Why do people join domestic violent extremist organizations? This paper from Danny Klinenberg, an IGCC nonresident fellow, examines an understudied reason: organizational outreach. Klinenberg studies how the inflow of new members to the Oath Keepers, America’s largest paramilitary organization, is affected when the group’s leadership employs three tactics: showcasing their ideological zeal through armed standoffs with the government, membership discounts, and sports sponsorships. Using a variant of the synthetic control method, he finds that standoffs increase new memberships by 150 percent, discounts increase new memberships by over 60 percent, and sports sponsorships decrease new memberships. Membership is less responsive in counties with higher income inequality, but is more responsive in politically conservative counties. The findings provide new insights into ways extremist groups attract potential recruits.

Domestic and foreign violent extremist organizations, or terrorist groups, have caused a greater amount of harm with chemical agents than with biological or radiological weapons. The United States capacity and capability to identify, prevent, counter, and respond adequately to chemical threats is established by the strategies, policies, and laws enacted across multiple levels of government. While the number of chemical terrorism incidents has risen and fallen over time, there is no empirical or analytical indication that the threat is disappearing. This report comes at a time when the nation's highest-level strategies have shifted from focusing primarily on violent extremist organizations to focusing more on Great Power Competition. This shift in relative perceived threat and consequent prioritization will impact efforts against chemical terrorism, and in turn, affect funding priorities. Revised risk assessments are needed to reprioritize risks guided by new strategies, so that strategy-aligned budgets can be created. The report recommends weapons of mass destruction budgets be aligned with evolving priorities and incentivize activities that transition promising research to operations.
