>Bulgaria is not a war party, Starlink is [...] it doesn't cover special military protection or war involvement
Huh? So by your logic, if Russian soldiers in fatigues are shooting up a Ukrainian Roshen candy shop in Sofia Bulgaria, it's no the job of the Bulgarian state to intervene and fire back at those Russian soldiers on Bulgarian soil or arrest them, because according to you it's just a war dispute between Russia and Ukraine that doesn't concern Bulgaria and it's government law enforcement?
In the end it'll be up to the courts to decide if the incident on Starlink is an act of war not covered by insurance and law enforcement, or vandalism that falls under the responsibility of the Bulgarian state law enforcement, but you're logic is pure comedic FUBAR.
A more appropriate comparison would be if Russian agents assassinated a local industrialist.
And, well, would you expect the state to proactively assign military protection details to such people?
No. They would have their own body guards, and maybe a police protection if needed. But not army.
The spy and counterspy agency would probably investigate, but they are not going to post a flak cannon next to each Starlink base station.
