Mojtaba Called Trump’s Signature Worthless from a Location No One Has Disclosed

Correction, October 12, 2026: An earlier version of this article said Iranian ballistic missiles struck Prince Sultan Air Base on July 18, wounding twelve US service members and damaging KC-135 tankers. Those casualties and that damage occurred in a March 27, 2026 attack; Reuters reported that a July 18 Iranian missile attack set off shelter alerts in Al-Kharj and Yanbu, with no casualties reported. The earlier version also said Mojtaba Khamenei “voided” the Islamabad MOU in a statement read on state television; Reuters reported a written statement, carried by his official accounts and state media, calling Donald Trump’s signature “utterly worthless and devoid of credibility”, and Iran’s suspension of its commitments was announced by Deputy Foreign Minister Kazem Gharibabadi. The article also misstated the number of nights of US strikes (seven, not nine), the interval between Ali Khamenei’s death and his son’s appointment (eight days, not six), the MOU’s terms, the Hormuz pre-war baseline, and Oman’s role, and it wrongly said Saudi Arabia had no part in Islamabad when Pakistan credited it with helping to facilitate the agreement. These have been corrected. Unsourced material has been removed, including figures on Saudi interceptor stocks, a “Petroleum Goods and Services Agreement”, 2,300 US personnel at Prince Sultan Air Base, a twelve-to-one Supreme National Security Council vote, an Omani “first-ever condemnation” on July 19, earlier Mojtaba statements, rial exchange rates, a reported Saudi-Qatari call on July 20, and several quotes from officials and analysts that could not be verified.

TEHRAN — A written statement from Mojtaba Khamenei declared the signature of the President of the United States “utterly worthless and devoid of credibility” and warned that Iran holds “unforgettable lessons” for its adversaries. The statement was issued on July 18 as a written message carried by the Supreme Leader’s official accounts and Iranian state media, according to Reuters. Mojtaba did not appear. His whereabouts remain a mystery, Reuters reported. The Assembly of Experts named him Supreme Leader on March 8, eight days after his father was killed.

The managed ambiguity that allowed Iran, the United States, and Saudi Arabia to treat the Islamabad MOU as a living diplomatic instrument — despite the ceasefire’s functional collapse, despite seven consecutive nights of American strikes on Iranian territory, despite an Iranian missile attack that set off shelter alerts in Al-Kharj hours before the statement was issued — ended in a written text issued in Mojtaba’s name. Saudi Arabia is not a party to the MOU, though Pakistan credited it with helping to facilitate the agreement. No Saudi channel to the authority that issued the July 18 statement has been reported.

The Statement No One Saw Delivered

The message contained two operative declarations. The first: repeated US breaches of the agreement had shown that “the signature of the US President is utterly worthless and devoid of credibility,” in the translation carried by the Times of Oman. The second: “Now that the American enemy is seeking to escalate the conflict, thereby incurring even heavier costs and further humiliation, it should know that the noble nation of Iran and the Resistance Front have unforgettable lessons in store for it.”

The statement was issued in writing. No video or audio of Mojtaba Khamenei delivering it was reported. English translations quoted it describing America’s “dishonesty, irrationality, unreliability, and malicious nature.”

This is how Iran’s answer to the collapse of the Islamabad MOU reached the world: as a written text, attributed to a man whose whereabouts, Reuters reported, remain a mystery. Ali Khamenei, whatever his physical limitations in later years, delivered his major policy declarations in person, in front of audiences whose size and composition served as calibrated signals.

Mojtaba has reproduced none of this.

“The signature of the US President is utterly worthless and devoid of credibility. Coercion, totalitarianism, and brutality are inseparable components of the US creed and doctrine.” — Written statement attributed to Supreme Leader Mojtaba Khamenei, as translated by the Times of Oman, July 18, 2026

What Does Day 33 of the MOU Framework Mean for Saudi Arabia?

Signed June 17–18 with Pakistan as mediator, the Islamabad Memorandum of Understanding declared an end to military operations and set sixty days of toll-free passage through the Strait of Hormuz, the lifting of the US naval blockade within thirty days, a reconstruction plan of at least three hundred billion dollars, the release of frozen Iranian assets, and the deferral of enrichment questions to later talks. Day 33 of that window falls on July 20. Day 60 falls on August 16.

Saudi Arabia signed none of these provisions. Pakistan’s prime minister nonetheless credited it, alongside Qatar, Türkiye and Egypt, with helping to facilitate the agreement. It was excluded from the Oman-facilitated track.

Mojtaba’s statement, as reported, did not address the MOU’s specific provisions — the frozen assets, the reconstruction fund, Hormuz transit terms. It addressed something more fundamental: the capacity of the counterparty to make binding commitments. By declaring Trump’s signature “utterly worthless,” the statement rejected not a particular clause but the framework of American diplomatic credibility within which the MOU was constructed. For Saudi Arabia — which has spent interceptors defending against a war whose diplomatic framework was supposed to contain escalation — the consequence is that costs continue to accumulate against a framework whose American signature the only authority capable of validating it has declared worthless.

Deputy Foreign Minister Kazem Gharibabadi made the operational implications explicit on the same day, July 18, in remarks reported by Tasnim News Agency — declaring all Iranian commitments suspended, the United States having breached first, and Iran’s priority shifted to national defense. Gharibabadi’s formulation was carefully structured: Iran did not withdraw; it responded. The sequencing placed legal culpability on Washington while closing off the MOU as a diplomatic avenue.

Thirty Days from the MOU to the Statement

Exactly thirty days separate the Islamabad MOU’s entry into force on June 18 from Mojtaba’s July 18 statement. When Pakistan announced the agreement, Prime Minister Shehbaz Sharif commended Iran’s leadership, including Supreme Leader Mojtaba Khamenei, for embracing what he called the cause of peace, according to Anadolu Agency. As this publication analyzed on July 6, the Supreme Leader’s position was always the decisive variable.

