Many folks said that if the supreme leader got killed then it's all over. I honestly skeptical since IRGC folks would take over and I think they are much more militant than the Supreme Leader.
You are right to be skeptical. Khomeini died and now Khamenei is supreme leader. He too will have a successor if he dies (or is dead as Isreal clamed a moment ago). Iran has spent the last few weeks picking out successors four deep for each office. It's been the main news besides the "negotiations".
