I think Trump was basically broadcasting to the Iranian people to be ready to take over and made a calculation that if we degrade the iran govt to a certain degree, we wouldnt need to worry about the regime change part of this
The differences between Iran and Iraq/Afghanistan is Iran had a singular identity before. They were a Persian state, unlike a group of disparate tribes and identities in Iraq/Afghanistan. Much easier in the aftermath as they won't be trying to cobble together a coalition.
Having said that, the goals for Iran are pretty simple: no nukes, cut ballistic missiles severely, no more proxies in funding nor support and inspections allowed to verify these.
