Okay Chaps,
Throw a Dyce probably should have been a little more tactful in his posts. But he has a genuine concern and there is a problem with fast jets infringing the Aberdeen zone.
When civil airliners are operating in class G they are fair game (if that is what you think) because they are operating in the open FIR and everyone is entitled to be there. When they are operating in Controlled Airspace they are entitled to expect that aircraft that are not under the control of the appropriate control agency will not be endangering their flight.
Speaking as a controller who has experience in both the military and civil worlds, Infringments of CAS are the biggest danger at the moment for NATS and civil airline operators (Yes really). A fast jet coming into conflict in the control zone becomes a very difficult aircraft to avoid and please don't say that you are able to avoid the civil aircraft. The stats show that see and avoid is not a particularly safe resolution
TCAS and aircraft performance in these situations gives a very bare separation when trying to avoid a fast jet with high amounts of energy.
