The United States and Iran have begun high‑stakes, Omani‑mediated talks over Tehran’s nuclear program in Muscat, the first such encounter since Washington joined open military confrontation with the Islamic republic last year and a negotiation many regional officials say could help decide whether the Middle East slides toward a wider war. The discussions, held indirectly through Omani officials at a palace near Muscat’s international airport, come amid deep rifts over the agenda and against a backdrop of Iranian missile deployments, tanker incidents and a deadly crackdown on protests at home.
How the Oman talks are structured
Oman is once again playing the role of discreet go‑between, as it did in the secret contacts that paved the way to the 2015 nuclear deal. Omani Foreign Minister Badr al‑Busaidi is shuttling between an Iranian delegation led by Foreign Minister Abbas Araghchi and a US team headed by Middle East envoy Steve Witkoff, with senior adviser Jared Kushner also present on the American side, according to Ankara‑based Anadolu Agency.
- The indirect negotiations began late Friday morning local time at an Omani royal palace compound near Muscat’s airport.
- AP journalists saw Iranian officials arrive at the palace and later return to their hotel, while a convoy believed to be carrying US officials was seen leaving the site.
- Ahead of the talks, Omani border officials were unusually strict about cameras entering the sultanate, underlining Muscat’s desire to keep the encounter low‑profile.
Iranian state news agency IRNA reported after the first round that Tehran had submitted a “preliminary plan” to the Omani mediators, who passed it to the US side. Both sides used the opening session to outline positions and “considerations” rather than haggle over line‑by‑line text, suggesting any concrete deal is still distant.
These are the first diplomatic contacts between Washington and Tehran since the US joined Israel’s conflict with Iran in June by striking nuclear facilities inside the country, a move that ended years of purely proxy confrontation.
Competing agendas: “nuclear only” vs “all issues”
The heart of the early tension is over what the Oman talks should cover.
Tehran has insisted that discussions are strictly about its nuclear program and the sanctions it faces. Foreign Ministry spokesman Esmail Baghaei said Iran will approach Muscat “with authority and with the goal of achieving a fair, mutually acceptable and dignified resolution regarding the nuclear issue,” but will not allow broader topics onto the table.
Washington wants a much wider agenda. Secretary of State Marco Rubio told reporters this week that any meaningful agreement must address not only uranium enrichment but also:
- Iran’s ballistic missile program,
- Its support for regional proxy groups designated as terrorists by the US, and
- Its “treatment of their own people” amid a bloody crackdown on protests.
“For the talks to yield meaningful outcomes, they must encompass various aspects, including their ballistic missile range, their support for terrorist organizations throughout the region, their nuclear program, and their treatment of their own citizens,” Rubio said, adding he was “uncertain if an agreement can be reached with these individuals, but we will attempt to ascertain that.”
Regional officials told Reuters that President Donald Trump has privately set three conditions for any broader bargain: zero uranium enrichment on Iranian soil, limits on missiles and an end to Iranian support for proxies terms Iran has repeatedly rejected as violating its sovereignty.
What Iran is signaling on enrichment
Despite its public insistence on sovereignty, Iran has sent mixed, and in some ways surprising, signals about what it might accept on the nuclear front.
Iranian officials told Reuters and regional media last week that Tehran is prepared to show “flexibility on uranium enrichment”, including:
- Handing over around 400 kilograms of highly enriched uranium (HEU) built up since it walked away from JCPOA limits.
- Accepting a period of zero enrichment under a consortium arrangement, in which an international consortium would produce nuclear fuel for its reactors, as a possible long‑term solution.
At the same time, officials stress that Iran’s right to enrich is “non‑negotiable” in principle, and domestic hardliners are wary of any arrangement that looks like giving up leverage without iron‑clad sanctions relief.
Egyptian and Qatari diplomats have floated a parallel proposal, according to Al Jazeera and AP summaries:
- Iran would halt enrichment above low levels for three years,
- Export its existing stockpile of highly enriched uranium, and
- Commit not to initiate the use of ballistic missiles in any regional conflict.
Tehran has not publicly endorsed that package, but its own hints about a 400‑kilogram HEU hand‑off suggest there is at least conceptual overlap.
Missiles, proxies, and a show of force
Just hours before the talks, Iranian state television showcased one of the country’s most advanced long‑range ballistic missiles, the Khorramshahr‑4, saying it had been deployed at a vast underground Revolutionary Guard complex. The timing was widely read as a reminder that, while Iran may be flexible on enrichment, it views its missile arsenal as a red line.
