they did this in the name of trying to overthrow the british imperialists and trying to gain the japanese support while the japanese war criminals wanted them for re-inforcing their Asian invasion
The japanese was also thinking by conquering india. they could fetch large amount of food and resources from the sub-continent
I remembered seeing some photos on pdf where indian soldiers appearing on the Mainland or in the backgrounds where some Chinese buildings were there
even though the indians are not near the japanese war crimes on us, as I have pointed out they have never been showing they are our friends - their illegal occupation of Zangnan 藏南;representation of their despicable judge on the international far east war crimes tribunal who had absolved the japanese criminals of all war crimes, dollar lama issues, taking part in scs oil drilling, disallowing us to approach their territory in search of MH370 etc they almost sit on the opposite side of the fence all the tme!
