In the single most operationally escalatory directive since the ceasefire began, Trump posted on Truth Social: "I have ordered the United States Navy to shoot and kill any boat, small boats though they may be (Their naval ships are ALL, 159 of them, at the bottom of the sea!), that is putting mines in the waters of the Strait of Hormuz. There is to be no hesitation." He simultaneously ordered mine-sweeping operations significantly intensified: "Additionally, our mine 'sweepers' are clearing the Strait right now. I am hereby ordering that activity to continue, but at a tripled up level!" In a separate post Trump declared: "We have total control over the Strait of Hormuz. No ship can enter or leave without the approval of the United States Navy. It is 'Sealed up Tight,' until such time as Iran is able to make a DEAL!!!" The directive came one day after the IRGC fired on three commercial vessels and seized two of them. Pentagon separately released footage of US forces boarding the Guinea-flagged M/T Majestic X in the Indian Ocean — previously named Phonix, sanctioned by US Treasury in 2024 for smuggling Iranian crude oil — making it the third vessel seized since the blockade began. Ship-tracking data placed the Majestic X between Sri Lanka and Indonesia, bound for Zhoushan, China — nearly identical location to the Tifani interdiction. The Pentagon statement: "We will continue global maritime enforcement to disrupt illicit networks and interdict vessels providing material support to Iran, wherever they operate." CENTCOM confirmed 33 commercial vessels directed to turn around or return to port since blockade day one — up from 31 on April 22. Iran vowed not to reopen the strait while the US blockade continued. Iran's Foreign Ministry noted the ceasefire extension but did not confirm readiness to resume talks. Brent crude crossed $100/barrel — up approximately 40% from pre-war levels — as ABC News reported no US warships are stationed inside the strait itself but enforce perimeter compliance.
CENTCOM announced that the Nimitz-class aircraft carrier USS George H.W. Bush (CVN-77) had entered the US Central Command area of responsibility in the Indian Ocean — the 10th and final Nimitz-class supercarrier. The Bush's arrival created a three-carrier presence in the region for the first time since the height of the US wars in Iraq and Afghanistan, per USNI News. The three positions: USS Abraham Lincoln (CVN-72) operating in the northern Arabian Sea enforcing blockade enforcement; USS Gerald R. Ford (CVN-78) in the Red Sea after transiting the Suez Canal from the Mediterranean following repairs in Croatia; USS George H.W. Bush (CVN-77) in the Indian Ocean. The Bush departed Naval Station Norfolk on March 31 and took the "long way" around Africa — via Cape Agulhas and the Mozambique Channel — deliberately avoiding the Bab el-Mandeb Strait, through which no US carrier has transited since the USS Dwight D. Eisenhower in December 2023, due to Houthi drone threats. The carrier sailed with destroyers USS Mason (DDG-87), USS Donald Cook (DDG-75), and USS Ross (DDG-71), and is equipped with a containerised LOCUST directed-energy laser weapon system for drone protection. Each carrier strike group carries approximately 6,000 sailors. Trump warned Iran: "The clock is ticking."
Following Trump's Truth Social post mocking Iran — "Iran is having a very hard time figuring out who their leader is! The infighting is CRAZY! We have total control over the Strait of Hormuz" — Iran's President Pezeshkian, Parliament Speaker Ghalibaf, and Chief Justice Mohseni-Ejei posted identical messages on X: "With ironclad unity of nation and state and obedience to the Supreme Leader, we will make the aggressor regret its actions." The slogan: "One God, one nation, one leader, one path." Supreme Leader Mojtaba Khamenei acknowledged their messages hours later in a further choreographed display. The Institute for the Study of War assessed the response as directed at both domestic regime factions and the United States — defending the three leaders from accusations of "moderation" from IRGC hardliners. The New York Times (April 23) and Israel Hayom both published significant revelations about Mojtaba Khamenei's physical condition: his leg has been operated on three times and he awaits a prosthesis; his hand was also operated on; he suffers severe burns to his face and lips, making it difficult for him to speak; he is expected to undergo multiple plastic surgeries. Access to him is described as "extremely difficult and limited" — commanders avoid visiting for fear Israel would track and strike the location. Iran is effectively being run by a "triangle of power" — IRGC generals Hossein Taeb, Mohsen Rezaei, and Ghalibaf operating as partners alongside the incapacitated Supreme Leader. Israel's Channel 12 separately reported Ghalibaf had stepped back from overseeing international negotiations following IRGC intervention. Vahidi prioritises ideological purity over the economy and views negotiations with the US as having "no present value." The $300 billion in economic damage and the case for a deal is being made by Pezeshkian and Araghchi — but the decisive tone belongs to the military.
