United States: Domestic violent extremism on the rise

By Piotr Bąkowski

n recent years, the United States (US) has witnessed a growing number of terrorist attacks by domestic violent extremists. Many incidents at large-scale demonstrations across the country have increased the visibility of the problem and provoked strong reactions among civilians, law enforcement and policy-makers alike. When on 6 January 2021 a crowd of supporters of the then US President, Donald Trump, broke into the US Capitol while Congress was certifying the results of the 2020 presidential election, the issue of domestic violent extremism was thrust beyond US borders and into the international spotlight. Various US government agencies have consistently assessed domestic violent extremism as a significant threat. Although for counter-terrorism purposes extremists fall under a number of categories of a general nature, the threat they pose has become more decentralised and diverse over time. That said, racially and ethnically motivated violent extremists have been responsible for the most lethal acts of violence. After 11 September 2001, the focus of US counter-terrorism efforts shifted to international from domestic terrorism. US law does define domestic terrorism but does not qualify it as a criminal offence entailing indictment. Domestic extremist groups cannot be designated as terrorist organisations, and getting clearance to conduct investigations against them is more complicated than for their foreign counterparts. The assault on the Capitol led to a significant shift in counter-terrorism priorities, however, triggering the largest-scale investigation in US law enforcement history thus far, but also a comprehensive overhaul of government policies. Consequently, 2021 saw the adoption of the first national strategy specifically dedicated to domestic terrorism. The mutual commitment of the US and the European Union (EU) to combating violent extremism has resulted in fruitful exchanges among policy-makers, researchers and frontline practitioners. Nonetheless, efforts to establish a unified regulatory framework for addressing online extremist content have faced challenges due to differing perspectives on key issues such as the limits of free speech and government intervention.
