Kim Jong Il wrote that “introducing individualism into socialism, which is based on collectivism, is tantamount to taking poison.” For this reason, he concluded that “Libertarianism is like an invisible moth gnawing away at the people’s political integrity,” meaning libertarianism is the source of the corruption of socialist ideology which he warned against: “The degeneration of socialism begins with the degeneration of socialist ideology, and the disintegration of the ideological front leads to the disintegration of all fronts of socialism, and in the end to the total collapse of socialism.”
