Iran's foreign minister disclosed that the country can no longer enrich uranium at any facility, meaning Islamabad's two-day deadlock over enrichment rights was partly a dispute over a capability Iran does not possess.

Key takeaway

Both sides at Islamabad negotiated over a capability Iran cannot currently exercise.

Abbas Araghchi, Iran's Foreign Minister, confirmed on Sunday that Iran "is no longer enriching uranium at any site in the country due to the strikes" ¹. The US and Israeli campaign destroyed Natanz, damaged Esfahan, and struck Fordow. Iran's last verified stockpile, 440.9 kg of Weapons-Grade Uranium (at near weapons-grade purity), was recorded by the IAEA (International Atomic Energy Agency) in September 2025, before the war. That stockpile cannot grow without functioning centrifuges.

The IAEA has had no access since the Majlis (parliament) voted 221-0 to suspend all cooperation in early April . What both sides argued over in Islamabad, neither side can verify. JD Vance presented what he called a "final and best offer" at Islamabad before departing on Saturday with no agreement . Three structural deadlocks blocked the text: Iran's refusal to forswear weapons, its refusal to surrender its stockpile, and its demand for Hormuz toll-collection authority .

Araghchi described the talks as "the most intensive engagement between the two countries in 47 years" and claimed discussions reached "the brink of a potential memorandum of understanding." Vance called the breakdown "bad news for Iran much more than for the US." The two accounts cannot both be accurate. Neither can be independently verified.

Deep Analysis

In plain English

Iran has been enriching uranium , the process of concentrating a specific form of uranium , for years. This matters because highly enriched uranium is the primary material needed to build a nuclear weapon. The US and Israel bombed Iran's enrichment facilities in the war. Iran's Foreign Minister now says the bombing worked: Iran cannot currently enrich uranium at any facility because all of them were damaged or destroyed. Here is the strange part: at the Islamabad peace talks, the main disagreement was over whether Iran would agree to stop enriching uranium. But both sides were apparently negotiating over something Iran cannot currently do anyway. The real dispute is about whether Iran should have the right to start enriching again once it rebuilds , which is a political question, not a technical one.

Deep Analysis

Root Causes

The enrichment deadlock at Islamabad was partly a dispute over a capability Iran cannot currently exercise, and partly a dispute over the right to exercise it in future. The structural root cause is the gap between Tehran's declared position (enrichment is a sovereign right enshrined in the NPT's Article IV) and Washington's demand (zero enrichment commitment).

Araghchi's admission does not resolve that structural gap. Even a country with zero current enrichment capability can insist on the right to resume enrichment, and Iran's 10-point plan explicitly includes enrichment rights as non-negotiable. The deadlock is therefore political, not technical , which is why Araghchi's disclosure, rather than resolving the Islamabad breakdown, merely makes the political nature of it transparent.

What could happen next?

Consequence
The US demand for 'zero enrichment commitment' is no longer about stopping active enrichment , it is about preventing future reconstruction. This shifts the negotiating frame from arms control to political submission, making a deal structurally harder.
Short term · 0.82
Meaning
Araghchi's framing of talks as 'the most intensive engagement in 47 years' and 'on the brink of an MOU' is Tehran's diplomatic record-setting , establishing a narrative that the US walked away from a near-deal, not that Iran refused.
Immediate · 0.78
Risk
With IAEA access suspended, there is no mechanism to verify whether the 440.9 kg HEU stockpile has been moved, dispersed, or partially weaponised , meaning the enrichment pause provides no verifiable security benefit without inspection access.

Primary parallel: Iraq's admission in 1991 that it had no weapons of mass destruction was structurally accurate but diplomatically irrelevant: the international community required verification, not assertion.

The IAEA's current position mirrors the post-Gulf War UNSCOM model , no access, no verification, no certainty. Iran's Majlis suspended all IAEA cooperation on 3 April , meaning Araghchi's claim about enrichment capability is unverifiable by the only body with standing to verify it.

Counter-parallel: Libya's 2003 voluntary nuclear programme disclosure worked precisely because Gaddafi allowed full IAEA access within weeks of the announcement. Iran has done the opposite: asserted a capability constraint while simultaneously expelling the inspectors who could confirm it. The structural conditions for the Libya parallel do not exist.

Consensus view: The Vienna-based Arms Control Association and the Middlebury Institute of International Studies (Jeffrey Lewis) assess Araghchi's admission as technically plausible: Natanz's underground halls housed roughly 5,000 centrifuges and were the primary enrichment site.

Fordow's mountain depth protected it structurally, but the GBU-72 Advanced 5K Penetrator deployed in the campaign (ID: Fordow entity context) may have rendered the facility operationally inert without destroying it physically , severing power, ventilation, and cascade connections. The 440.9 kg HEU stockpile cannot grow in a facility with no functional centrifuge cascade.

Counter-view: The Foundation for Defence of Democracies (FDD) and Israeli intelligence assessments reviewed by Haaretz caution that 'cannot enrich' from Araghchi's civilian diplomatic apparatus does not mean the IRGC's dispersed reserve capacity is fully accounted for.

Iran's nuclear programme has operated under a dual-track architecture since at least 2010: the declared IAEA-monitored sites, and an undeclared capacity assessed by Israeli intelligence to include mobile enrichment capability. Araghchi speaks for the civilian Foreign Ministry, not the IRGC's Amad Plan successors.

Key tension: Whether Araghchi's admission reflects the actual state of all enrichment capacity , declared and undeclared , or only the civilian government's knowledge of declared sites that the IRGC may have already evacuated or replicated elsewhere.

Different Perspectives

Shipping and insurance industry

UKMTO counted about 20 US-facilitated Hormuz transits a day to 11 September against only 6 visible on AIS, with traffic still around 90% below the 138-a-day pre-war baseline. War-risk underwriters cannot price hulls they cannot see, or resolve whether the tanker El Gaia hit a mine, as Iran claims, or a missile and drone, as CENTCOM says.

European refiners

European refiners, including Poland's Orlen, absorbed a roughly $26 gap between Dated Brent at $130.80 on 15 September and ICE Brent futures settling at $103.87 on 18 September, a spread that widened from $13.45 on 9 September rather than newly opening. Their futures hedges no longer cover what they now pay for physical barrels.

Saudi Arabia

Saudi Aramco zeroed European term customers' October allocations and rerouted roughly 60 million barrels to Asia through Ras Tanura and Sohar, using Red Sea and Gulf terminal capacity built years ago to cut Hormuz exposure. Riyadh reallocated existing supply rather than negotiating a shortfall with Europe.

Qatar

Qatar's energy minister Saad al-Kaabi told Bloomberg at the Qatar Economic Forum on 20 September that Bessent's two-year Hormuz-obsolescence forecast is wrong, and that Doha has deliberately built no bypass pipeline. Qatar's gas exports run through one waterway by choice, not oversight.

Iran (foreign ministry and Majlis)

Iran's foreign ministry and 130 Majlis deputies moved toward NPT withdrawal this week, with lawmaker Hossein-Ali Haji Deligani filing a triple-urgency bill on 20 September that Speaker Qalibaf has not yet scheduled. Tehran treats treaty membership as leverage still on the table, not yet spent.

Russia and China

Moscow and Beijing vetoed the Panel of Experts' renewal, maintaining Resolution 2231 lapsed in October 2025 and the 2025 snapback was never validly triggered, so the sanctions architecture the Panel enforces has no current legal standing. Both governments frame the veto as upholding law, not shielding Tehran.
