On 19 August 1945 in the PPKI session, two PPKI members Abikoesno Tjokrosoejoso and Oto Iskandar di Nata proposed the raising of a national defense force for the new republic. However, the proposal was rejected on the grounds that it could provoke clashes with the occupying Imperial Japanese Army who were still armed and invited the intervention of Allied troops who would disarm the Japanese army after the Surrender of Japan. The 344,000 Japanese troops throughout Indonesia were mentally devastated by losing the war. With an unstable mental state they were given the task by the allied forces to maintain security in Indonesia until their arrival in the lands of the new republic.
