Since the release of the 2012 NTI Index, seven states—Austria, the Czech Republic, Hungary, Mexico, Sweden, Ukraine, and Vietnam—have removed all or most of the stocks of weapons-usable nuclear materials from their territories, according to the U.S. National Nuclear Security Administration. In doing so, they have taken the most important step a state can take toward ensuring that terrorists cannot gain access to the materials needed to build a nuclear bomb. As a result, the number of states with one kilogram or more of weapons- usable nuclear materials is now 25, down from 32 when the 2012 NTI Index was released. This three-minute video highlights the actions of seven countries to remove their weapons-usable nuclear materials.
