Are all domestic terrorists being instructed by Al-Qaeda HQ?

Jason Burke (Author) gives expert video advice on: What is Al-Qaeda?; What does Al-Qaeda want?; When was Al-Qaeda formed? and more...

Trying to trace out the exact links between terrorist on the ground and the headquarters is very difficult what you can say is a sliding scale. At one end of the scale there are attacks that are very closely planned, monitored, commissioned by Al-Qaeda hardcore and Al-Qaeda HQ. At the other end of the scale you have attacks that are entirely autonomous, that have no direct, indeed often no indirect link with Osama Bin Laden and the people around him for example. An example of the former, tightly knit control group would be the 1998 bombers in east Africa, the 2001 9-11 bombers, and the example of the latter, those with no link to the Al-Qaeda hardcore, would be the Madrid bombings in, 2004. And then you can have pretty much, any permutation in between as well.
