Pakistan Army Chief Asim Munir’s visit to Tehran has raised questions about Islamabad’s efforts to revive U.S.-Iran peace talks, as Iran reportedly sends mixed signals on negotiations. While President Masoud Pezeshkian welcomed Munir warmly, videos of his meeting with Iranian security official Rezaei showed a more formal and reserved greeting. The diplomatic effort faces another hurdle over Washington’s demand for limits on Iran’s nuclear programme, with Tehran rejecting the prospect of transferring even a small amount of enriched uranium.
