Analyst's note:  Note that NPR is politically correct and only refers to them as "Extremist" in their headline ... now what does the FBI call them? Given Obama administration efforts to squelch all investigations and prosecutions of Islamic radicals in the U.S., one must wonder.   We certainly wouldn't want any more "work-place violence" ... like Fort Hood .... now would we.

The FBI has conducted more than 100 investigations into suspected Islamic extremists within the military, NPR has learned. About a dozen of those cases are considered serious.

Officials define that as a case requiring a formal investigation to gather information against suspects who appear to have demonstrated a strong intent to attack military targets. This is the first time the figures have been publicly disclosed.

The FBI and Department of Defense call these cases "insider threats." They include not just active and reserve military personnel but also individuals who have access to military facilities such as contractors and close family members with dependent ID cards.

[....] Officials say for many aspiring violent jihadis a military base is seen as fair game for an attack. Al-Qaida's narrative revolves around the idea that America is at war with Islam the world over, and the perception is that the U.S. military is at the forefront of that battle.

[....] "You have to think about how people in the military community aren't just your run-of-the-mill jihadis," Hoffman says. "These are people who have access to guns and to bases and are supposed to have security clearances. This is not the community you want to be radicalizing."
