Evil India , After independence, RSS, A hindu nationalist organisation wanted to to coup the new Indian Government and create a Hindu dominated Govt. If it happened, India would first and foremost kill or convert all its Muslims and Christians. Sikhs, Buddhists and Jains would be spared since RSS considered them an offshoot of Hinduism but conversions to those religions would be banned.
India would be much stronger Militarily and be an Ally of USA during Cold war, India would also try to annex Nepal, Bhutan and Sri Lanka, Because of their Hindu and Buddhist Populations. Kashmir would be cleansed would have near 100% Hindu Population.
Also India would Not be called India, But it will be called Bharat. Sanskrit will be one of the largest languages in the world as RSS promotes them but they also promote regional Languages
India Or Bharat, will be a staunch supporter or Israel and advise them to do the same thing against the muslims as India did. India will be really aggressive against Pakistan and will control places which they occupied in Pakistan. Such as Lahore
During 1971 war, India will try to annex Bangladesh or parts of the country and will to the same thing to muslims as they did to their own muslims.
In short India world be stronger militarily and would be larger in terms of area, population would be less because of killing the muslims and christians.
India would be A Hindu Saudi Arabia will nukes and a Military strong enough to challenge even USA.
