US president signals he is not ready to back the Israel-aligned opposition figure to lead Iran in case of regime change.

United States President Donald Trump has ruled out meeting with Iran’s self-proclaimed Crown Prince Reza Pahlavi, suggesting that Washington is not ready to back a successor to the Iranian government, should it collapse.

On Thursday, Trump called Pahlavi, the son of Iran’s last shah who was toppled by the Islamic revolution of 1979, a “nice person”. But Trump added that, as president, it would not be appropriate to meet with him.

“I think that we should let everybody go out there and see who emerges,” Trump told The Hugh Hewitt Show podcast. “I’m not sure necessarily that it would be an appropriate thing to do.”

The US-based Pahlavi, who has close ties to Israel, leads the monarchist faction of the fragmented Iranian opposition.

Trump’s comments signal that the US has not backed Pahlavi’s offer to “lead [a] transition” in governance in Iran, should the current system collapse.

The Iranian government is grappling with protests across several parts of the country.

Iranian authorities cut off access to the internet on Thursday in an apparent move to suppress the protest movement as Pahlavi called for more demonstrations.

The US president had previously warned that he would intervene if the Iranian government targets protesters. He renewed that threat on Thursday.

“They’re doing very poorly. And I have let them know that if they start killing people – which they tend to do during their riots, they have lots of riots – if they do it, we’re going to hit them very hard,” Trump said.

Iranian protests started last month in response to a deepening economic crisis as the value of the local currency, the rial, plunged amid suffocating US sanctions.

The economy-focused demonstrations started sporadically across the country, but they quickly morphed into broader antigovernment protests and appear to be gaining momentum, leading to the internet blackout.

Pahlavi expressed gratitude to Trump and claimed that “millions of Iranians” protested on Thursday night.

“I want to thank the leader of the free world, President Trump, for reiterating his promise to hold the regime to account,” he wrote in a social media post.

“It is time for others, including European leaders, to follow his lead, break their silence, and act more decisively in support of the people of Iran.”

Last month, Trump also threatened to attack Iran again if it rebuilds its nuclear or missile programmes.

The US bombed Iran’s three main nuclear facilities in June as part of a war that Israel launched against the country without provocation.

On top of its economic and political crises, Iran has faced environmental hurdles, including severe water shortages, deepening its domestic unrest.

Iran has also been dealt major blows to its foreign policy as its network of allies has shrunk over the past two years.

Syrian President Bashar al-Assad was toppled by armed opposition forces in December 2024; Hezbollah was weakened by Israeli attacks; and Venezuelan President Nicolas Maduro has been abducted by the US.

But Iran’s leaders have continued to dismiss US threats. Iranian Supreme Leader Ali Khamenei doubled down on his defiant rhetoric after the US raid in Caracas on Saturday.

“We will not give in to the enemy,” Khamenei wrote in a social media post. “We will bring the enemy to its knees.”
