Where does an isolated Iran go from here?

Operation Epic Fury, a joint US-Israeli military offensive against Iran, has ignited a regional conflict, prompting discussion on Iran's options and the potential for regime collapse. The strikes began with decapitation attacks, including the assassination of Supreme Leader Khamenei, followed by targeting military infrastructure. Despite unprecedented concessions offered by Iran during nuclear talks, the US, under President Trump, pursued broader demands regarding ballistic missiles and regional activities. The Gulf states, while seeking de-escalation, find themselves caught in the crossfire, with civilian infrastructure increasingly targeted. While diplomacy remains a possibility, the lack of clear endgame from Washington and Iran's initial unwillingness to negotiate pose significant challenges.
