A war would not achieve any worthwhile aim. (Starting a war to teach its adversary a lesson is what the CPC does, not India). A war would be inconclusive and end with a 'LIVE' LAC. https://twitter.com/vskochar/status/1286507671491756032

The better option for India is to make the LAC 'LIVE' without loosing manpower & eroding its war fighting ability. A live LAC implies troops holding tactical positions based on terrain & supply lines not based on a hypothetical line on the map.

A live LAC would allow India to leverage its better trained, equipped, informed (through surveillance & intelligence data from its allies) and motivated troops and air warriors. A live LAC would include cross LAC forays by Special Operations Forces (SOF)

Occupied Tibet's terrain & people would make cross border ops easier for India than similar operations by the PLA. India could also close Chinese SLOC through IOR. A festering conflict, Indian geopolitical belligerence with help from numerous powerful allies will wear China out

Tibet will once again become disputed territory. Western intelligence agency would seize the opportunity to exploit existing race and religion based fissures in China aggravated by the dictatorial CPC. China will quickly loose all the gains it has made through coercion in SCS.

India's aim would be to seek a border settlement that is acceptable to the Indian people. A live LAC and Indian belligerence with near world wide support will achieve that aim at a lower economic and human lives cost. A war will achieve nothing but only make the LAC live!
