Recent trends

An April 2017 analysis prepared for Congress by the Government Accountability Office found that between September 12, 2001 and December 31, 2016, 73% of violent extremist incidents resulting in deaths were perpetrated by far right wing violent extremist groups, while 27% were perpetrated by radical Islamist violent extremists.

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

• 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. 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.
