Trump calls Iran's reply 'TOTALLY UNACCEPTABLE' as Khamenei orders military to 'confront the enemy'

The diplomatic track between Washington and Tehran came under severe strain Sunday after President Trump publicly rejected Iran’s formal ceasefire reply as “TOTALLY UNACCEPTABLE” and threatened to resume intensive bombing if Iran failed to accept US terms on the Strait of Hormuz and nuclear rollback. Within hours, Supreme Leader Mojtaba Khamenei issued new military directives to Iranian armed forces to “confront the enemy” following a meeting with Joint Chiefs commander Ali Abdollahi, who declared that forces are “locked onto enemy targets.”

The dueling statements landed on the same day Iran submitted its formal written response to the US memorandum of understanding through the Pakistani diplomatic channel — the same back-channel described in Iran’s initial reply to the US war-ending proposal. The collision of Iran’s diplomatic submission and its Supreme Leader’s combat orders illustrates the internal tension that has defined Tehran’s posture throughout: a government willing to negotiate and a military-clerical apparatus unwilling to appear to yield.

What Iran submitted and why Washington rejected it

Iran’s reply passed through Islamabad and reached US counterparts Sunday, according to officials familiar with the channel. Tehran’s position, as reflected in the submission, retained significant reservations on the two issues the Trump administration designated non-negotiable: full Hormuz transit guarantees and verifiable nuclear rollback to pre-2019 levels. The gaps between the two positions were analyzed in detail in Iran’s MOU Reply: What the Gaps Mean and Where Talks Go Now.

Trump did not release the text of Iran’s reply. His public rejection was delivered in all-capital letters on Truth Social and followed by a statement from a senior administration official that the United States would “consider the ceasefire lapsed” if Iran did not return with an acceptable counteroffer within a period the official declined to specify. The administration did not announce a deadline, leaving the door technically open while signaling maximum displeasure.

Khamenei’s military meeting and the “confront the enemy” directive

Hours after Iran’s reply was transmitted, Khamenei convened a session with Abdollahi, the commander of Iran’s Joint Chiefs. The state-affiliated WION News account of the meeting quoted Abdollahi saying Iranian forces had targeting solutions on “enemy assets” and were prepared to execute on command. The phrase “locked onto enemy targets” is the same language the IRGC Aerospace Force commander used in a post earlier this week and reflects a consistent public posture from the hardline military faction.

Whether Khamenei’s directive represents a genuine shift in operational orders or a public signal calibrated to manage domestic hardliner pressure is the interpretive question that intelligence analysts in Washington and Gulf capitals will be working through Monday. The timing — simultaneous with diplomatic submission — could reflect internal government fragmentation: the foreign ministry and president’s office managing the negotiation lane while the Supreme Leader and IRGC manage the deterrence lane, each telling a different domestic audience what it wants to hear.

Drones strike commercial shipping; UAE and Kuwait repel attacks

Sunday’s diplomatic breakdown coincided with continued kinetic pressure in the Gulf. A drone struck a commercial cargo vessel approximately 23 nautical miles northeast of Doha, sparking a fire that the crew extinguished without casualties, Fortune reported. The UAE intercepted two additional drones attributed to Iranian origin, and Kuwait reported repelling separate incursions into Kuwaiti airspace. No casualties were confirmed in any of the three incidents.

The pattern — drone harassment of commercial shipping and Gulf-state airspace running in parallel with diplomatic exchanges — has become the baseline operational tempo of the conflict since early May. Iran has not claimed the drone strikes; US and Gulf officials attribute them to IRGC proxy networks. The same pattern produced the UAE air-defense intercepts described in earlier reporting on Hormuz escalation, suggesting the frequency of drone activity has not diminished despite the ceasefire negotiations.

China and Russia in the nuclear lane

In a parallel diplomatic channel, Iran confirmed Sunday that it is conducting consultations with China and Russia on nuclear matters even as the US track proceeds, Newsweek reported. The consultations are formal and pre-scheduled rather than crisis-driven, but their timing — on the day Washington rejected Iran’s formal reply — will complicate the US position. China has sought to position itself as a constructive mediator; Beijing’s role in the Trump-Xi summit diplomacy on Hormuz remains the most significant external variable in whether the US-Iran channel can be repaired.

Beijing has leverage Tehran values: access to Chinese financial infrastructure that partially offsets US sanctions, diplomatic cover at the UN Security Council, and potential technical assistance on civilian nuclear matters that gives Iran an alternative path to the enrichment program the US is demanding it dismantle. Whether China uses that leverage to move Tehran toward a workable US offer or to protect its own economic interest in a prolonged Iranian dependency is the strategic question the Trump administration cannot yet answer.

Markets

Brent crude was trading at $101.29 per barrel and WTI at $95.42 on Sunday, holding near the week’s highs after Friday’s partial recovery from a de-escalation dip. Spot gold was quoted at $4,715 to $4,720 per ounce. Both benchmarks had partially priced in a ceasefire scenario during the week; Sunday’s breakdown reintroduces the war premium that had been bleeding out of commodity markets since Tuesday.

The Brent figure above $100 reflects the market’s sustained view that Hormuz disruption risk remains elevated regardless of diplomatic signals. A complete ceasefire, if one could be achieved and verified, would likely push Brent back toward the $85–90 range that analysts modeled before the current escalation cycle. Sunday’s events moved that outcome further out.

What to watch

The next 48 hours will determine whether Sunday’s mutual rejection is a negotiating-posture reset — both sides staking out extreme positions before a compromise — or a genuine collapse of the Pakistan channel. Key indicators include: whether Tehran returns with a modified offer or goes silent; whether the White House sets a public deadline for resumed strikes; whether additional commercial vessels are targeted in Qatari or UAE waters; and whether Beijing engages publicly to push talks back from the edge.

The IRGC’s stated posture — missiles and drones locked on US assets, forces prepared to execute on command — is designed to deter rather than to initiate. Whether that deterrence calculation holds if Washington announces resumed airstrikes is the question the next cycle of diplomacy will have to answer.
