Majority Investigative Report: Homegrown Terrorism: The Threat to Military Communities Inside The United States [open pdf - 409KB]
"More than 2.3 million Americans in the military have volunteered to go into harm's way overseas to combat terrorists since 9/11. But these heroes 'who shall have borne the battle,' as President Lincoln called war veterans, also have been in danger here at home -- where they should be safe and secure. The threat is real. The Department of Defense considers the U.S. Homeland the most dangerous place for a G.I. outside of foreign warzones -- and the top threat they face here is from violent Islamist extremists. […] A significant and growing number of military personnel, such as alleged Fort Hood mass murderer Army Maj. Nidal Malik Hasan, pose a serious danger to their brothers and sisters in arms who wear the same uniform. At least 33 threats, plots and strikes against U.S. military communities since 9/11 have been part of a surge of homegrown terrorism which Attorney General Eric Holder has said 'keeps me up at night.' After Al Qaeda leader Osama Bin Laden was killed May 1, the Department of Homeland Security, Federal Bureau of Investigation and Defense Intelligence Agency warned thousands of U.S. law enforcement and security agencies about possible retaliatory attacks by Al Qaeda, its allies or unaffiliated homegrown terrorists on our military. Weeks after the Pakistan raid, two radicalized U.S. citizens allegedly plotted to attack military personnel in Seattle. The Majority Staff of the House Committee on Homeland Security has been conducting an investigation, which finds that 70% of the plots against military targets occurred since mid-2009 -- including the two successful homeland attacks since 9/11."
