Iran and the timetable

How Close Is Iran to Having a Nuclear Bomb? (Economist-UK)
    British and American intelligence sources think Iran is about a year away from having enough highly enriched uranium to make a bomb, and rather further from mastering the technologies to make a nuclear warhead small enough to fit into a missile.
    But David Albright, a former UN weapons inspector who is president of the Institute for Science and International Security, thinks that by mid-2014 Iran will have the capacity to produce enough fissile material for a single bomb in one or two weeks, should it choose to do so.
