"The previous theory, which clarified the law of the development of human history from the point of view of the materialist outlook on history, related the formation of nations to the emergence and development of capitalism and predicted that the nation itself would gradually disappear with the liquidation of the capitalist system and with progress in the building of socialism and communism, in all countries. In the historical conditions of the age when the motive force of the revolution was not prepared in each country and nation and when the need to strengthen the international solidarity of the working class in the struggle against capitalism and imperialism was the basic problem, the previous theory was unable to raise the question of keeping the Juche character and national character of the socialist cause to be carried out. The previous theory's proposition that the working class has no motherland can be viewed as reflecting the requirement for strengthening international working-class unity and solidarity which were urgent for the socialist movement of the period as well as the need for overcoming opportunism which spread bourgeois nationalism in the working-class movement and the socialist movement." --- Leader KIM JONG IL "On Preserving the Juche Character and National Character of the Revolution and Construction" (June 19th, 2007)
