Podcaster Joe Rogan slammed President Donald Trump for waging an "insane" series of strikes in Iran after running for election by promising not to start wars for regime change.During a Tuesday conversation on Rogan's podcast, author Michael Shellenberger said he had scrapped a column on the war in Iran because Trump's reasoning was unclear."But it's not clear that they're really out for regime change or they're just asserting power," he explained. "I mean, some of it's art of the deal, changing the person that we're negotiating with. That's Venezuela and Iran. Is it really going to change those regimes? I don't think — most people don't think so, but I'm not sure that that's what they're going for.""Well, neither thing made any sense to me," Rogan replied. "The Venezuela thing, I mean, look, they wanted him out forever.""They go in, kidnap him, get him out," he continued. "This one's nuts. Like, and what's happening in Tel Aviv. It's hard to know what's real and what's not because there's a lot of fake video going around and a lot of weird posts on X.""They might say that we want that or whatever, but that's not ultimately; they're not acting on the basis of achieving regime change," Shellenberger insisted."But just seems so insane based on what he ran on," Rogan remarked. "I mean, this is why a lot of people feel betrayed, right? He ran on no more wars and these stupid, senseless wars, and then we have one that we can't even really clearly defined why we did it."
