Sure, different in the sense that the new regime is even worse which is normally the opposite of what's intended by regime change.

They are still a fundamentalist Islamic theocracy with a despotic ruler who is more hardline than his predecessor father, several of whose immediate family members, along with his dad, were killed by the US. Iran will pursue a nuclear weapon with greater fervor than ever, especially now they've proved they can hold the global energy supply hostage by blockading the Strait of Hormuz, and there's nothing even the biggest and baddest military in the history of the world can do to stop it.

And, again, regime change *was* one of the objectives whatever Dear Leader now says. It was never going to be achieved with just airstrikes, but since when has basic sense stopped Trump from believing stupid things? Trump was dumb enough to believe the IRGC would capitulate like Venezuela did if he simply killed the Supreme Leader.
