According to a report by The Telegraph on Sunday, March 08, 2026, U.S. President Donald Trump has warned that Iran’s newly appointed supreme leader will not “last long” if Washington does not approve of him.
Iranian authorities announced a successor following the assassination of Ali Khamenei in an airstrike last week, though they have yet to officially name the new leader. Many analysts expect the role to be assumed by Khamenei’s son, Mojtaba.
Speaking to ABC News on Sunday, Trump said, “He’s going to have to get approval from us … If he doesn’t get approval from us he’s not going to last long.”
Trump emphasized the strategic stakes, adding, “We want to make sure that we don’t have to go back every 10 years, when you don’t have a president like me that’s not going to do it.” He further noted, “I don’t want people to have to go back in five years and have to do the same thing again or worse, let them have a nuclear weapon.”
The remarks underline Washington’s continued focus on Iran’s leadership and nuclear ambitions amid ongoing regional tensions. U.S. officials have long expressed concern over Iran’s potential to develop nuclear weapons, a situation Trump has repeatedly stated must be prevented.
Analysts note that any direct involvement or implicit influence over Iran’s supreme leadership would represent an unprecedented level of foreign intervention, raising complex legal and diplomatic questions.
The announcement of Khamenei’s successor comes at a time of heightened volatility in the Middle East, with regional powers closely monitoring Iran’s political and military movements.
Trump’s statements signal an uncompromising stance, indicating that U.S. approval—or lack thereof—could play a decisive role in the stability of Iran’s next leadership. International observers continue to assess the implications for nuclear policy and broader regional security.
