Tehran's Supreme Leader declares US signature 'worthless' as fighting resumes
In a written statement on 18 July 2026, Iran's Supreme Leader Mojtaba Khamenei called US adherence to a bilateral memorandum 'worthless,' punctuating what Iranian and pro-Tehran channels described as a resumption of fighting with American forces.
At 16:36 UTC on 18 July 2026, Iranian state broadcaster Press TV posted a written statement from Ayatollah Mojtaba Khamenei on its Telegram channel, denouncing what he called repeated American violations of a memorandum of understanding between the presidents of Iran and the United States. Within minutes, identical passages had propagated across at least five Iran-aligned Telegram feeds, including Fotros Resistance, Clash Report, GeoPolitical Watch, WFWitness, and DD Geopolitics, each carrying overlapping fragments of the same Persian-language text.
The statement, as relayed verbatim by those channels, characterised the alleged US breaches as proof of "the worthlessness and invalidity of the American president's signature." Khamenei used the phrase "Great Satan," the standard Persian epithet for the United States used by Iranian state media for decades, and said Washington's behaviour had "once again revealed its true, unmasked face, so that this dark episode" of relations would be remembered. Two of the channels, bricsnews and Fotros Resistance, framed the remarks as a response to a resumption of fighting between Iranian and US forces.
What the statement actually says
Press TV's Telegram post, timestamped 16:36 UTC, is the earliest version of the text available in the thread. It opens by calling the alleged US violation of the MoU "worthless and invalid" proof regarding the value of the American president's signature. The second bullet, partially visible in the WFWitness repost at 16:38 UTC, accuses Washington of having previously and repeatedly violated the same understanding, framing each breach as confirmation rather than surprise.
DD Geopolitics, in its 16:44 UTC repost, rendered the line as: "The violation of the MoU once again proved the worthlessness and invalidity of the American president's signature." GeoPolitical Watch's 16:43 UTC version substitutes "Memorandum of Understanding" for "MoU" and adds a clause asserting that the signature itself "is not worth the pap[er it is written on]" in Farsi idiom. The variant phrasing is cosmetic. The substance, that the US president cannot be trusted to honour what he signs, is identical across all five feeds and matches the Press TV original.
Why the channels matter and what they don't tell us
Every source in this thread is either Iranian state media or a channel that carries Iranian state-media framing without independent attribution. Press TV is operated by the Islamic Republic of Iran Broadcasting. Fotros Resistance, Clash Report, DD Geopolitics, GeoPolitical Watch and WFWitness are not state organs, but each reposted the same Persian-language text within eight minutes, indicating either coordinated sourcing or rapid reposting of a single upstream release, almost certainly from Khamenei's own office or the Iranian Supreme Leader's spokesperson channel.
What none of the channels substantiate is the underlying factual claim that fighting has resumed between Iranian and US forces, or that Washington has violated any specific provision of the MoU. The bricsnews and Fotros Resistance headlines assert a resumption of hostilities, but no casualty figures, no location, no order of battle, and no independent confirmation from Western wire, United Nations, or Iraqi or Gulf-state sources appears in the thread. Reuters, the Associated Press, Agence France-Presse, the BBC, and Al Jazeera English have not been sighted in this cluster; the pipeline has, for the moment, only one side of the story.
What the framing is doing
The "worthless signature" line is not a fresh construction. It recurs in Iranian official discourse whenever Tehran wants to mark a relationship with Washington as broken beyond ordinary diplomatic repair. The structural purpose is to raise the cost, for any future US administration, of re-engaging Tehran on terms that the Islamic Republic regards as imposed rather than negotiated. By pre-emptively declaring any signature worthless, the statement narrows the room in which an American negotiator can claim credit for delivering a deal.
This is the plain-language version of what Western Iran-watchers usually call "maximalist rhetoric" or "strategic deadlock." It functions as a public marker that Tehran considers the bilateral channel, for now, closed, and that any future opening must be built on terms that re-credit Iranian sovereignty over the terms themselves. Read alongside the simultaneous "resumption of fighting" framing on bricsnews and Fotros Resistance, the statement operates as both a diplomatic epitaph and an operational signal.
What to watch next
Three concrete indicators will tell readers whether the escalation is rhetorical or kinetic. First, whether Iranian state outlets beyond Telegram, IRNA, Tasnim, and the Iranian Foreign Ministry's official page, publish the same text, which would confirm the statement's official status rather than a draft. Second, whether CENTCOM, the US State Department, or the White House issues a public response; silence from Washington is itself a signal that the statement is being treated as posturing. Third, whether any independent reporting emerges from the Persian Gulf, Iraq, or the Strait of Hormuz describing actual movement of naval or air assets consistent with the "resumption of fighting" framing.
For now, the verifiable record is narrower than the headlines suggest: one written statement, six repostings, no independent corroboration of resumed hostilities, and no confirmed violation of any specific MoU clause. The Iranian position has been stated in the strongest possible terms. The American position, as of 16:57 UTC on 18 July 2026, has not been heard in this thread at all.
Desk note: Monexus is carrying this story on the strength of Iranian and Iran-aligned Telegram channels because no Western wire confirmation has reached the pipeline. The "resumption of fighting" framing in two of the headlines is treated as a Tehran-aligned claim, not as established fact. Readers seeking operational confirmation should wait for CENTCOM, State Department, or major-wire reporting before treating the situation as kinetic.
