Terrorism remains a threat to U.S. citizens, assets, and interests despite the national security community’s decreasing focus on counterterrorism. In 2025, domestic terrorism represents a greater threat to the United States than do international terrorist organizations. Most domestic terrorist attacks in the United States are carried out by lone actors or small groups who believe in a wide range of ideologies, such as white supremacy, partisan extremism, and Salafi-jihadism.
