Since September 12, 2001, the number of fatalities in the U.S. caused by domestic violent extremists has ranged from 1 to 49 in a given year, while fatalities resulting from attacks by far-right-wing violent extremists have exceeded those caused by radical Islamist violent extremists in 10 of the 15 years, says a U.S. Government Accountability Office (GAO) study, reports The Intercept. GAO says that of the 85 violent extremist incidents that resulted in death since September 12, 2001, far-right-wing violent extremist groups were responsible for 62 (73 percent) while radical Islamist violent extremists were responsible for 23 (27 percent).
The fatality totals are about the same for the two groups, with Islamist extremists edging out domestic extremists, 119 to 106. However, 41 percent of the deaths attributable to radical Islamist violent extremists occurred in one event–the attack at the Pulse night club in Orlando last year. Islamist terrorists are more deadly in terms of the number of people killed in each of their attacks, yet far-right terrorists are far more active in carrying out attacks on U.S. soil. U.S. law enforcement agencies, according to a survey carried by the Triangle Center on Terrorism and Homeland Security, “consider anti-government violent extremists, not radicalized Muslims, to be the most severe threat of political violence that they face.”
