Nuclear Threat Initiative

The Nuclear Threat Initiative is working to protect our lives, environment and quality of life for this and future generations from the growing risk of catastrophic attacks from weapons of mass destruction and disruption (WMDD)—nuclear, biological, radiological, chemical weapons and cyber nuclear.

The world has entered a new and dangerous era. Technologies, scientific know-how and deadly materials once held only by a few countries are now widely available. A growing number of individuals, well-financed terrorist organizations and states are seeking and developing the capacity to build and use these weapons. Governments struggle to keep up with the threat.

 Our operating model is unique. We design innovative threat reduction projects that we carry out with partners to directly reduce threats, to show governments the way and to build momentum and support for action on a larger scale.

We work with presidents and prime ministers, scientists and technicians, educators and students. We collaborate with partners worldwide. And we use our voice to raise awareness and advocate for creative solutions.

Founded in 2001 by former U.S. Senator Sam Nunn and philanthropist Ted Turner, NTI is guided by a prestigious, international board of directors. We rely on the generosity of donors to support our work. 

The dangers posed by weapons of mass destruction and disruption are among the most consequential facing the United States and the world. Reducing these dangers is challenging work. NTI is making a difference.
