Summary

The United States scored in the top half of the NTI Index, though its score decreased by one point compared to 2012. The United States’ decline in score is due to its decision not to offer one facility for IAEA safeguards. In the future, the United States’ nuclear materials security conditions could be further improved by strengthening its laws and regulations for mitigating the insider threat, particularly by requiring more frequent personnel vetting, and by ratifying the 2005 Amendment to the Convention on the Physical Protection of Nuclear Material and the International Convention for the Suppression of Acts of Nuclear Terrorism. The United States’ nuclear materials security conditions also remain adversely affected due to its high quantities of weapons-usable nuclear materials and the large number of sites at which those materials are located.
