With less than 24 hours remaining before U.S. President Donald Trump’s deadline to reopen the Strait of Hormuz expires, Iran has shown no sign of yielding. Instead, Tehran has doubled down on its military posture, vowing a “disproportionate” response to any American attack and launching long‑range missiles against U.S. strategic assets in the Indian Ocean.
The ultimatum, issued Saturday on Truth Social, gave Iran 48 hours to restore navigation through the strait, a chokepoint through which roughly 20% of global oil trade passes. “If the strait is not fully reopened within 48 hours, I am ordering the obliteration of Iranian power plants and energy infrastructure,” Trump wrote. The threat came after Iranian missile strikes on southern Israel on March 21, 2026 that wounded more than 100 civilians.
Iranian officials have publicly rejected the any form of deadlines. On Friday, Brigadier General Alireza Sabahifard, commander of Iran’s Khatam al‑Anbiya Air Defense Base, told state television that “any act of aggression will be met with a response that is no longer limited to an eye for an eye.” He added: “If the enemy attacks one infrastructure facility, we will attack several of theirs. We are making the enemy pay a heavier price for every mistake.”
The Islamic Revolutionary Guard Corps (IRGC) further raised the stakes on Saturday by releasing a list of targets it says would be struck in retaliation. According to a statement carried by the semi‑official Tasnim news agency, those targets include “all energy infrastructure, information technology systems, and desalination facilities belonging to the United States and its regional allies.”
Military operations have already expanded well beyond the Strait of Hormuz. On March 20, Iran launched a ballistic missile that traveled approximately 4,000 kilometers to strike near the joint U.S.‑British naval base on Diego Garcia, a remote atoll in the Indian Ocean. “This was the first time Iran demonstrated the capability to hit a target at that range,” said a U.S. defense official who spoke on condition of anonymity to Reuters. “It changes the calculus for assets far outside the Gulf.”

Regional allies of the U.S. have also come under renewed assault. The United Arab Emirates reported intercepting hostile aerial drones on Friday, and Saudi air defenses engaged missiles believed to be heading for Riyadh. Kuwait’s Mina Al‑Ahmadi refinery, one of the largest in the Middle East, sustained damage from a second strike this month, though no casualties were reported.
In his first public remarks since the conflict intensified, Iran’s new Supreme Leader, Ayatollah Mojtaba Khamenei, dismissed any form of U.S. ultimatums as a sign of “desperation.” In Eid al‑Fitr messages carried by state media, he declared that “the enemy has been defeated” and that American and Israeli strikes had failed to create “fear and despair” among the Iranian people. “The illusion that killing leaders will collapse this nation has proven hollow,” Khamenei said.
Analysts say Iran’s posture reflects a strategic decision to withstand economic and military pressure rather than capitulate. Oil tanker tracking data shows that no Iranian oil tankers are currently at sea, indicating Tehran has halted exports in anticipation of a wider confrontation. “Iran is signaling that it is prepared to endure the economic pain of a blockade to keep the strait closed and to pressure global energy markets,” said Helima Croft, head of global commodity strategy at RBC Capital Markets, in a note to clients.
U.S. officials have not yet detailed what form military action might take if the deadline passes. However, the Pentagon announced late Friday that it was moving additional F‑35 fighter squadrons to bases in Qatar and the United Arab Emirates, describing the deployment as “a defensive measure to protect American personnel and interests.”
With the clock ticking, Iran shows no sign of backing down. Foreign Minister Abbas Araghchi, speaking to Iranian journalists on Saturday, reiterated that “the presence or absence of a single individual does not affect Iran’s political and economic structure,” an apparent reference to the earlier killing of former Supreme Leader Ali Khamenei and other senior commanders. “We do not negotiate under threats,” Araghchi added. “The Strait of Hormuz is Iranian territory, and its security will be maintained by Iran’s armed forces—not by foreign ultimatums.”
