There has been a significant rise in the number of domestic terrorist attacks and plots at demonstrations in the United States, according to new CSIS data. The result is escalating violence in U.S. cities between extremists from opposing sides, a major break from historical trends. In 2021, over half of all domestic terrorist incidents occurred in the context of metropolitan demonstrations. In addition, the most frequent targets of attacks were government, military, and law enforcement agencies, who are increasingly at the center of domestic terrorism by extremists of all ideologies.
