If ATC tried to tell me to divert somewhere twice as far away as my destination because of an unsubstantiated bomb theat I'd be highly sceptical of their motives, especially if that state were a known rogue like Belarus. Genuine escorting fighters don't get aggressive, standing on and saying Vilnius was much closer - I'm going there would at least allow an assessment of the situatiuon by causing the authority to declare its intentions, either by letting you go as they must, or by issuing a threat if you don't comply. Upon a threat at that point I would comply, but also consider a broadcast on 121.5 and dialling 7500.
