Iran's Islamic Revolutionary Guard Corps issued a Sunday statement giving the United States thirty days to end the naval blockade of Iranian ports. The IRGC framed Trump's choice in two phrases: "an impossible military operation or a bad deal." [1] [2] Ebrahim Azizi, head of the National Security and Foreign Policy Committee of Iran's Parliament, posted Sunday on X that "any American interference in the new maritime regime of the Strait of Hormuz will be considered a violation of the ceasefire." [3] The two statements together produce a thirty-day mirror of the same end-of-hostilities clause Trump's fourteen-point American counter-proposal wrote against Tehran on April 30.

The mirror is precise. Trump's counter — relayed through Pakistani intermediaries to Tehran on April 30 — gave Iran thirty days to end the war "on all fronts." Iran's Sunday counter gives Trump thirty days to end the blockade. Both windows close in early June. The Iran response is, as the Iran Diplomacy and Mediation thread memo has tracked since the fourteen-point release, the first time Tehran has imposed the same calendar on Washington that Washington imposed on Tehran. The parliamentary national-security commission's warning — issued by Azizi within hours of the IRGC statement — names Project Freedom as the trigger. [3]

Project Freedom — announced by Trump on Truth Social Sunday and confirmed by U.S. Central Command for May 4 — is the operational fact Iran has chosen to label. CENTCOM's package commits fifteen thousand sailors and Marines, more than one hundred land- and sea-based aircraft, guided-missile destroyers, and unmanned platforms. [4] U.S. officials clarified within hours that the mission is "coordination," not "escort"; CENTCOM will provide "real-time navigational intelligence" to merchant ships moving through the Strait. [5] Iran's view of the distinction is unsentimental. The IRGC's Sunday statement made no reference to coordination. Azizi's parliamentary statement made no reference to lanes. Both treat the operational presence — the metal in the water — as the violation.

The IRGC's "impossible military operation" line carries a specific meaning inside Iranian doctrine. The IRGC has, since 2014, deployed asymmetric anti-ship capabilities — fast-attack craft, swarming drones, anti-ship cruise missiles, and bottom-laid mines — calibrated to make a U.S. naval mission cost-prohibitive in the Strait's twenty-one-nautical-mile chokepoint. The "impossible" is the operational claim that the architecture is unforceable for a U.S. carrier strike group at acceptable risk. The "bad deal" alternative is the fourteen-point counter. One of the two has to happen by early June.

Tehran's parliamentary leadership echoed the IRGC line through Sunday. Mojtaba Khamenei said the future of the Strait would be one "without U.S. presence." [6] President Pezeshkian said any "extension of military operations" by the U.S. would force Iran to recalibrate. Both framed the window as thirty days.

What the United States Navy does on May 4 is the first test of the clock. If the first U.S.-coordinated transit moves cleanly — neutral-flag tanker, Iranian patrol observing but not engaging — the clock continues to tick without an inciting event. If a single incident occurs, the IRGC's "violation of the ceasefire" framework is operational, and the thirty-day clock becomes irrelevant. Either path forecloses the diplomatic option in different ways.

The Pakistani back-channel mediation that produced the fourteen-point counter is the only off-ramp left. Foreign Minister Ishaq Dar was in Tehran on Friday and is expected in Riyadh on Tuesday. [7] Pakistan's IMF tranche meeting May 8 is a separate file but a related calendar. Pakistan is the only government with credible relationships in both Tehran and Washington.

The clock starts Monday morning. So does Project Freedom.
