People have not, and will never change. I don't believe humanity has gained any mental or physical superiority with time, in fact, I believe that with today's comfort we have simply become senseless of our true abilities.
The government would never want to make 'atomic warfare in Ancient India' common knowledge as it would then belittle what knowledge and technologies they have 'accomplished' today. Therefore we will not be learning about it in schools or seeing it on the television.
We must learn to never let nuclear weapons become humanity's ultimate self-destruction in the future.
