The Terrorist Threat to the Homeland
Violent Extremism in the United States
The primary terrorist threat inside the United States will stem from lone offenders and small cells of individuals, including Domestic Violent Extremists (DVEs) and foreign terrorist-inspired Homegrown Violent Extremists.
[...]
Among DVEs, racially and ethnically motivated violent extremists—specifically white supremacist extremists (WSEs)—will remain the most persistent and lethal threat in the Homeland. Spikes in other DVE threats probably will depend on political or social issues that often mobilize other ideological actors to violence, such as immigration, environmental, and police-related policy issues.
WSEs have demonstrated longstanding intent to target racial and religious minorities, members of the LGBTQ+ community, politicians, and those they believe promote multi-culturalism and globalization at the expense of the WSE identity. Since 2018, they have conducted more lethal attacks in the United States than any other DVE movement.
