True but i think Bharat Verma forgot to mention the amount of technical knowhow that DRDO has achieved over the years. Getting things from outside without knowledge, of how to piece them together is equally dangerous. Why should we be at the mercy of outsiders, when we have the talent within. Having said this i think what DRDO has achieved is remarkable.
Yes i think the scientists have to put in more effort now, to get us the best level possible in the closest possible time.
