Why China did not invade India after Indo China war in 1962?:

Such a large scale war is simply not possible, simply due to the fact that the Himalayas act as a huge natural border, and despite the huge buildup of infrastructure from both sides, it is very very difficult to get more than an expeditionary force across the border, especially considering the fact that the mountain passes will close during the winter, leaving troops essentially abandoned.

For this reason, India has little to lose in a major confrontation with China in terms of its territorial sovereignty, but still India needs to stay wary of the fact that any war that would happen would be for the control of Arunachal Pradesh, and China has the logistical power to send more than enough troops to hold that state, although not enough to descend into the valleys of Assam, where Indians have a huge advantage and China needs to outnumber at least 3:1 to win convincingly.

However, we need to remember that although many nations are disgruntled with China as local industries are being killed by cheap Made in China products, this is not enough of a reason for intervention in a war.

Russia will not side with any side, as China is a major trade partner for them, and both sides buy a lot of weapons from Russia, and hence they will probably just sell weapons to both and try to get a ceasefire ASAP, perhaps even stepping in with negotiations as a mediator.

USA will show support for India at the moment, although it is unlikely that they will actually go to war with China over us, maybe if we started to lose too badly, and same as Russia, they will try for a ceasefire, but will with support to India until and after this is achieved.

Now come our real allies, Israel, who has stuck with us throughout Kargil and our other Pakistan conflicts, they help us with weapons and will be happy to help us in our fight, although they will not commit boots on the ground, so their support will be limited to moral and material.

France and UK, with whom we have close military and trade ties, will probably end up doing the same as Israel, because some of their MP’s in parliament are pro-India, and they will be influenced by the stance of the US, alongside Germany.

China’s main support will come from Pakistan, and this will put real pressure on India, that if we are not careful this could spiral into a two-fronted war. It seems unlikely that the advent of a two-fronted war would change much in terms of support, because of how unlikely such a conflict is, and also because of the fact that such a military stance would lead to aid from other anti-China parties, such as Phillippines, Japan.
