The Department of Homeland Security released a report in 2009 stating that the economic and political climate bears important similarities to the conditions of the early 1990s when right-wing extremism experienced a dramatic resurgence. These conditions, including the public debate around hot-button issues such as immigration, gun control, and abortion, along with the election of the first African-American president, present “unique drivers for right-wing radicalization and recruitment,” the report said.
Homeland Security Secretary Janet Napolitano eventually ordered the report withdrawn because of significant political backlash from mainstream conservatives. But the report, which was originally commissioned by the Bush administration, also found that “lone wolves and small terrorist cells embracing violent rightwing extremist ideology are the most dangerous domestic terrorism threat in the United States.”
A look at terrorist incidents since the Oklahoma City bombing, including both successful and disrupted ideologically-motivated attacks, backs up the conclusions of the DHS report:
Fifty-six percent of domestic terrorist attacks and plots in the U.S. since 1995 have been perpetrated by right-wing extremists, as compared to 30 percent by ecoterrorists and 12 percent by Islamic extremists. Right-wing extremism has been responsible for the greatest number of terrorist incidents in the U.S. in 13 of the 17 years since the Oklahoma City bombing.
