If Indian wants attack Beijing or Shanghai, Indian has to use inter-continental missile, which has to fly over the Tibet plateau or south east China to reach the target. Considering the stage of Indian's inter-continental missile, this is quite easy to detect and knock it down.
In your dream, you can have everything. Face the reality, Indian. The reality is that Chinese can deploy their army as well as equipment three hundred kilometers away from the Indian Capital city and put the Indian's most essential area - Ganges area under their conventional weapon attack range.
Except Russia, no other main players in India ocean want India to do capacity building on navy. These countries expect India to put its main resources on ground army.
USA of course, wish India can contribute to the counterbalance to China, but definitely doesn't want India become a dominant...
At least it can calm down the tension a bit now. I think Chinese feel necessary not to escalate the situation before the completion of Sichuan-Tibet railway. I might be wrong.
There is severe limitation on physical work on the plateau due to the lower concentration of oxygen. Construction work heavily depends on machinery operation over there. I think probably few of captured Indian soldiers know how to run the construction machinery, which made Chinese to release them.
First of all, Chinese probably thought there is no necessity to keep them. Secondly, that is an apparent signal releasing to the world, which side dominated that hand-to-hand battle.
I don't think it is Chinese induced the outbreak of COVID in India. It's India elites who live in EU flew back to India after the pandemic out-broke in EU.
If that news can make you Indians feel happy, please enjoy it. As a Chinese media pointed out , Chinese government doesn't want to release the details of casualty to put fuel to the fire of Indian society. RIP
The 12-dash line is the consequence of post-WW2 order and was drawn under permission of US at 1947. If you think the current international order is unfair, then lets fight and establish another one
