Iran has drawn a firm red line in its standoff with the United States, telling Pakistan’s army chief, Field Marshal Asim Munir, that its enriched nuclear material will not leave the country. During his visit to Tehran, Munir met Iranian President Masoud Pezeshkian and other senior officials as Islamabad tried to revive negotiations between Washington and Tehran. Iran says talks cannot resume until its demands are addressed, including sanctions relief, an end to the U.S. blockade on Iranian ports and a halt to regional hostilities. At the heart of the dispute is Iran’s enriched uranium stockpile. Washington wants meaningful, verifiable limits on Iran’s nuclear programme, while Tehran insists it will not surrender its leverage without concessions in return. The disagreement also extends to the strategically vital Strait of Hormuz. Can Pakistan turn its diplomatic access into a breakthrough, or will the opposing demands keep negotiations deadlocked?
