Look at the words you chose:
Disaster
Permanently
Soon
Biggest
Then potential and eventually.
That's really how YOU think.
Yes to mirror that sort of moronic logic, India then has also committed an even greater strategic disaster. It has permanently made itself an enemy of a nation which could have potentially partnered with it in developing its own industries as it inevitably spends and invests its growing middle class expendable income much like the west had in the 60s to now. The western outflows and investments have declined and while they still have an appetite for inexpensive consumerables, India is nowhere near the point of delivering all of those. Not barely even able to deliver on some of those yet.
Once Chinese investments are banned and pulled out, India is free to dwell in the same slum and slump its proven to be in for the last 80 years. What a strategic blunder of epic proportion. It's also totally lost 5% of its annual income and THE world's current biggest market and the one that actually has the funds and capital to buy things. India's got headcount but the rest of its metrics are in the sewers... wait sorry, I mean on the street level. Sewers haven't reached many parts of India yet.
Shit I think my satirical rebuttal makes far more sense and is actually grounded in facts and reality. In other Indian news, 500 pieces of Brahmos missiles have defeated China, a nation with tens of thousands of offensive missiles.
