If regime change were on the cards for Iran, a lot more would be presently underway than we’ve seen so far. In context, Israel and America have managed to nearly completely destroy the capability of the former Supreme Leader. This doesn’t imply the fall of Iran is on its way, and neither is it an indication of any sort of plan or purpose.
As things go in the Middle East it’s usually those defending and that which is being defended that is targeted. It can result in missiles falling in the wrong places, but it can also be the fault of a bad state actor who is trying to repel action to deescalate and dismantle their illegal, centralised form of power.
