Map of 2,872 terrorist incidents in thecontiguous United States from 1970 to 2017. KEY: Orange: 2001–2017; Green: 1970–2000Terrorism deaths in the United States
In theUnited States, terrorism is defined as the systematic orthreatened use of violence in order to create a climate offear with the goal of intimidating a population or government and thereby spurringpolitical,religious, orideological change.[1][2] This article serves as a list and a compilation of acts ofterrorism, attempts to commit acts of terrorism, and other such items which pertain to terrorist activities which are engaged in bynon-state actors orspies who are acting in the interests ofstate actors or persons who are acting without the approval of foreign governments within the domestic borders of the United States.
In 2019, Matthew Alcoke, Deputy Assistant Director of theFBI Counterterrorism Division, defined domestic terrorists as "individuals who commit violent criminal acts in furtherance of ideological goals stemming from domestic issues."[14] Although acts of violence by domestic extremists meet the definition, no US criminal charge fordomestic terror exists. Rather, the phrase is anFBI investigative category used to classify four types of extremism: "racially motivated violent extremism, anti-government/anti-authority extremism,animal rights/environmental extremism, andabortion extremism."[14] A 2017 report by theU.S. Government Accountability Office found that out of the 85 deadly extremist incidents which had occurred sinceSeptember 11, 2001,white supremacist extremist groups were responsible for 73%, while radicalIslamist extremists were responsible for 27%. The total number of deaths caused by each group was about the same. However, 41% of the deaths that were attributable to radical Islamists all occurred in a single event — the 2016Orlando nightclub shooting in which 49 people were killed by a lone gunman. No deaths were attributed toleft-wing groups.[15][16] A 2017 report byType Media Center andThe Center for Investigative Reporting analyzed a list of the terrorist incidents which occurred in the US between 2008 and 2016 and included the2014 killings of NYPD officers and the2016 shooting of Dallas police officers (a total of seven deaths saying that they could "plausibly be attributed to a perpetrator with such sympathies").[17]
In 2018, most ideologically motivated murders in the United States of America were linked toright-wing extremism.[18] As of 2020, right-wing extremist terrorism accounted for the majority of terrorist attacks and plots in the US[19][20] and has killed more people in the continental United States since the September 11 attacks than Islamic terrorism.[21] TheUnited States Department of Homeland Security reported in October 2020 that white supremacists posed the top domestic terrorism threat, which FBI directorChristopher Wray confirmed in March 2021, noting that the bureau had elevated the threat to the same level asISIS.[22][23][24]
115far-right inspired terrorist incidents. 35% of these incidents were foiled (this number means that no terrorist attacks occurred) and 29% of them resulted in fatalities. These incidents caused79 deaths.
63Islamist inspired terrorist incidents. 76% of these terrorist incidents were foiled (this number means that no terrorist attacks occurred) and 13% of them resulted in fatalities. These incidents caused90 deaths.
19far-left inspired terrorist incidents. 20% of these terrorist incidents were foiled (this number means that no terrorist attacks occurred) and 10% of them resulted in fatalities. Two of these incidents were described as "plausibly" attributed to a perpetrator with left-wing sympathies and caused7 deaths. These are not included in the official government database.[15]
According to a report which is based onJustice Department figures which were released by the U.S. government in January 2018, about three out of four people who were convicted on charges ofinternational terrorism between September 11, 2001, to December 31, 2016, were foreign-born. According to the Justice Department, 549 people were convicted on charges of international terrorism, including 254 people who were citizens of other countries, 148 people were naturalized citizens and 148 people werenatural-born-citizens.[29] In a speech made before a joint session of Congress on February 28, 2017, PresidentDonald Trump incorrectly attributed these findings todomestic terrorism; in actuality, the findings were based on cases in which international terrorists may have been brought to the United States for prosecution.[30]
In 2015, the Triangle Center on Terrorism and Homeland Security and the Police Executive Research Forum conducted a nationwide survey of 382 police and sheriff departments. Nearly 74% of respondents stated that anti-government violence was their top concern with regard to threats from violent extremists, while about 39% of respondents stated that "Al Qaeda-inspired" violence was their top concern.[31][32]
For the past decade, the national conversation on terrorism has largely focused on Islamic extremist acts, however, law enforcement groups have made it clear that Muslim extremists perpetrate a minute percentage of the ideologically based terrorist attacks which are perpetrated in the United States.[33] Since November 9, 2001, only about 9 American Muslims per year have taken part in terrorist plots in the United States, in total, 20 incidents resulted in about 50 deaths. A 2012 study showed that in about the same time period right-wing extremists were responsible for about 337 attacks per year, in total, they killed more than 5 times the number of people killed by Muslims in the United States.[34]
TheNational Consortium for the Study of Terrorism and Responses to Terrorism maintainsProfiles of Individual Radicalization in the United States, a database which contains over 1,800 profiles of individuals who have been radicalized by ideologies since 1948.[35] The database shows that from 1948 through 2016, 40.0% of identified extremists were far-right, 24.5% of identified extremists were Islamist and 17.4% of identified extremists were far-left, while 18.2% of identified extremists were "single issue" individuals.[36]
In May 2019 and for the first time in its history, the FBI identifiedfringeconspiracy theories as a potential source of domestic terrorism, it specifically citedQAnon.[37]
A June 2020 study of domestic terrorist incidents by theCenter for Strategic and International Studies (CSIS) reported that during the previous 25 years, the majority of attacks and plots were perpetrated and hatched by far-right attackers. This trend has accelerated in recent years, with this sector being responsible for about 66% of all of the attacks and plots which were perpetrated in 2019, and it was also responsible for 90% of all of those attacks which were perpetrated in 2020. The next most potentially dangerous group has been "religious extremists", the majority "Salafi jihadists inspired by the Islamic State and al-Qaeda", while the number planned by the far left has reduced to a minute fraction since the mid-2000s.[38][39]
In October 2020, the Department of Homeland Security released theHomeland Threat Assessment, a report detailing various domestic threats toUS national security. It states that, out of all domestic terror attacks resulting in lethal threats to life between 2018 and 2019, "WSEs [white supremacist extremists] conducted half of all lethal attacks (8 of 16), resulting in the majority of deaths (39 of 48)".[40]
Soon after theassassination of Charlie Kirk, U.S. President Trump claimed that "the radicals on the left are the problem" with political violence.[41] Opinion editors,[42] as well as both far-right commentators[43] and Trump critics,[44] have compared Charlie Kirk's killing to theReichstag fire—the 1933 arson of theGerman parliament building that Hitler used as apretext to suspend civil liberties and prosecute political opposition[44]—some calling Kirk's killing Trump's "Reichstag fire moment".[42]How Democracies Die author, professorSteven Levitsky, said that exploiting Charlie Kirk's killing to justify unleashing attacks on critics is "page one of theauthoritarian playbook".[45]
