#NoGreaterThreat



We call on leaders to accelerate the effort to prevent catastrophic nuclear terrorism and continue their work beyond this last Summit to create global standards, accountability and best practices for securing all nuclear materials.



This week, global leaders gather for a final Nuclear Security Summit to take action to prevent terrorists from building and detonating a nuclear bomb. This requires securing and reducing nuclear bomb-making materials—plutonium and highly enriched uranium—around the world. Since the Summits began, 11 countries have eliminated nuclear weapons materials entirely. This is important progress, but the job is not done. The Summits are ending as the global terrorist threat is growing.

The United States and Russia, with the vast majority of the world’s nuclear materials and weapons, have a special responsibility to lead. The relationship between the U.S. and Russia has dangerously deteriorated, raising the risk of conflict instead of cooperation. We call upon the two countries to work to prevent ISIS and other violent groups from getting these materials and to avoid another costly arms race.



There is no greater threat to humanity and to the promise of our children's future than the nuclear threat. Our leaders must reverse our march down this risky path.





All nations must act to prevent nuclear terrorism and a new arms race.
