Sippy chain will be extended? But Chinas air defence is not that easy either. Local Tibetans resisting? There are high amount of hopiums in your post. Just like how Pakis hope - In a war, India will be torn apart from inside.
Local Tibetans and Uighurs rising up is a 100% certainty not just in India-China wars but even China-Taiwan wars. Behind the scenes sabotage is a 200% certainty. Those who have followed wars knows how this works.
I donβt believe in any of the Chinese military technology or prowess. Nothing is proven. All we hear are a lot of shouting and substandard volumes of military equipment being produced. While volume is its own force multiplier, it is not know if these volumes of ships and subs can truly withstand the proven weapons India has. Indi has actually been to war and soundly defeated its enemy several times, some when the country was dirt poor.
China is surrounded by hi-tech powers like Japan, Korea, Taiwan etc. None of them are going to sit quietly during an India-China war as significant investments of theirs are at stake and the world economy will take a beating. India is after all the 5th largest economy in the world with close to $1 trillion trade volume, only increasing from here on. US companies alone have substantial interest in India. And the US protects its corporate interests like anything. Expect total blocking of trade traffic to China in the pacific by the US/Australia etc.
Chinese will starve and run out of fuel before they can inflict any serious damage on India. An India-China war is WW3.
India fought wars when its poverty levels were worse than sub Saharan Africa. It did not get βripped from the insideβ. Have some faith and grow a backbone.
