Why would Balkan tax payers pay to secure foreign corporation? Especially if that corporation is involved in a war they don't care which makes it a legitimate military target.
Because that foreign corporation presumedly purchased the local property, pays local taxes on it, and probably employs some local people. Or are you claiming that the property of anyone foreign anywhere is up for grabs because they're foreign?
You're seriously asking why the state would enforce property rights?
>Why would Balkan tax payers pay to secure foreign corporation?
Because foreign corporations operating in the Balkans pay taxes in the balkans, own property/real estate on Balkan soil on which their business operates, and employ workers in the balkans.
