Preventing Nuclear Testing
Building the networks and coordinated action needed to help stop a return to nuclear explosive testing
Preventing Nuclear Testing is an initiative of Public Democracy America’s National Security and Democracy program. Led by Michelle Dover, the initiative connects specialized expertise, trusted relationships, and strategic coordination to help prevent a return to nuclear explosive testing.
The Challenge
A resumption of nuclear explosive testing could accelerate a global arms race, as well as create serious safety, environmental, and security risks for nuclear workers and communities near potential testing sites.
Key impacted constituencies remain disconnected from one another, particularly outside the traditional nuclear arms control and nonproliferation community. Local officials, affected communities, legal experts, environmental leaders, civic organizations, national security professionals, allied governments, and international institutions all have unique perspectives on the challenges. PDA’s Preventing Nuclear Testing initiative is designed to build those connections.
Our Approach
The initiative engages nuclear experts, advocates, civic leaders, public officials, and international partners to build relationships before a crisis demands immediate action.
