The US administration is signaling a shift in its Iran nuclear policy, moving from immediate military action to seeking a verifiable, long-term commitment from Iran not to rebuild its nuclear program. This shift is occurring amidst public admissions of strategic failures in the recent Iran war by VP Vance and public dissent between Vance and President Trump regarding the war. The US claims Iran's nuclear capabilities were destroyed during the conflict, though this remains unverified.
