Certainly. And I've pointed that out many times in discussions regarding India.Sure. Buying foreign weapons is a double-edged sword. It has good and bad sides.
May be true. But the biggest problem with people who are too smart is that they can't see the hole right under their feet. India is not so smart, it is to their advantage, they need to solve the immediate problems, while continuing with their long-term plans.
China bought Su-27, Kilo class, S-300... China was not rich at that time. But it was the right decision. China can save a lot of money to invest in the economy and society, if he decides to wait 10 or 20 years. But China choose to buy. The same is true for India.
Sadly, it's not good news for China or Pakistan. India faces many difficulties, but that does not mean they will give up. India is like a bicycle, the speed may be slow, but it keeps going. China needs to be careful and not look down on them.
But ultimately, it is an odd and worthwhile thing to ponder about. Almost every developing country is this metaphorical bicycle. I can say that Pakistan will eventually "reach", or Indonesia will or Vietnam will.
The idea is to catch up fast enough. There is no fixed goal. Development never stops. It's a moving target. If you have a Volkswagen, you'd want a Mercedes. If you have a Merc, you'd want a Bentley. But by then, they'd have moved to luxury yatchs and Business jets.
