Since the fall of communism in 1989, Bulgarian society has refrained from calling the communist elite and its collaborators to account for the sake of preserving peace. This has allowed for the rise of an extremely powerful mafia, which poses a threat to society as a whole.
The blogger Vesselin Kadimirov comments in the Bulgarian online publication Svobodata (February 14):
“Recently, all observers have reached the same conclusion: Bulgaria is changing from a state with its own mafia into a mafia with its own state…. The executive and legislative have turned into a lucrative monopolist business. The judiciary is independent only to the extent that no one can force it to condemn someone who pays well.
“The borderline between police and organized crime has become blurred – gangsters work for the secret services and ministers pass on business deals among gangsters…. The mafia wants to regain control of its state. Therefore, I believe the time has come for society to renege on its part of the deal…. Twenty years of impunity is a high enough price for peaceful transformation.”

Prior to communism, how was Bulgaria governed? In all likelihood, it was a power structure lacking accountability to the common people. So why are we surprised?
Whatever the power structure – there were only two countries in WWII who resisted the Nazi anti-Jewish terror: Bulgaria and Denmark.
