India doesn't any friends in the region so long as it has Washington's backing. Just look at the assassination of Sikh leader in Canada. India literally has a free hand to do whatever it wants because Washington needs India to contain China. Can you imagine China sending MSS agents to assassinate Uighur and Tibetan activists in the US or Canada? Washington would probably levy tons of sanctions afterward, if not worse. That's the principle of double standards in international politics. It is all decided by big guys and the geopolitical landscape.A rapist Hindu-nationalist regime dominating? Are you talking about in a sexual way?
A nationalist government isn't going to make many friends locally. Just look at all the push back against China in East Asia for the perceived aggressions.
And yes, India is a rapist superpower. It is one of the few countries where men can easily get away with rape, whilst the majority of the society turn a blind eye on sexual, caste, and religious violence. If the India were to dominate Asia, the same kind of barbarity would be imposed on India's neighbors. So never underestimate the threat India brings. It is not only traditional material power, but also how high-caste Hindu men see the world through their own imaged power dynamics.
