Progress & Challenges
Measurable progress has been made toward the goal of reducing and securing the materials needed to build a nuclear bomb. But much more work needs to be done.
Global leaders must develop an effective nuclear materials security system around the world’s most dangerous materials. The system should be common and comprehensive, and should hold states accountable for the shared responsibility to prevent nuclear terrorism.
The number of states with weapons-usable nuclear materials has dropped from 32 to 25 in just two years, showing real progress in the global effort to prevent nuclear terrorism. NTI applauds the seven states that removed all or most of these dangerous materials from their territories since the inaugural NTI Index was released in 2012.
