Sabotage Ranking
Has Weapons-Usable Nuclear Materials


Iran ranks at the bottom of the sabotage 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 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 security conditions are adversely affected by political instability, governance challenges, and corruption.
