Well, the Israelis require an uprising under a reliable and believable opposition leader as a major ground force to enact regime change in Iran, and that doesn't appear to be happening. Although it appears that Israel is mostly operating at will within Iran in SF groups, presumably with local help.
Iran either needs to cross two countries to get to Israel or convince other local nations to attack Israel, otherwise this really goes nowhere and they continue to fire missiles at each other.
Leaving a power vacuum at the top of Iran doesn't feel like a workable plan.
