I also find the contrast with Norway's response to the 2011 massacre quite interesting (http://www.theatlanticwire.com/global/2011/07/comparing-how-...).
Brevik was a lone weirdo. He didn't have a base and support in other countries. He didn't have an army of thousands backing him up.
The Norway massacre is dissimilar, but these points here are the same. There is no, and never was a "global terrorist network". That's all fantasy to sell more useless war to american citizens.
But there was and is global co-operation between terrorist groups, which is why sometimes IRA members turn up in Colombia[1], and there is a definite link between global organised crime and terrorism (whether it be ETA buying guns from the mafia or FARC being funded by cocaine exports).
The fantasy really is the belief by many in the US that terrorism equates to a hatred of America, which in reality is not the case.
But there were disparate terrorist organisations that co-operated and co-ordinated. Both with each other and with rogue states.
AFAIK, Brevik co-ordinated only with himself.
