Given Iran's nuclear history and support for terrorism, the United States is particularly concerned about Iran providing nuclear technology to other countries, the State Department said on Thursday. Spokesman Adam Ereli was responding to Iranian media reports quoting President Mahmoud Ahmadinejad as saying that Iran was "ready to transfer nuclear know-how" to fellow Islamic states. The comment, made during a meeting with Turkish Prime Minister Recep Tayyip Erdogan on the sidelines of the U.N. summit in New York, comes amid a serious dispute between the West and Iran over Tehran's nuclear intentions.
