Let us get back to the topic. I think we are beating Nukavarapu-garu's thoughts too much.
Why/How/When/If PRC attacks India is one question.
What/How/Where India draw its battle lines is another question. Here I am assuming that India is not initiating the war with China
{Is there any scenario where India would initiate a war with PRC?}
I would like to bring the focus on to India's defense preparedness.
What would India need to defend against PRC+TSP joint action:
