Iran's New Nuclear 'Understanding' with World Atomic Agency Explained On 2/22/21 at 9:26 PM EST A last-minute arrangement between the International Atomic Energy Agency and the Islamic Republic of Iran has so far ensured the survival of an embattled 2015 nuclear deal among major world powers while allowing Tehran to terminate certain transparency commitments known as the Additional Protocol.
