It would be a waste of energy to review why the Indian military would get crushed. The point I want to make is understanding the Indian mind. Indians are very prone to making grand self-assessments. They genuinely believe India will become a superpower in 20 years. So, if India and China are equal great powers, border each other, and have a dispute then confrontation is inevitable. India sees itself as preparing for the future of dual superpower confrontation by since 2009 massively upgrading its force levels and infrastructure along the boundary leading to the current Ladakh confrontation.Not that this idiocy should be entertained, but China has 200+ fifth generation fighters. India has how many?
There is one strategy insight that can be gathered from my observation about Indian grand self assessments. The pathway to peace with India is to persuade them their future is bleak. Remind them they are still growing only modestly fast and are 50 years behind China. It will take them until the 2070s to get to the GDP per capita of China in 2021 (inflation adjusted).
