In particular, he set an excellent example for the national liberation movement in colonial countries.

In the first half of the 20th century when Korea was reduced into a colony and deprived of its history, culture and spoken and written language by the Japanese imperialists, he struck out a new path of liberating the country by the Korean nation itself.

He founded the Juche idea, a man-centered philosophical idea, for the first time in the history of human thought and clarified the truth of revolutionary struggle that the people in colonial countries should achieve the national liberation by their own efforts. His idea that the revolution of one's own country should be made by one's own efforts and imperialism should be defeated through an organized armed struggle in reliance on the strength of the popular masses was a unique one that can not be found in human history and preceding theories.

The creation of the great Juche idea and the line of organized armed struggle opened up a new era in the history of national liberation movement in colonial countries which had been conducted in the way of petition, demonstration, uprising and riot.

On August 15, Juche 34 (1945), the President liberated Korea from Japan's colonial rule with armed struggle. It proved the fact that organized armed struggle is the most powerful method and the highest-level form of struggle for smashing the imperialists' counterrevolutionary violence by one's own efforts to win in the national liberation revolution.

In January 1968 after the lapse of 20-odd years since then, a world culture meeting took place in Havana with the attendance of delegates from 70 countries. At the meeting, "The Korean people's anti-Japanese armed struggle launched under the guidance of Comrade Kim Il Sung", a document dealing with the strategy and tactics in the period of the anti-Japanese armed struggle, was adopted as its document.

This was clear evidence of the world people's recognition and admiration for the undying feats of the President who achieved the national liberation under the banner of independence.
