Nuclear terrorism is the ultimate preventable catastrophe. If highly enriched uranium and plutonium are adequately secured or eliminated, they cannot be stolen for use in a nuclear device. In 2011, Director of National Intelligence James Clapper noted that "poorly secured stocks of [chemical, biological, radiological, and nuclear materials] provide potential source material for terror attacks." Osama bin Laden may be dead, but the threat of nuclear terrorism remains.
