I think the Soviets wrote the handbook NK uses.
He is not only a product of the inhumane ideology that drove the USSR, he embodies it. You can see it in his disregard of human life, in his placing of the crushing powers of the state over individual freedoms.
It's also the ideology of the PRC, and NK indeed. It's simple: communism needs dictatorship to survive and it attracts and enables the most powerful dictators: madmen and psychopaths.
It wouldn't be much of a stretch to say that the original commenter was trying to associate Putin's actions with those of North Korea and therefore the Soviet Union.
