The two discussed the conflict at length on Rogan's podcast, 'The Joe Rogan Experience,' on Thursday.

Rogan, 58, said toward the end, 'I'm confused. I can't believe we went into this war. When we started bombing Iran, I was like, "This can't be true."'

Von, 46, responded by decrying Israel's invasion of Lebanon, which Trump said he supports during a primetime speech the day before.

'It's like, just f*cking stop it. What do you need?' a visibly frustrated Von asked.

Rogan replied: 'Well, they're trying to, supposedly, they're trying to stop the terrorists,' putting emphasis on the word 'supposedly'.

Von exclaimed: 'That's crazy, though. You're the f*cking terrorists! You know what I'm saying?' The comic urged officials to reconsider their stance.

Earlier on, Rogan pointed out how the Iranian regime has a 'unique method of protecting their missiles from being bombed'. He said recent strikes were aimed at stomping out supplies kept 'deep underground.' 

Von said he didn't think 'we're over there doing that for ourselves, though' - paving the way for Rogan to agree.

'It doesn't seem like it. Doesn't seem like it's in our best interest, you know,' Rogan said.

Von wondered what 'Israel holds over America that we do those things.'

Rogan replied, roughly a year and a half on from his Trump endorsement, 'Well, first of all, there's a lot of people that donated to the Trump campaign that have significant influence over him, and they're very, uh, beholden.'

Rogan also observed: 'One thing, in the past, that leaders have used to cover up problems at home is a f*cking war.'

The clips quickly circulated on X as both men were credited with helping Trump to his second White House stay with widely viewed interviews in 2024. Both have also soured on Trump recently, at first because of the conservative's approach to immigration.

In December, Rogan told comedian Shane Gillis any type of war 'would be a terrible idea'. The conversation occurred just before the US's invasion of Venezuela.

Last month, Rogan called Trump's military aspirations in Iran 'insane'. He said Trump supporters should 'feel betrayed' by the US' strikes. Trump campaigned on an 'America First' foreign policy.

The president, on Wednesday, called the Iranian regime 'fanatical' and said it's been a threat to both the US and Israel for 47 years. 

He singled out a 1983 suicide bombing by Hezbollah on the United States Marine Barracks in Beirut that killed 241 US Marines and an Al-Qaeda terrorist attack on a US Navy warship in 2000 that killed 17.

'This murderous regime also recently killed 45,000 of their own people who were protesting in Iran - 45,000 dead,' Trump said. He added that the regime's strategy before the US's initial strikes on February 28 'was so obvious.'
