Apparently, Sindhu is the sanskrit word for the Indus river, so the ancient greeks derived the name India from it, and westerners replaced the previous Hindustan with India during the XVIIIth century ^(, this information would need to be verified), which then became the official name when they colonized it in the middle of the XIXth century.
Persians may have influenced the greeks, i.d.k., i’d have to check if Sindhu or India was the persian word as well. And i didn’t know that Iran(sharh) has always been the persian name, while Persia was the latin name of the empire. I’ve probably made many mistakes in this answer, but i hopefully wrote some truths as well.

Is that good or bad ?

Some indians would like such change, others won’t, and others may have preferred an other name, it’s up to them.
To me personally, it sounds more exotic like that(, you don’t know if “Bh” is pronounced differently than “B”, or how the “r” should sound, and even if the “t” should be heard(, i’m french so we strangely have silent letters)), which may translate for them to a stronger feeling of independence/uniqueness/…, which in turn may result for all of us in more diversity(, without disunity if possible).

Will it go in the direction of the advent of the promised utopian communist paradise ? Perhaps. The very obvious goal for everyone is to isolate China, from Russia(, conservatives love Russia because it can be useful against China, just as westerners loved Ukraine more than other countries for the past decades because it could be useful against Russia), from the rest of the world, and particularly South-East Asia if they can, as well as from India/Barhat, perhaps the most important piece. Even if the latter realize its power/independence from the west they may still choose conflict against China, and/or against muslim countries, and/or still work in favor of the prolongation of the capitalist dominant classes over the laborers. So i.d.k.

It’s out of topic, but i’ve also learned an hour ago that Ethiopia owes a lot of its debt to China, even if they were always “rebel”/unique that’s a “good” way to ensure fidelity, that’s what we(sterners) are/were doing, but this whole world sucks on many levels(, and could get worse), technology has progressed enough to solve every problem we had in the past, we can now do the work of hundreds/thousands with our machines and yet we still haven’t achieved a paradise on Earth. Worse, in the west we don’t even talk about the future that we want to build, we don’t have public plans to achieve an imaginary capitalist utopia(, we’re even saying that things will be worse, wtf), realism stinks, i want us to envision the paradise on Earth and to take steps in order to achieve it, not… simply living and electing the least bad representative who’ll govern without our understanding, i.d.k., it sucks but shouldn’t, i don’t get it, it sometimes seems to take more time/money/efforts to move away from this paradise than to naturally allow it to happen, sry for the rant.
