Iran’s Supreme Leader Ayatollah Ali Khamenei has called for the formation of a united national front to resist what he described as U.S. attempts to subjugate Iran. “Never will the Islamic Republic bow to America,” he declared in a Sunday address. Khamenei linked last June’s joint Israeli-U.S. attack on Iran’s nuclear facilities to broader efforts to destabilize the country. Meanwhile, Iran is preparing to reopen negotiations with world powers over its nuclear program, signaling a new round of diplomacy amid escalating tensions.
