where and who were they care to elaborate ?
SCB had no success with the Germans as Hitler shied away from supporting a non white.
Japs from their success in Malaya against the British force - viewed the British and Indian soldiers to be inferior , fit for fighting a psychological warfare and provide free labour.
INA was under Japanese command, this compromise didn't work as there was constant disagreement between SCB and Japanese command e.g for SCB - priority was the liberation (Japanese Invasion) of British India , Tokyo's top priority was the Pacific Operation - British India operation was in the back burner .
Imperial Japan had no intention in 'liberating' (invading) British India for SCB - Japanese operation was confine to securing strategic areas in British India for the defence of Burma (Myanmar)
Read some history ignoramus.
Subhash Chandra Bose had limited success in Germany, and raised Frei Indische legion there, and contrary to what you are espousing, he was treated well in Germany and even married there. You are forgetting that Hitler was a race nationalist and for him Indian race did not existed and he and Himmler prescribed to Aryan-Invasion theory religiously and Indians according to them consisted of high caste descendants of Aryans and untermensch dravidians, which actually makes adoration of Hitler by low caste dravidians like Vanniyars ,as visible in this thread, so much hilarious as ,if he had won, he would have treated those low caste vanniyars as piece of turds who are polluting this planet. (not that he think highly of Indians in general ,who according to him were mongralized, but low caste dravidians in his race hierarchy were pure untermensch)
The reason Bose shifted to Japan was for these reasons.
1. Rommel was defeated in 1942 killing any chance of Germany's advance onto India for time being.
2. Japanese won Singapore where enough Indian PoWs were captured that a viable army could be formed from them.
3. In Axis power negotiations, 70 degree east was initially envisioned as rough border of German and Japanese sphere of influence and later negotiations changed border of possible spheres of influence to run along Western border of British India and Afghanistan. In these negotiations, India was allocated as a nation under Japanese sphere of influence.
4. According to understanding between Germany and Japan in 1942, whole world was divided into two theaters for German and Japanese military with both military not undertaking operations in each-other's theater for sake of having clarity in objectives. India in this scheme fell into Japanese sphere of influence hence it was Japanese military which was to undertake offensive in India.
Thus Subhash chandra bose had no reason to stay in Germany after that.
