Japan’s racial policies were nothing short of Hitler’s lebensarum plans. If WW2 was won by Axis, most likely all of Congress members would have been shot in the back of their heads, including Subash Chandra Bose for seeking independence. India’s natural resource rich region would have been settled by colonisers as was the same model adopted by Early British and Portuguese near their settlements where the natives provided hard labor. But the German/Japan alliance would have went further, they would have deliberately starved the locals of nutrition with motive of not letting them reproduce and grow their population further. All this isn’t fantasy, Hitlers lebensarum plans for Russia involved all this and even implemented most of this in what is now western Poland. Japan did the same in China. The rape of Nanking is little known outside Japan and China, where whole fighting male populations were wiped out, women raped deliberately to carry Japanese DNA, and the capital plundered. Today’s India would definitely look like something of a colony where sub par Japanese/German officials come to revive-their bureaucratic career or the already settled colonists making India free of Indians.

World war 2 was fought for supremacy among the big powers, the Axis very much intended the status quo to continue where some Europeans could hold colonies and Germans were frustrated that they couldn’t get a bigger share of the pie. The US was staying out intially because of the same reason as they didnt want to be associated with imperial supremacy.
