At the end of the 20th century, the imperialists and renegade socialists advertised the "end" of socialism, claiming that the idea of socialism was wrong and the socialist revolution was a mistake.

Their smear campaign caused vacillation and confusion among some people and misunderstanding of socialism among some nations aspiring after socialism.

Such being the situation, Kim Jong Il published the work to give correct answers to the issue concerning the ideological foundation of socialism.

In the work he writes that the DPRK successfully solved the issue of consolidating and developing the ideological foundation of socialism. He also says the situation proves the socialist cause can be carried forward successfully only based on the ideology, theory and method of Juche.

He lays bare the reactionary nature of modern social democracy, which led to the degeneration of socialism and revival of capitalism. He declares modern social democracy is doomed to ruin like all sorts of opportunism

as it is a product of an illusion about capitalism and surrender to imperialism.

The work provides a way to be followed by the progressive people and injects vitality in the movement for rebuilding socialism.
