Summary

The United States is one of the most improved states in the theft ranking, with its score increasing by 3 points from 2014, and ranks 10th. The United States improved due to ratifying the 2005 Amendment to the Convention on the Physical Protection of Nuclear Materials and the International Convention for the Suppression of Acts of Nuclear Terrorism. In the future, the United States could improve its nuclear materials security conditions by requiring more frequent personnel vetting. The United States’ nuclear materials security conditions remain adversely affected by its high quantities of nuclear materials and the large number of sites at which those materials are located.
