After the Twelve Day War of June 2025 in which Israel and U.S. attacked Iran’s nuclear facilities, relations between Washington and Tehran have entered their most dangerous and decisive period since the Iranian Revolution of 1979. This talk will explore if this crisis has opened a new path toward US-Iran dialogue—or whether the last bridge to peace been burned – as both capitals reassess their strategies amid a shifting balance of power in the Middle East. It also will assess if a new US-Iran nuclear deal is possible and the regional and global implications for deterrence, diplomacy, and peace if no deal can be reached.
