Now they are increasingly talking about the need for a "new oprichnina" to fight against the "fifth column" and corruption. They say that the Russian "elites" are so amazed by theft and betrayal, and the metastases of treason have penetrated so deeply into all law enforcement agencies that, following the example of Ivan the Terrible, it is necessary to create a completely new power structure, accountable only to the head of state. That's just how this "experiment" ended five centuries ago? What does the experience of history teach us? Was the oprichnina a salvation for Russia - or, conversely, ruined the Moscow kingdom? Is it possible to establish the rule of law by lawless methods? And what price does tyranny and repression have to pay?
