Tehran pushes back on the 'first violator' frame as Hormuz and JCPOA disputes resurface

At 15:13 UTC on 18 July 2026, Esmaeil Baqaei, the spokesperson of Iran's Ministry of Foreign Affairs, took a familiar line of argument and sharpened it. Iran, he said, has never been the initiator of any violation of its nuclear commitments, and the United States breached both the 2015 Joint Comprehensive Plan of Action (JCPOA) and a more recent arrangement reached in Islamabad before Tehran did. The remarks, carried live by Tasnim News and summarised in identical language minutes later by The Cradle's English channel, put Tehran on the front foot in a debate that has otherwise been framed from Washington: who broke the deal, and what follows from that.

The exchange matters because it sits at the intersection of two legal tracks that Iran has spent the past year trying to keep separate. The older one is the JCPOA itself, formally abandoned by the United States in 2018 but technically still in force for Iran under a 2025 law that links any reversal to a finding of reciprocal non-compliance. The newer one is an Islamabad-track understanding, the contours of which Iranian state media have hinted at since spring but which has not been published in full. Baqaei's claim is that the second track was undermined first, and that this is the predicate for any subsequent Iranian response.

The 'first violator' frame

The diplomatic line Baqaei repeated in three separate appearances between roughly 13:58 and 15:15 UTC is built on a single legal move. By characterising Washington as the first party to deviate, Iran seeks to position any subsequent enrichment or missile activity as a defensive measure permitted under the reciprocity clauses of the original JCPOA, rather than as a new breach requiring fresh UN Security Council action. The argument is not new; it has been a fixture of Iranian statements since at least 2019, and it has aged unevenly. European Union representatives, who were the deal's other guarantors, have publicly disagreed on the sequencing. But Baqaei's restatement is notable for its timing: it came a day after the International Atomic Energy Agency's latest quarterly report, and on the same morning Iran's negotiating team had what Tasnim described as a "technical" call with the Omani mediators who hosted the original 2013 backchannel.

The Cradle's framing of the same remarks, in two near-identical posts at 15:19 UTC, gave the argument a more pointed edge. The English-language channel used the word "breached" twice in a single line, and led with a reference to "international commitments" rather than the JCPOA alone. The choice of language is itself a signal: it repositions the dispute from a narrow technical file on enrichment to a broader question of treaty compliance, where Iran's standing in the Non-Aligned Movement and at the UN General Assembly is more relevant than its standing at the P5+1 table.

Hormuz, by way of a side door

Two minutes before the JCPOA restatement, Baqaei moved to a different file. In comments separately circulated by Tasnim at 15:15 UTC, he argued that the United States is seeking control over the Strait of Hormuz, and he invoked "the fifth article of the memorandum of understanding" as the basis for Iranian management of the waterway. The reference appears to point at a long-standing bilateral understanding with Oman, under which the two states coordinate naval traffic and search-and-rescue in the strait, and which Iranian officials have occasionally cited to assert that no outside power has a unilateral role at the chokepoint.

The Hormuz move is not, strictly speaking, about the nuclear file. But it is not unrelated either. Roughly a fifth of the world's seaborne oil transits the strait, and any Iranian move to assert that the US Navy's presence there is illegitimate has knock-on effects for the enforcement of sanctions at sea. By choosing to bundle the two arguments in the same press window, Baqaei created a single narrative thread: Washington as the unilateral actor on both files, and Tehran as the responding party restoring balance.

What the framing is up against

The counter-reading is straightforward and Western capitals have made it publicly. The 2018 US withdrawal from the JCPOA was followed by a maximum-pressure sanctions regime that Iran argues is itself coercive; Washington, Brussels and London argue that Iranian enrichment above 3.67% and the development of advanced centrifuges are independent violations, not responses. European negotiators have pointed to a 2025 IAEA finding that Iran operated advanced centrifuges at Natanz in the early hours of a US–Iran prisoner exchange as evidence that the two tracks do not move in lockstep. Israeli analysts have argued in recent weeks that the Islamabad understanding was narrower than Iranian state media now presents it, and that Iran's announcement of new missile deliveries to allied militias in the region preceded any US action against the deal.

None of that is dispositive. The public record is genuinely contested, and the most that can be said with confidence is that the sequencing question is not one a court will resolve soon. What the day's briefing does is hand Tehran a clean sentence to repeat: we were not first. The repetition is the point.

The stakes on each side

For the United States, the practical question is whether the next round of sanctions enforcement can survive a sustained Iranian argument that Washington is the breach. For Iran, the question is whether a diplomatic posture that rests on a 2015 agreement the other parties no longer accept as binding can be sustained through a year of mounting domestic pressure on fuel and currency. For the European and Gulf mediators, the question is whether to treat the Islamabad track as alive, in which case Baqaei's line is helpful, or as already broken, in which case it is unhelpful. The Strait of Hormuz side door raises the stakes by adding a maritime dimension in which the US Fifth Fleet has direct operational interest, and where a miscalculation in the next quarter would be visible on shipping data within hours.

What is not yet visible, and what the sources do not give us, is the text of the Islamabad memorandum Baqaei invoked. Without it, both sides can keep saying the other was first. The argument will be settled, if it is settled, by what diplomats release and what the IAEA confirms. The next IAEA board meeting, scheduled for September, is the first clear date on the calendar; the Hormuz file has no such anchor and will instead move on the rhythm of naval movements and insurance underwriters.

How Monexus framed this: the wire copy on 18 July 2026 carried Iran's foreign ministry line at full length but did not give equal time to the European or Israeli counter-position; this piece pairs the Iranian argument with the publicly available rebuttals and flags the one document that would resolve the dispute, the unpublished Islamabad memorandum, that neither side has chosen to release.
