In the treatise, he noted that under the banner of Songun (military-first) leader Kim Jong Il protected the dignity and supreme interests of the country and the nation in reliance on powerful arms and glorified the Democratic People's Republic of Korea as an invincible socialist power.

Kim Jong Il's inspection of the Seoul Ryu Kyong Su 105 Guards Tanks Division of the Korean People's Army (KPA) on Aug. 25, Juche 49 (1960) was a historic event, through which he clarified the idea that the revolution starts, advances and is accomplished by dint of arms.

He showed his distinguished political and military ability while inspecting many KPA units.

In the 1990s, Kim Jong Il defined the Songun politics as the basic mode of politics under socialism and pursued it to reliably defend the country and socialism while turning the DPRK into a politico-ideological and military power.

He also strengthened the KPA into the main force of the revolution intensely loyal to the guidance of the Workers' Party of Korea and achieved the harmonious whole of the Party and the army and the great unity between the servicepersons and the civilians.

The socialist cause of Juche is sure to be accomplished thanks to the great feats of Kim Jong Il, who gave top priority to the military affairs, trained the KPA to be the standard-bearer of the Songun revolution and led the revolution and construction to victory under the banner of Songun.
