The immortal famous works have become a powerful ideological weapon which significantly raised the spiritual strength and creative power of the Korean people and served as the most scientific and revolutionary programme of the Juche revolution which put the dignity and power of the Republic on the highest level.

Kim Jong Un declared in his speech delivered at the military parade in celebration of the centenary of the birth of President Kim Il Sung on April 15, Juche 101 (2012) that the long-range strategy and final victory of the Korean revolution depend on advancing straight along the road of independence and socialism.

Some works deal with the idea of discarding dependence on others, realizing the local production of raw and other materials and equipment and fully demonstrating the revolutionary spirit of self-reliance in all sectors and units.

Other works stress the importance of the geological prospecting in strengthening the self-development of the state in every way and developing the economy independently and the tasks for normalizing the fruit production by relying on its own scientific and technological forces and material and technological foundations.

"We Must Consolidate the Might of the Juche-oriented Defence Industry by Applying the Principle of Self-development First" and other works became a militant banner which developed the country's defence industry into a development- and creation-oriented industry, not just copying samples.

Kim Jong Un set a militant slogan in his New Year Address for 2017 and provided in the reports made at the 3rd, 4th and 5th plenary meetings of the 7th Central Committee of the Workers' Party of Korea the guidelines that help advance our revolution along the invariable orbit of prosperity by dint of self-reliance.

The policy speech "On Socialist Construction and the Internal and External Policies of the Government of the Republic at the Present Stage" delivered by him at the 1st Session of the 14th Supreme People's Assembly of the DPRK on April 12, 2019 is an important document which provided the powerful weapon to deal a severe blow to the hostile forces who are attempting to block our advance, and to accelerate socialist construction at the highest speed by our own efforts and on our own way.
