The latest round of nuclear talks between Iran and the P5+1 (the five permanent Security Council members and Germany) held on Friday and Saturday in Almaty promised much. Iran’s chief nuclear negotiator, Saeed Jalili, had described the previous meeting (in February) as a ‘turning point’ and the foreign minister, Ali Akbar Salehi, had said negotiations were ‘on the right track and moving in the right direction’. Western diplomats, too, had expressed quiet confidence. Which was perhaps foolish. We have been here many, many times during the eleven years that this saga has rumbled on, and, sure enough, the latest round of talks broke down with each side blaming the other for the lack of progress. No common ground was reached; there wasn’t even an agreement to meet again for more talks.
