So a bomb threat made against an aircraft full of passengers is not terrorism?
ATC can piss off in this situation. Any viable threat information against an aircraft will come from the company itself, not ATC.
If the MiG was visible, now you are out of luck as you must comply with the Pilot(not ATC), as per any manual I have ever read.
A bit more experience and the crew could have faked any number of emergencies to descend into their destination airport, especially considering it was the closest. Now there may not have been enough time to get a solid grasp of this situation, but there were still a lot of other possibilities to consider.
