Yes, 50 years later, we are the 2nd largest economy in the world.
Back in 1962, China and India had similar sized economies. Today, China's economy is FOUR times bigger than India's, with commensurate military spending.
We have the largest bilateral economic relationship in the world with the USA, and we co-founded the SCO with Russia.
Back in 1962, we were enemies of both the USA and the USSR. Yet despite India's pleading, neither of them came to help. So if they didn't help back then, when we were their enemies, how does it make sense that they will help you now, given the above?
