Theft Ranking
Has Weapons-Usable Nuclear Materials


Iran’s score is unchanged from 2014 and it continues to rank near the bottom of the theft ranking. The lack of available information on Iran’s nuclear security—it does not publish its nuclear security laws and regulations or other information—impacted Iran’s low score. If it published this information, its score in a future edition of the NTI Index might increase. Iran could also further improve its nuclear materials security conditions by ratifying key international legal agreements, undertaking voluntary commitments, taking steps to build confidence in its security, and establishing an independent regulatory agency. Iran’s nuclear materials security conditions remain adversely affected by political instability, governance challenges, and corruption.
