In the United States a common definition of terrorism is the systematic or threatened use of violence to create a general climate of fear to intimidate a population or government and thereby effect political, religious, or ideological change.[1][2] This article serves as a list and compilation of acts of terrorism, attempts of terrorism, and other such items pertaining to terrorist activities within the domestic borders of the United States by non-state actors or spies acting in the interests of or persons acting without approval of state actors.

According to a 2017 report by the U.S. Government Accountability Office, "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 total number of fatalities is about the same for far right wing violent extremists and radical Islamist violent extremists over the approximately 15-year period (106 and 94, respectively). However, 52 percent of the deaths attributable to radical Islamist violent extremists occurred in a single event—an attack on the Pulse nightclub in Orlando, Florida in 2016."[3][4]

In 2018, most ideologically motivated murders were linked to right-wing extremism.[5]

Recent trends[edit]

A 2017 report by The Nation Institute and Center for Investigative Reporting looked at the terrorist incidents in the US between 2008 and 2016.[8] It found:[9]

  • 115 right-wing inspired terror incidents. 35% of these were foiled (meaning no attack happened) and 29% resulted in fatalities. These terror incidents caused 79 deaths.
  • 63 Islamist inspired terror incidents. 76% of these were foiled (meaning no attack happened) and 13% resulted in fatalities. These terror incidents caused 90 deaths.
  • 19 incidents inspired by left-wing ideologies (including eco-terrorism). 20% of these were foiled (meaning no attack happened) and 10% resulted in fatalities. These terror incidents caused 7 deaths.

According to a report based on Justice Department figures released by the U.S. government January 2018, about three out of four people convicted on charges of international terrorism between September 11, 2001 to December 31, 2016, were foreign-born. According to the Justice Department, 549 were convicted for international terrorism including 254 who were citizens of another country, 148 were naturalized citizens and 148 were natural-born-citizens.[10] In a speech before a joint session of Congress on February 28, 2017, President Donald Trump incorrectly attributed these findings to domestic terrorism, rather than to cases in which international terrorists may have been brought to the United States for prosecution.[11]

The Triangle Center on Terrorism and Homeland Security and the Police Executive Research Forum conducted a 2015 survey of 382 police and sheriff departments nationwide. Nearly 74% of respondents stated that anti-government violence was their top concern regarding threats from violent extremism, while about 39% stated "Al Qaeda-inspired" violence was their top concern.[12][13]

The National Consortium for the Study of Terrorism and Responses to Terrorism maintains Profiles of Individual Radicalization in the United States, a database containing over 1,800 profiles of individuals radicalized by ideologies since 1948.[14] The database shows that from 1948 through 2016, 40.0% of identified extremists were far-right, 24.5% were Islamist and 17.4% were far-left, while 18.2% were "single issue" individuals.[15]
