In a recent interview Seymour Hersh spoke (@2:50m) about U.S. military operations in Africa:

„We have a big special forces community that are active particular in Africa, in lot of places. I think the public knows very little about it. I don‘t think my president has been briefed on it. I think he isn‘t interested in it or just doesn‘t know about it. I know there is concern among some people in the military, high up in the military, in the government, in Washington: ‚What are these guys doing? Who is in control?‘ There is a lack of control among the special forces. Many of them are driven with the idea that they are in a crusade. That they are the Knights of Malta fighting the infidels in the 14th century or 13th century. I mean that‘s really crazy stuff. So when I hear in the military, what the special operations command says about Mali: ‚Here is what happened when four guys died and how.‘ I am sorry but I think there is much more to the story, there is much more to our presence there, but it is very hard to get that stuff.“