Trump announced the Israel-Lebanon ceasefire had been extended by three weeks following what he called a "historic" meeting at the White House. The Oval Office meeting included VP Vance, Secretary Rubio, US Ambassador to Israel Mike Huckabee, US Ambassador to Lebanon Michel Issa, and high-ranking representatives of both Israel and Lebanon. Trump posted: "The Meeting went very well! The United States is going to work with Lebanon in order to help it protect itself from Hezbollah. The Ceasefire between Israel and Lebanon will be extended by THREE WEEKS." Rubio said Trump's direct involvement "made it possible" for the extension. Trump was asked whether he would consider deploying a nuclear weapon against Iran and responded bluntly: "No. Why would a stupid question like that be asked? Why would I use a nuclear weapon when we've, in a very conventional way, decimated them without it?" The comment addressed his earlier "a whole civilization will die" threat, which critics had interpreted as a nuclear reference. Pressed on a timetable for ending the war, Trump said: "Don't rush me." He added: "So we're in Vietnam, like, for 18 years; we're in Iraq for many, many years. I don't like to say World War II, because that was a biggie, but we were four and a half, almost five years in World War II." Trump: "Time favors the United States and not Iran." On the FIFA World Cup: Rubio confirmed Iranian footballers are welcome to participate, distancing Washington from proposals to have Italy replace them, but warned IRGC-linked delegation members could be barred from entry. Iran FM Baghaei acknowledged the ceasefire extension but did not confirm Tehran's readiness to attend a new round of talks. Miad Maleki (former Treasury): "We've never had the level of leverage that we have today with Iran since 1979."
Iranian state media reported that air defense systems were activated in parts of Tehran amid reports of "hostile aerial activity." The activation was the first reported engagement of kinetic defensive systems in the capital since the US-Iran ceasefire initially took effect. No strikes were confirmed; the nature of the aerial contact was not officially explained. The incident raised concern that either reconnaissance drones, surveillance aircraft, or other aerial assets had penetrated or approached Iranian airspace over the capital — suggesting the ceasefire's air dimension remains contested even as ground and naval operations draw most attention. Iranian authorities maintained throughout the day that Hormuz would not reopen while the US naval blockade of Iranian ports continued, with Ghalibaf's earlier characterisation of reopening as "impossible" remaining the operative public position. Iran's statements continued to position the maritime standoff as the primary obstacle to any diplomatic progress.
The "shoot and kill" order is the most consequential single directive of the ceasefire phase. It means US Navy vessels are now authorised to open fire on Iranian small boats — the same type used extensively in the Iran-Iraq War's "tanker war" and the IRGC's asymmetric doctrine. If executed, this transforms the ceasefire from a pause in airstrikes to an active naval war. The Khamenei medical revelations are equally significant: an incapacitated Supreme Leader who can barely speak, surrounded by IRGC generals who view talks as pointless, with Ghalibaf apparently sidelined from negotiations — this is the worst possible configuration for a diplomatic deal. The three-carrier presence brings US strike capacity to its regional maximum. The Majestic X seizure in the Indian Ocean — same coordinates as the Tifani — confirms the US has operationalised global enforcement, not just Gulf enforcement. The Tehran air defense activation is the most unsettling data point: something penetrated or approached the capital's airspace. The ceasefire's air dimension is not stable.
