TRUMP’S ENDORSEMENT MIGHT BE THE ONLY SECURITY AGAINST GETTING BLOWN UP: Trump says he must be involved in picking Iran’s next leader.

President Trump told Axios in an interview Thursday that he needs to be personally involved in selecting Iran’s next leader — just as he was in Venezuela.

Trump revealed this exclusively in an eight-minute phone call — his second conversation with us to explain his war planning.

Why it matters: Trump acknowledged that Mojtaba Khamenei, son of assassinated supreme leader Ali Khamenei, is the most likely successor — while making clear he finds that outcome unacceptable.

For several days, the Iranian regime has postponed the announcement of the new supreme leader. But statements by Iranian politicians on Thursday suggested an announcement could be imminent.

What he’s saying: “They are wasting their time. Khamenei’s son is a lightweight. I have to be involved in the appointment, like with Delcy [Rodriguez] in Venezuela,” Trump said.

He added that he refuses to accept a new Iranian leader who would continue Khamenei’s policies, which he said would force the U.S. back to war “in five years.”

“Khamenei’s son is unacceptable to me. We want someone that will bring harmony and peace to Iran,” Trump said.

The big picture: Trump’s comments represent an extraordinary claim of American power over Iran’s political future, further muddying the objectives of the massive U.S. military campaign he launched on Saturday.

Muddying? I do not think that word means what you think it means, Axios.
