In the language of the prince of darkness, IAF current operational doctrines is nonsense and need to be torn up and thrown in the dustbin.
Foreign buy should be the last resort of IAF. It should happen when there are no other alternatives available. That is how most 'professional' Air Force behave. Pampered air forces on the other hand has a different take on things.

In India the human life is less valuable that the value of life outside India (especially compared to richer nations). Not just civilian life, but non civilian life too. (No that there should be any need to be say that explicitly). Indian Army, Air force, navy need to suck it up and live the Indian reality rather than hang on to the reality of British India and their army traditions.
There is no moral ground here .... just cold reality.
Pouring 2 billion $ into the LCA 10 years back would have resolved most of its problems by now. I happen to be in the aerospace industry.