Two Iranian officials told Reuters that in internal debates, the leadership sees the ballistic missile program, rather than uranium enrichment, as the bigger obstacle to any comprehensive deal. Missiles are central to Tehran’s deterrence posture and to the doctrine of its Revolutionary Guards.
Meanwhile, tensions in the Strait of Hormuz and surrounding waters remain high. US forces recently shot down an Iranian drone near the aircraft carrier USS Abraham Lincoln, and armed Iranian boats tried to stop a US‑flagged vessel in the shipping lane, sending oil prices higher on fears of escalation. Gulf Arab states, already jittery, fear that any misstep in Oman could tip the region into a conflict that drags them in.
Domestic pressure on both sides
Both governments arrive in Muscat under intense internal pressure.
In Iran, the talks come less than a month after the peak of a new wave of nationwide protests driven by hyperinflation, soaring living costs and deep anger at the clerical establishment. Human‑rights groups and insiders estimate that as many as 30,000 people were killed in a crackdown that combined an information blackout with what one European broadcaster called “unprecedented” force.
A senior adviser to Supreme Leader Ayatollah Ali Khamenei has publicly backed Araghchi’s mission, signaling the leadership’s approval but also raising the stakes: any perceived “humiliation” in Oman could be weaponized by hardliners at home.
In Washington, Trump faces an election‑season balancing act. He has promised to be tougher than Barack Obama or Joe Biden on Iran, yet also signaled that he prefers a deal to a new war so long as Tehran meets his conditions. NPR notes that within the administration, some advisers argue that if talks collapse, the president may feel compelled to authorize military action to destroy Iranian nuclear facilities, an option that US military and Gulf partners warn could spiral rapidly.
Oman’s mediation and regional stakes
For Oman, hosting the talks is both a return to form and a diplomatic risk. The Gulf sultanate has a long history of quiet mediation between rivals, including the secret US–Iran contacts that led to the 2015 nuclear deal and more recent backchannels on Yemen.
Anadolu reports that Türkiye and other regional states played a key role in nudging both sides back to the table after weeks of heightened tensions, highlighting widespread fears that continued escalation could devastate trade, energy flows and fragile economies.
The stakes extend well beyond the nuclear file:
- A failure in Muscat could embolden hardliners in Tehran to ramp up enrichment and missile tests, narrowing the window for diplomacy.
- It could also strengthen voices in Washington, Tel Aviv and some Gulf capitals pushing for pre‑emptive strikes, potentially igniting a conflict that would endanger oil shipping lanes and destabilize economies from Europe to Asia.
- Conversely, even a modest agreement, a multi‑year enrichment freeze and HEU export, for example—could cool regional tensions, stabilize oil markets and open space for parallel talks on regional security.
What to watch as talks unfold
Diplomats and analysts say several signposts will indicate whether the Muscat talks are making real headway or merely buying time.
1. Enrichment and stockpile commitments
Does Iran formally agree to cap enrichment and ship out large quantities of HEU, and on what timeline? Concrete movement on the “400‑kilogram” offer or the three‑year freeze proposed by regional mediators would be a clear sign of progress.
2. Missile language
Even if Tehran refuses direct missile limits, any pledge not to initiate missile use in regional conflicts, or to avoid testing certain ranges, would be closely scrutinized as a gesture toward de‑escalation.
3. Scope creep or breakthrough
Does Washington manage to insert language, however vague, on proxies or human rights, or does the final text stick rigidly to the nuclear file? The answer will shape how sustainable any bargain is in US domestic politics.
4. Signals from the Strait of Hormuz
A pause in drone shoot‑downs and tanker harassment, or, conversely, a fresh incident, will be read as either confidence‑building or sabotage of the diplomatic track.
As one regional official told Reuters, speaking anonymously, both sides have “expressed a willingness to revive diplomatic efforts” but remain “far apart on what a new equilibrium should look like.”
For now, Muscat’s palace rooms are one of the few places where Washington and Tehran are not trading threats, but arguments, through an Omani mediator, over uranium, missiles, and red lines. Whether that conversation can pull the region back from the brink, or simply set the stage for the next confrontation, is the question hanging over these talks, and over a Middle East once again holding its breath.
