Don't underestimate India , it can make everything but only under the right and knowledgeable leadership. However, it will be timely issue. This is the Only issue, we are procuring technology from foreign countries.
No nation in the world is fully self-sufficient. Yes, even the might USA....MIND IT, 95% OF RAW MINERALS COMES FROM CHINA, USED IN EVERY SINGLE ELECTRONIC.
If india want to be self sufficient (more than 80-85%), by itself, it can take more than 4-5 dacades. Creating Infrastructure alone will take a lot of time, educating and then the tuffest part is R&D. Is it possible, he'll yeah.
India will be producing, finest of the finest minds in the world, but it will take time. This govt understands it very well. Not to mention, there is a huge hole in our military gap, hence procurement is utter nessesity.
As far as ur comments about, if India made any thing by them selves..........................This shows u know nothing g about India. I will be creating a new thread, either today or tomorrow. Im sure, it will be entertaining.
