In light of recent reporting addressing the prevalence of right-wing extremism in Germany’s top special operations unit, the Kommando Spezialkrafte (KSK), it is useful to examine the radicalization profiles of individuals in the United States. While not framed for comparison here, the discussion of individual extremism in the U.S. does offer value as various online-derived extremist movements gain more notoriety.

Indeed, last year, the FBI refocused its efforts on so-called “home-grown” domestic violent extremists. It noted that domestic terrorism cases relate to a range of different ideologies in the form of “racially motivated extremism, anti-government attacks, animal-rights related attacks, anti-abortion attacks,” and others.

One timely and relevant example can be found in the so-called Boogaloo movement, a right-wing extremist movement recently cited by an Air Force sergeant after his late May murder of two officers in Santa Cruz County, California. The Boogaloo movement and the specifics surrounding the online radicalization of the accused present a compelling and fascinating narrative that led a well-trained service member to commit murder.

However, the scope of this article does not seek to explore specific radicalization instances of individuals. It will instead share valuable research that provides greater context for our understanding of individual extremism in the U.S. writ large. Indeed, research from the University of Maryland’s Center for the Study of Terrorism and Responses to Terrorism (START) offers the reader such context in the form of a database profiling 2,226 extremists who radicalized to both violent and non-violent extremism from 1948 to 2018.
