From a technical view it might not even be terrorism.  People that believe in an evil shadow government are not likely to try causing terror in the general public. There could be several other better labels. Irregulars or rebels for war. Saboteurs for those that target opperations and infrastructure.  Assassins for those killing VIPs. I just don't see terrorist as a good label.  Because people that believe in state corruption are going to attack the state and not the people.
