I would love to see a truly People's Republic in India as well. But let us be real. The Soviet Union happened in the aftermath of the first world world war. The PRC happened in the aftermath of the hundred years of humiliation and the second world war. Whereas the material conditions of present day India show no way forward to such a communist takeover of India. So China has got to deal with this problematic neighbour no matter what. And there the pragmatism of the CPC is clearly on display.
Replacing a shitty enemy with a competent socialist one is a bad idea. India is hostile across all political spectrum. Much like a communist Vietnam did not solve the hostility. It merely swapped from US aligned enemy to Soviet aligned enemy to independent enemy. Partly it is a geographical reality.
If they have any aspiration of dominance, China is an unreachable barrier. Can there be a compromise with China? May be give up the continent, and try dominate over sea? Lets be real that is not happening either, still goes against Chinese interest.
So long live the Indian Hindu Empire. May it long live a thousand years so they never pose a threat. A socialist revolution in India is an existential threat. Current India is a nuisance. 1.4 billion people with competent government and nuclear arsenal along with imperialistic tendency must never exist. Socialism will not stop imperialism, we had Soviet Union already.
I don't know what it takes for India to drop hostility. Perhaps it is destiny for a local great power to fight local superpower, if the said great power has any aspiration for greatness. I can hardly blame them. Or perhaps it is a cultural issue. How do you fix culture and power imbalance peacefully? You cannot. So if the hostility is caused by a long term physical reality, then no compromise can be made.
Better to dismantle Indian Empire so it has no aspiration to compete, than to please them on short term. Better to do it in a time when China is at peak than letting India ambush during a revolution, like Japan. Hell they already pulled one off during covid, imagine what depravity they commit had China had civil war?
