Pakistan’s army chief visited Tehran this week as US Secretary of State Marco Rubio reported “slight progress” in nuclear talks, while Qatar mediators rushed to Tehran as negotiations on reopening the Strait of Hormuz reached what participants described as a “climax”. The proposed framework, according to reporting by The Guardian, involves a memorandum of understanding on the strait that would be followed by thirty days of nuclear talks — crucially, deferring the US demand that Iran hand over its stockpile of highly enriched uranium immediately. Iran has, in recent days, both threatened to impose tolls on commercial shipping through Hormuz and indicated willingness to negotiate those same terms away. Rubio, who has simultaneously described the July NATO summit in Ankara as “one of the more important leaders’ summits in the history of NATO”, confirmed that US allies refused to join Iran operations and that this will need to be addressed collectively. NPR reported that the Trump-Xi summit readout contained “minor inconsistencies” on how both sides characterised the agricultural and rare earths components — a footnote that, in context, matters.
The received wisdom
The diplomatic case for pursuing these talks is, on its face, strong. The alternative to negotiated de-escalation is a shooting war in the world’s most important oil chokepoint. Approximately 20% of global oil supply and 25% of global liquefied natural gas passes through the Strait of Hormuz. A genuine closure, even partial, would spike energy prices globally, hitting developing economies hardest. Iran is a rational actor in the instrumental sense — it responds to pressure and incentive. The fact that Rubio reports slight progress after weeks of escalation suggests that the coercive element of US policy is working as intended: bringing Tehran to the table. The thirty-day deferral on the uranium question is not a capitulation; it is the normal sequencing of complex arms-control negotiations, in which confidence-building measures precede the hardest asks. Qatar, which maintains formal diplomatic relations with both the US and Iran and hosts the largest US airbase in the region, is a sensible intermediary. Pakistan’s involvement reflects a desire by Tehran to show it has regional backing. None of this is surprising, and the received wisdom says: let the diplomats work.
The multilateral dimension carries genuine weight. If European allies and Gulf partners can be brought into a framework — even a partial one — the result is more durable than a bilateral US-Iran deal, which historically collapses on presidential change.
A different read
The pattern that most concerns a historically minded observer is not whether the current talks will produce an agreement — they may well — but what the agreement will actually contain and whether its implementation will hold.
The 2015 Joint Comprehensive Plan of Action (JCPOA) was, by most technical assessments, working as a nuclear non-proliferation instrument: Iran’s stockpile of low-enriched uranium had been drastically reduced, centrifuge counts were limited, and the IAEA’s inspection regime was functioning. The Trump administration’s 2018 withdrawal was, on those purely technical grounds, a setback. But the JCPOA’s critics — including a non-trivial number of serious non-proliferation experts, not merely hawkish politicians — pointed to an architecture problem: the agreement addressed enrichment quantities but not enrichment capacity in a permanent way, it sunset key restrictions within fifteen years, and it was explicitly not linked to Iran’s ballistic missile programme or its network of proxy militias across Lebanon, Syria, Iraq, and Yemen. The deal was a partial solution dressed as a comprehensive one.
What is being negotiated now, under the framework Rubio is describing, is not obviously more comprehensive. The thirty-day deferral on uranium hand-over is presented as sequencing. But Iran’s stockpile of highly enriched uranium is now, per IAEA estimates cited in Guardian reporting, substantially larger than it was at the JCPOA’s conclusion — enriched to 60%, one technical step from weapons-grade. Iran gained that stockpile during the period when it was nominally in talks with Europe, Russia, and China about rejoining the JCPOA. The lesson that Tehran’s negotiators appear to have internalised is that talks themselves provide diplomatic cover for continued technical advancement. Deferring the uranium question to a thirty-day window, without advance verifiable action, risks repeating that pattern.
The “slight progress” language from Rubio is worth parsing. In diplomatic vocabulary, “slight progress” is distinguishable from “no progress” and from “significant progress.” It is the kind of language that keeps talks alive while managing expectations — the language of a process that officials believe is useful to continue but cannot yet defend as consequential. The “minor inconsistencies” between the US and Chinese readouts of the Trump-Xi summit on agricultural and rare earth agreements are a parallel signal: the transactional underpinning of a potential Iran deal — Chinese cooperation on Iranian oil sanctions, American flexibility on Taiwan arms — is itself in an ambiguous state.
The energy markets will not wait for diplomatic sequencing to resolve. Gulf economies are already facing long-term hits from the conflict, per BBC Business reporting. The UAE’s calculation that a functioning Hormuz is worth a significant diplomatic price is what is actually driving the Qatar mediation. Whether the US can hold its own position — demanding uranium removal — while simultaneously seeking Gulf investment and Chinese cooperation is the central tension. History suggests these tensions do not resolve cleanly.
What to watch
The thirty-day nuclear talks, if the MOU holds, are the primary watch item: what Iran agrees to on uranium enrichment, what the inspection regime looks like, and whether Russia and China sign on to any verification framework. An agreement without Russian and Chinese enforcement buy-in is structurally similar to the post-JCPOA frameworks that failed.
Watch the oil price. If Brent crude falls substantially on news of an MOU, the market is assigning real probability to a Hormuz reopening — which will then create political pressure to conclude talks rather than pursuing maximum demands. Watch also whether Taiwan’s arms pause continues: The Guardian reported that the $14 billion weapons package was paused to preserve munitions for Iran operations. If that pause extends past the MOU phase, it will be a signal that the administration is trading Taiwan security for Iran de-escalation — a trade that will not be acknowledged openly but will be noticed in Taipei.
