Before last week's bombing attack in Boston, there was a growing anxiety in the United States not only about homegrown violent Islamic extremism, but -- especially after Nidal Hasan killed 13 fellow soldiers at Fort Hood, and then further after Eric Harroun was accused of fighting alongside a terrorist group in Syria last month -- about the specific and particularly frightening prospect of such extremism developing among members or trainees of the U.S. military. It's an understandable anxiety, and it may again be vindicated. But there's meanwhile a more worrying danger: that right-wing extremists who have served in the U.S. military will use their training in carrying out terrorist violence.
Right-wing extremists are more likely than violent Islamist extremists--or, as they are sometimes called, jihadists--to have military experience. They are also better armed, and are responsible for more incidents. The past two decades have seen multiple attacks from right-wing extremist veterans, from Wade Michael Page, who trained at Fort Bragg, to the group of former and active-duty soldiers in Georgia, who collected weapons to carry out a plan to assassinate President Obama. In 2011, Kevin Harpham, who had served in the army, placed a bomb along the route of a Martin Luther King Jr. Day parade. During the 1990s, violent extremism in the militia movement and other right-wing movements relied heavily upon those who served in the military. Timothy McVeigh, the perpetrator of the most deadly terrorist attack on American soil before 9/11, was a military veteran whose libertarian views were also heavily influenced by a novel by a former American Nazi Party official. Eric Rudolph, the anti-abortion extremist who bombed the 1996 Olympics, had also enlisted in the army.
Daryl Johnson, former senior domestic terrorism analyst at the Department of Homeland Security, noted the important relationship between the military and violent right-wing extremism in his book Right Wing Resurgence. He writes that right-wing extremists "target law enforcement and military personnel for their training experience (particularly weapons and explosives training), their disciplined way of life, leadership skills, and access to weapons, equipment, and sensitive information." Johnson further notes that a government survey of 17,080 soldiers found that 3.5 percent of them had been contacted in order to recruit them into an extremist organization and that 7.1 percent said they knew another soldier who they believed to be part of an extremist organization.
The New America Foundation's dataset on homegrown extremists offers a platform to quantitatively compare the threat from military-trained right-wing and jihadist extremists, and to evaluate the significance of the threat from each form of extremism. The dataset includes those extremists indicted or involved in violent activities since 2001. According to the dataset, 13 jihadist and Al Qaeda-linked homegrown extremists served in the US military, and they account for about six percent of jihadist extremists listed in the database. These jihadists do appear to be more dangerous than jihadists who have not served in the military. They are more likely to acquire arms on their own, for example. Furthermore, about twenty-five percent of those who served in the military were involved in violent incidents compared to six percent of all jihadist extremists in the dataset. In terms of raw numbers, the threat of jihadist extremists with experience serving in the US military appears to have held steady or possibly to have declined since 9/11. Slightly over half of the cases involved indictments or incidents prior to 2005, though five cases since 2008 suggest a continued risk.
