Trump Threatens '1,000 Missiles' On Iran, Iran's New Supreme Leader Vows Revenge For His Father's Killing

A Fragile Truce Is Falling Apart

The Iran war started February 28, 2026, when U.S. and Israeli strikes killed Iran's longtime Supreme Leader, Ayatollah Ali Khamenei, according to the Associated Press. The two sides eventually signed a memorandum of understanding in June, agreeing to halt military operations, reopen the Strait of Hormuz, and start a 60-day negotiation window, according to Forbes.

That deal is now cracking. Iran attacked three ships in the Strait of Hormuz earlier this week, according to the Associated Press, triggering days of U.S. airstrikes and Iranian retaliatory fire across the Middle East. Trump said this week the ceasefire was "over" and called further negotiations "a waste of time," according to Forbes.

The Funeral, The Threat, The Response

Iran buried Khamenei this week in a dayslong funeral procession that moved his body through cities in both Iran and Iraq, according to the Associated Press. Photos from the ceremony showed mourners holding signs calling for the deaths of both Trump and Israeli Prime Minister Benjamin Netanyahu, according to Newsweek.

Trump responded Friday night on Truth Social. "1000 Missiles are Locked and Loaded and aimed at the Islamic Republic of Iran, with thousands of more to immediately follow, should the Iranian Government act on its threat," he wrote, referring to what he called threats to assassinate him, according to the Associated Press. He added the U.S. military would "completely decimate and destroy all areas of Iran" for a year, "subject to extension," according to Forbes.

Trump has repeatedly invoked Arabic religious language during the war, closing this latest post with "PRAISE BE TO ALLAH!" The Council on American-Islamic Relations has previously criticized what it called Trump's "deranged mocking of Islam," according to the Associated Press.

Iran's new Supreme Leader, Mojtaba Khamenei, answered Saturday. In his first public message since his father's funeral, he wrote that "vengeance is the will of our nation and must inevitably be carried out," adding that "this matter depends neither on my personal existence nor on that of other officials," according to Al-Monitor. He said Iran has compiled a list of targets and that revenge "will be accomplished" whether he is alive or dead, according to Forbes. He did not name Trump directly, according to Axios reporting cited by Forbes.

Khamenei has not appeared in public since before the war began and was reportedly wounded in the same strike that killed his father, according to Al-Monitor and Newsweek.

What's Actually At Stake: The Strait

The practical fight is over the Strait of Hormuz, through which roughly 20% of the world's oil moves, according to Forbes. Iran closed the strait during the war and now wants to control ship passage through it and charge fees, according to Al-Monitor, a demand that breaks decades of precedent treating the strait as an international waterway.

U.S. officials, speaking to reporters on condition of anonymity, blamed the renewed fighting on a "rogue faction" of Iranian hard-liners trying to sabotage the ceasefire, according to the Associated Press. Iran disputes that characterization entirely, insisting its government is unified under Mojtaba Khamenei, according to the Associated Press.

If U.S. officials are right, this is a factional problem inside Iran that diplomacy could still isolate and fix. If Iran is right that its government speaks with one voice, then the fee demand and the strait closures are official state policy, not rogue sabotage, and much harder to negotiate away.

Iran's Foreign Minister Abbas Araghchi said Tehran has held up its end of the deal and that "there can only be mutual compliance," according to Al-Monitor. Iran's UN ambassador, Amir Saeid Iravani, said Iran remains committed to the memorandum "provided that the United States fully and faithfully complies with its own obligations," warning Iran would consider itself unbound if the U.S. keeps violating the deal, according to Al-Monitor.

Diplomacy Isn't Dead Yet

Even with the threats flying, mediators haven't given up. Iran's Tasnim news agency reported a Qatari delegation traveled to Iran on Friday to shore up Doha's role as mediator, according to Al-Monitor. Trump himself claimed less than 12 hours before his missile threat that the U.S. had agreed to an Iranian request to continue talks, according to Forbes, an inconsistency that shows how fast the rhetoric is swinging between rupture and negotiation.

A sitting U.S. president facing actual assassination calls at a foreign funeral has legitimate grounds to warn of massive retaliation, and deterrence only works if the threat is credible. Broadcasting a country-wide "decimate and destroy" threat, paired with religious language CAIR has called mocking, makes it harder for anyone in Tehran to publicly back down without looking weak.

No new ceasefire has been announced. No date has been set for the next round of talks. The Strait of Hormuz remains the unresolved flashpoint, and until Washington and Tehran settle who controls it, the shooting is likely to keep interrupting the diplomacy on both sides.
