President Donald Trump has stated that the United States will not consider using nuclear weapons on Iran, despite previous statements that the U.S. intervened in the Iran war to prevent the Iranians from developing a nuclear weapon. He also warned of a nuclear holocaust in Europe and eventually in the US if the war did not occur. There have been disputes about Iran's potential nuclear capabilities, including former Director of the National Counterterrorism Center (NCTC) Joe Kent, who claimed that Iran was never on the verge of developing a naturating nuclear weapons. The administration has yet to specify the alleged "imminent threat" Iran poses to the US.
