largely closed since the US-Israel strikes in late February. Analysts warn that further instability could destabilize energy markets and trigger broader regional conflicts.
Background: The June MoU and Its Collapse
The 60-day MoU, signed on June 17, aimed to end hostilities and reopen the strait. However, disagreements over control mechanisms and sanctions relief stalled negotiations. Iran has insisted that the US must first return to the deal before the strait can reopen, while the US has framed the waterway as under its jurisdiction. The expiration of the MoU deadline has left both sides at an impasse, with no immediate plans for further talks.
Key Stakeholders and Positions
- Iran: Demands US compliance with the MoU, including sanctions relief, and asserts control over the strait. A senior official stated that ‘all provisions must be implemented by the US within weeks’ or Iran will escalate.
- United States: Insists the strait remains an international waterway under US oversight. Trump has threatened military action against Oman and called for Iran to ‘put up the white flag of surrender.’
- Oman: Pursues a neutral stance, negotiating with Iran while maintaining its alliance with the US. The country has historically mediated between Washington and Tehran but now faces conflicting pressures.
Next Steps and Risks
With no clear path forward, analysts warn of three potential outcomes:
- Renewed military confrontation if Iran proceeds with its offensive threats or the US acts on its warnings to Oman.
- Prolonged diplomatic stalemate, with continued restrictions on shipping and rising tensions.
- Third-party mediation, though no country or organization has yet stepped forward to broker a resolution.
The expiration of the MoU deadline marks a critical juncture in the US-Iran conflict, with the potential for far-reaching consequences for global energy security and regional stability.
