What point are you trying to make here? I said Israel obviously wants Iran gone and stands to gain a lot from doing so. You didn’t address either of those points, which are extremely relevant when trying to understand why foreign powers want this regime removed and would be involved in its removal.
I agree Israel is not a US proxy (the tail wags the dog in this relationship), but freeing oneself from needing the (or any) dog is a sizable gain. Regarding Iran I think they know this. Their military is structured to operate in a post regime world. But that world doesn’t have the capacity to produce nuclear weapons, which is the key goal Israel is after. Iran with nuclear weapons likely ensures the regimes existence for the foreseeable future.
