When he convened a meeting of commanding officers of the Korean People's Revolutionary Army (KPRA) in May Juche 34 (1945), he discussed the operational issue related to the liberation of the country. He stressed the need for all the Korean revolutionaries to firmly maintain the firm Juche-oriented stand that they should liberate the country by their own efforts, strengthen the political and military might of the KPRA in every way and prepare the resistance organizations in the homeland well so that they would launch all-people resistance in support of the KPRA's liberation operation.

At a meeting of the KPRA military and political cadres held after the meeting, he set forth the revolutionary slogan "Every Effort for the Final Victory of the Great Anti-Japanese War!" to arouse all the KPRA commanding officers and members and all the anti-Japanese patriotic forces of the country to the final sacred war for national liberation.

The President finally completed the plan for the final offensive operation for national liberation, which he had prepared with much care, and made it public at a meeting of KPRA military and political cadres on July 30, 1945.

The strategic intention of the plan was to defeat the Japanese imperialist aggressors and liberate the country through an active offensive operation of the KPRA combined with all-people resistance.

As the Juche-oriented revolutionary forces of the Korean people were fully prepared for the final decisive battle against the Japanese imperialists, the President ordered all the units of the KPRA to launch a general offensive for national liberation on August 9, 1945.

The Japanese imperialists, who were defeated by the fierce attack of the KPRA and the positive all-people resistance, declared unconditional surrender on August 15, one week after the start of the final offensive operation.

The cause of national liberation, which the Korean people had desired so ardently, was successfully accomplished under the leadership of the President who defeated the Japanese imperialists through all-people resistance and led the anti-Japanese revolutionary struggle to victory under the uplifted banner of independent national liberation.
