Sir, Indian armed forces are known to procure a mix of foreign proven platform and indigenous developed systems, thanks to their lack of full confidence in home grown weapons which I believe is understandable.
Being developed, will provide, will be as good as XYZ are the phrases which compel them to go for some well proven ones as well. War becomes imminent when enemy find you weak and can get through with his objectives with minimal loses. The idea of raising another corp doesn't comes from nowhere but when it becomes imminent.
More than the war, a strong hold assures a better negotiation capability and we can not let border issues go forever.
However I do agree with your need of indigenisation to lower the cost and induct self dependency but not on the cost of operational capabilities. I guess the latest trial of dhanush must have pour in some confidence in armed forces who in turn might have told finance ministry about it.
Anyways whatever I have written is not unknown to you.
