Iran installed a new supreme leader on Sunday. By Monday, the Wall Street Journal was reporting that President Trump has told aides he would back that leader's killing if he refuses to cooperate with U.S. demands.
The message from Washington could not be clearer: the name on the door changed; the deadline did not.
The New York Post reported that on Sunday, Iran's Assembly of Experts named Mojtaba Khamenei as the new Supreme Leader of Iran. He succeeds his father, Ali Khamenei, who was killed in the opening wave of U.S.-Israeli joint strikes.
Mojtaba Khamenei, 56, was appointed over the weekend following the death of his father, who was killed in the opening wave of the U.S.-Israeli joint attacks on February 28.
President Trump has told aides he would support killing Iran's new Supreme Leader Mojtaba Khamenei if he refuses to comply with U.S. demands, including ending Iran's nuclear program, according to a report by the Wall Street Journal citing current and former U.S. officials.
Officials cited by the Wall Street Journal described Mojtaba Khamenei as a hardline successor to his father who was chosen with backing from Iran's Islamic Revolutionary Guard Corps. The officials said they do not expect the new leader to abandon Iran's pursuit of nuclear weapons or agree to end the conflict on terms favorable to the United States.
Iran had a chance to turn the page. Instead, it reprinted the same one.
Mojtaba Khamenei is not a fresh face with a different vision. He spent years operating behind the scenes in his father's government, managing family finances, and, according to accusations referenced in leaked diplomatic cables from the 2000s, allegedly securing the appointments of regime loyalists in Iran's presidential elections. The IRGC didn't select a reformer. They selected continuity with a different name.
Trump had already made his feelings known. He said plainly: "They are wasting their time. Khamenei's son is a lightweight. I have to be involved in the appointment." He called Mojtaba's selection "unacceptable" and said the new leader "is not going to last long" without Trump's approval.
"I'm not going through this to end up with another Khamenei."
Trump made that point in an interview with Time magazine last week. It wasn't a throwaway line. It was a statement of objectives.
On February 28, 2026, Ali Khamenei, the supreme leader of Iran, was assassinated as part of a series of Israeli airstrikes around Tehran aimed at high-ranking Iranian officials. Khamenei's death was confirmed by the Iranian government on March 1. His death occurred as part of a wider joint operation by the United States and Israel.
The strike was not a rogue action. The strikes came in the wake of failed talks between Washington and Tehran as Trump pressured Iran to commit to abandoning its pursuit of weapons-grade uranium.
Trump's envoys for the nuclear talks, Jared Kushner and Steve Witkoff, had conducted "serious negotiations" with the Iranians but felt ultimately that the Iranians were not willing to compromise on U.S. demands.
After the latest round of talks in Geneva, Kushner and Witkoff told Vice President JD Vance over the phone that talks "aren't going anywhere, we're very disappointed."
Iran had every opportunity to avoid what followed. It chose its nuclear ambitions over its own leadership's survival.
According to the Wall Street Journal, Trump has privately indicated he would back the killing of Khamenei if the new leader refuses to meet U.S. demands, such as halting Iran's nuclear development.
Two officials cited in the report said Israel would likely carry out any operation targeting Khamenei, noting that Israel has taken the lead in operations against senior Iranian leaders.
The framework is not complicated. According to the Wall Street Journal, the president "would back" the killing of Mojtaba if he, like his father, refused America's demands. Chief among them is the end of Iran's development of nuclear arms.
Trump told the New York Post on Monday that he was "not happy" with the pick. He also told the Iranian regime exactly what he wants from them:
"We want someone that will bring harmony and peace to Iran."
That is not an unreasonable request. It is, in fact, what the Iranian people themselves have been asking for decades. As Khamenei's death was confirmed, many Iranian civilians went out to celebrate in the streets. The regime's grip on power has never reflected the will of the people it commands.
The IRGC thought it could absorb the loss of Ali Khamenei and reconstitute authority under his son. That calculus may be correct domestically. It is almost certainly wrong internationally.
Mojtaba Khamenei inherits a regime that just lost 49 senior officials in a single strike, a supreme leader who was killed on his own compound, and a nuclear program that the United States has made the explicit condition of his survival.
He also inherits a country where his father's death was, for a portion of the population, a cause for celebration rather than mourning.
The IRGC bet on continuity. Trump is betting on consequences. One of those positions has the weight of demonstrated action behind it.
Iran can negotiate. It can abandon a nuclear program that has brought it nothing but isolation and military strikes. Or it can test whether the administration's private signals match its public ones. Given what happened on February 28, that is a test Mojtaba Khamenei should think very carefully about taking.
The father refused to deal. The son now holds the same cards and faces the same ultimatum. The only question is whether he is smart enough to play them differently.
