Iran's 10-point plan claims a right to enrichment; the US demands zero. The gap is publicly irreconcilable.

Key takeaway

Both sides published irreconcilable enrichment positions with no verification architecture to bridge the gap.

Iran tabled a 10-point plan at Islamabad listing "acceptance of enrichment" as non-negotiable. The United States tabled a 15-point plan demanding a zero nuclear weapons commitment, removal of Iran's HEU stockpile from the country, limits on defence capabilities, and unconditional Hormuz reopening. Donald Trump posted that "there will be no enrichment of Uranium" ; Iran's plan explicitly claims the right to it.

Sanam Vakil, Chatham House's Middle East and North Africa director, assessed that Iran is "unlikely" to surrender its HEU stockpile and that downblending to lower enrichment levels is the realistic floor for any deal. Iran's Foreign Minister Abbas Araghchi had publicly offered downblending on CBS in March, but Islamabad's US demands went further: full removal of the material from Iranian territory.

The last verified stockpile figure is 440.9 kg of uranium enriched to 60%, recorded by the IAEA (International Atomic Energy Agency) in September 2025, before the strikes. At 60% purity, that quantity requires relatively modest further enrichment to reach weapons-grade; the IAEA defines a "significant quantity" for a single device at 25 kg of 90%-enriched uranium. Since the Majlis voted 221-0 to suspend all IAEA cooperation on 3 April , no independent verification has been possible.

The Arms Control Association assessed in March that US negotiators were "ill-prepared for serious nuclear negotiations." The JCPOA (Joint Comprehensive Plan of Action) took 20 months of structured talks with continuous IAEA access to bridge a comparable enrichment gap. Islamabad attempted the same in two days, without inspectors.

Deep Analysis

In plain English

Enriched uranium is nuclear fuel. You enrich it a little (3-5%) and it powers a reactor. You enrich it a lot (90%+) and you can make a bomb. Iran is enriching to 60%, which is well above reactor grade and much closer to weapons grade than is comfortable. The US wants Iran to hand over this stockpile and never enrich again. Iran says that enriching uranium is its sovereign right, like any country operating nuclear power. The two positions are like arguing whether someone should be allowed to own a gun: one side says no guns at all, the other says guns are a constitutional right. The extra complication is that the international inspectors who would verify any deal, the IAEA, have been banned from Iran since early April. So even if both sides agreed on something, there is currently no one to check whether Iran is doing what it promised.

Deep Analysis
Root Causes

Iran's enrichment programme is not purely a weapons issue, it is tied to domestic electricity generation ambitions and to a sovereignty narrative built over 20 years of sanctions. Accepting zero enrichment would require Iran's leadership to abandon a national project that predates the current conflict by decades.

The IAEA monitoring blackout since the Majlis vote of 3 April means any enrichment concession Iran makes cannot be verified by a neutral third party. Without verified downblending, the US cannot make a political case domestically that a deal has worked. The monitoring gap is therefore a prerequisite problem, not a technical footnote.

The post-strike status of the 440.9 kg stockpile is unknown. If strikes have degraded or destroyed some portion of it, Iran may be offering to 'downblend' material it no longer holds in its pre-strike form, a concession with less strategic cost than it appears.

What could happen next?
  • Risk

    The Majlis 221-0 vote suspending IAEA cooperation means any nuclear concession Iran makes cannot be verified, removing the technical foundation for a deal that would satisfy US domestic and Congressional scrutiny.

    Immediate · High
  • Consequence

    Iran's public 10-point plan listing enrichment as non-negotiable has created a domestic accountability problem: any Iranian delegation that walks back enrichment rights now faces parliamentary backlash, shrinking the negotiating space even if leadership privately wanted to move.

    Short term · High
  • Opportunity

    Araghchi's March downblending offer and the Oman FM's 'irreversible fuel conversion' claim suggest a middle position exists if both sides can find face-saving language, a JCPOA-style 'limited enrichment under monitoring' framework could provide that cover.

Causes and effects
Caused by
Enrichment Gap Hardens Before Talks Open
Trump's public enrichment position (ID:2145) and Iran's 10-point plan tabled at Islamabad are directly contradictory, making the gap publicly irreconcilable.

IAEA goes dark, OFAC skips Iran file
IAEA monitoring going structurally dark (ID:2210) means the 440.9 kg HEU stockpile figure cited at Islamabad cannot be independently verified, undermining the nuclear negotiating baseline.

This Event
Enrichment gap blocks any nuclear text
The enrichment deadlock is not a negotiating position that can be split; both sides have staked public credibility on mutually exclusive outcomes, and IAEA monitoring is dark.
Led to
Iran admits enrichment capacity is destroyed
Incompatible enrichment proposals at Islamabad led Araghchi to publicly disclose that Iran cannot enrich — undermining the stated US demand.

Different Perspectives

Islamabad (Pakistan Armed Forces and Foreign Ministry)
Munir's cancellation reflects Islamabad's assessment that no bridging formula survives the collision of Khamenei's uranium directive, Rubio's Hormuz red line, and the sequencing gap simultaneously; Naqvi's relay role signals continued Pakistani engagement without a mandate to close any of the three gaps.

Published PGSA coordinates give underwriters the cartographic input to model tanker route exposure inside the claimed zone; OFAC's Sunday GL V ruling determines whether Hengli-Singapore dollar-clearing routes carry secondary-sanctions risk from Monday, adding a compliance layer to the existing kinetic war-risk premium.

Zaleh's trial lasted 'only a few minutes' before a conviction on PDKI membership charges at Naqadeh; the pattern of solitary detention, coerced confession, and minutes-long hearing is consistent with wartime political-charge architecture the organisation has documented across the Kurdish northwest.

The UAE has not published counter-coordinates to the PGSA's Hormuz zone map, leaving Emirati silence as the maritime-law response to Iran's charted boundary claim. Abu Dhabi's published position now defaults by omission toward implied acceptance of the zone's cartographic fact.

MOFCOM's blocking order covers Hengli and four other designated refineries on the mainland but does not extend to the dollar-clearing layer in Singapore, making Sunday's GL V expiry the first live test of whether Beijing's sanctions-defiance architecture reaches the place where dollars settle.

Trump's verbal track on Iran has produced no signed Iran-specific presidential instrument across 84 days; both financial-sector EOs signed on 19 May are unrelated to Hormuz or the IRGC. Rubio's public naming of the Hormuz toll architecture as a deal-killer is the administration's most concrete new position this week.