In thirty days, the operational space available to those who had treated the agreement as a mandate to proceed — Pezeshkian’s government and Pakistan’s mediating team — has collapsed.

The pattern has precedent in the Islamic Republic’s management of the 2015 JCPOA, from which Trump withdrew the United States in May 2018. But the July 18 statement goes further. Mojtaba’s statement questions American capacity — not whether Washington will honor its commitments, but whether an American presidential signature constitutes a commitment at all.

Who Drafted the Words Issued in Mojtaba’s Name?

For Riyadh, the authorship question is structurally irrelevant. Whether Mojtaba composed the July 18 statement in his own hand or the IRGC drafted it and affixed his name, the operational result is identical. The only authority within the Islamic Republic capable of validating the MOU framework — or creating conditions for a successor framework — has declared the American signature on that framework worthless. No Saudi channel to Mojtaba has been reported. Nor has any to the IRGC command that may be operating under his name. The entity that made the declaration cannot be identified with certainty, and the entity whose authority gives the declaration its constitutional force cannot be located. His position, whoever authored it, is categorical.

“We have suspended our commitments under the Islamabad Memorandum … We have also suspended our commitments; we are not implementing them and are focused on defending the country.” — Kazem Gharibabadi, Iran Deputy Foreign Minister, as reported by Fars News Agency, July 18, 2026

Does Riyadh Hold Any Channel to the Authority That Rejected the Framework?

Saudi Arabia’s diplomatic architecture for the Iran crisis has consisted of three elements: Prince Faisal bin Farhan’s public commentary on frameworks negotiated by others, the armed forces’ military coordination with CENTCOM, and an informal back-channel through Oman. None of these channels reaches the decision-making authority that issued the July 18 statement.

The Omani channel had been functioning as a contact mechanism with Tehran: Muscat hosted Iran–Oman talks on managing the strait on July 11. Oman also summoned Iran’s ambassador to protest drone attacks in two regions on July 12.

Saudi Arabia’s remaining institutional option is the Pakistani channel. Pakistan mediated the Islamabad MOU, which Trump declared “over” on July 8. Islamabad retains institutional relationships with both the IRGC and civilian Iranian authorities. But Pakistan’s standing depends on its value as a mediator to all parties — value that diminishes proportionally with the diplomatic framework it mediated. If the MOU is dead, so is Pakistan’s role as its mediator. The suspension Gharibabadi announced July 18 removes the instrument that gave Islamabad its seat at the table.

What the MOU Would Have Changed

The MOU’s provisions, had they been implemented, would have addressed several of Saudi Arabia’s material constraints indirectly. A functional ceasefire would have reduced the rate of interceptor expenditure. Hormuz reopened toll-free would have restored the maritime corridor for Saudi Arabia’s Gulf-coast exports. The reconstruction plan of at least three hundred billion dollars would have created economic incentives for sustained Iranian compliance. Each of these provisions is now out of reach. Iran forfeits the reconstruction capital and frozen-asset release. Saudi Arabia forfeits the diplomatic cover under which interceptor resupply, ceasefire maintenance, and maritime normalization could have been negotiated.

Hormuz itself has been reduced to a fraction of its pre-war function. Before the war the strait handled 130 to 140 transits a day, according to Reuters. Iran said on July 12 that it had again closed the strait. The MOU was supposed to prevent exactly this: the strait’s commercial function has been effectively suspended, and the military operations intended to restore it now operate outside any diplomatic framework that might define their end state.

What Comes After a Framework Iran Has Suspended?

Both parties to the Islamabad MOU understood that the framework carried an expiration risk — sixty days of toll-free passage is a short window, and the underlying conflict over Hormuz, nuclear enrichment, and regional military presence predated the agreement by decades. What Mojtaba’s July 18 statement introduced was not expiration but invalidation. Expiration allows for renewal. Invalidation questions whether the counterparty ever held the capacity to commit.

No replacement framework is visible. Gharibabadi formalized Iran’s suspension on July 18. Mojtaba’s statement supplied the Supreme Leader’s constitutional authority to what had already become operational fact. The sixty-day clock continues to run — Day 33 of a framework both parties have declared inoperative — because no party has proposed an alternative mechanism for marking its end. August 16 will arrive as the end of a toll-free window attached to an agreement that no longer has signatories willing to claim it.

The military operations have outgrown the diplomatic container that was supposed to define their scope and duration. For Saudi Arabia, this means that the American military presence on and around its territory — the CENTCOM architecture that requires Saudi basing rights — now operates in service of objectives that are defined in Washington and Tehran without Saudi input.

For Saudi Arabia, the interval between now and August 16 presents constraints with no diplomatic solution currently available. The kingdom cannot negotiate directly with the authority that issued the July 18 statement because its author’s whereabouts are unknown. It cannot negotiate through Washington because the counterparty has declared the American signature worthless. The Pakistani channel loses its value in proportion to the instrument Pakistan mediated — and that instrument has been suspended. Meanwhile interceptor stocks are drawn down with every wave of Iranian strikes, and the Hormuz corridor remains under Iran’s declared closure.

Frequently Asked Questions

Has Mojtaba Khamenei made any verified public appearance since becoming Supreme Leader?

No verified public appearance has been reported. Reuters reported on July 18 that his whereabouts remain a mystery. The Assembly of Experts named him Supreme Leader on March 8, eight days after his father was killed.

Could the Islamabad MOU framework be revived after Mojtaba’s statement?

Any revival would face a structural obstacle: it would require Mojtaba — or whoever authors his statements — to reverse a position stated in his name.
