IN “IRAN’S nuclear deception” (Op-ed, March 11), William Tobey casts unfounded doubt on a recent finding by the International Atomic Energy Agency that a past error in Iran’s low-enriched uranium inventory was due to normal measurement uncertainties. He conjectures that Iran has undercounted deliberately to test and even cheat the atomic agency in preparation for “future non-compliance.” This is nonsense, a throwback to the Iran-phobia of the previous US administration, and omits the pertinent empirical facts about Iran’s peaceful nuclear program.
