In the work, the leader gave a scientific explanation of the main reason for the collapse of socialism in some countries and indicated ways for successful socialist construction.

He also expounded ideas and theories on building up the driving force of revolution, holding fast to the revolutionary principles and maintaining independence. He said it is the general line of socialist construction to vigorously carry on the ideological, technical and cultural revolutions and strengthen the people's power.

Kim Jong Il performed great exploits in the effort to accomplish the cause of the popular masses' independence.

He made it clear that the cause of the popular masses' independence can be advanced and won by the core and principal role of the revolutionary army.

He put forward the Songun (military-first) revolutionary line based on the unique theory that the army precisely means the party, state and people, making it possible for the army and the people to successfully advance the socialist cause based on the scientific and revolutionary idea.

He created a new history of strengthening the driving force of revolution with the army as the mainstay.

It is the truth acquired by him that the most revolutionary and powerful force is the army in the present society and that when the army and people achieve unity in ideology and working spirit, their strength will be increased considerably.

The DPRK has achieved single-minded unity around the headquarters of revolution on the basis of the Songun idea, fully demonstrating the great political and ideological might of the country and making tremendous achievements in the building of a thriving nation.

All the Korean people are determined to defend the feats the leader performed for the cause of the popular masses' independence and socialism and glorify a new century of the Juche era as one of prosperity under the leadership of the dear respected Kim Jong Un.
