At the end of the day its hard to see what benefit attacking Iran has for the US besides assisting Israel in its objectives to destroy the middle east Muslim countries for its own benefit. The US military is spread very thin via the pacific for China, the Ukraine debacle, and the Venezula/Cuba aggression. Our supplies are low missile wise due to Biden's aid and Trump's continued aid to Ukraine. The reality is, if we have to do a long, endurance style war vs Iran, we will be in a pinch and will look silly if we do not achive regime change in Iran. If the Supreme leader Ayatola is dead or not will not really change that. From what ive heard and read he assumed he would be killed very early in this conflict and picked others to lead. Do the Iranaian people rally to the next leaders cause? I think so. In January when the riots happened (CIA and Mossad initiated) they failed, and hundreds if not millions of Iranians rallied to their governments cause.
