ADVERTISEMENT The federal government must begin by investing in existing efforts to prevent violent extremism while working to understand the nexus between public health and extremism. The government must get better at tracking and analyzing data, and support democracy-strengthening programs and efforts to build social cohesion, especially at the community level, in places where there is significant risk of violent conflict. The U.S. could learn from its decades of international assistance to conflict-affected and fragile states. Organizations in the U.S., including some that have worked overseas, are working to prevent violent extremism, strengthen democratic institutions, advance criminal justice reform, collect accurate data on violence, provide trauma healing to communities in need, and reduce political and community violence. This work is vital, yet sorely underfunded and insufficient to address the magnitude of the crisis.
