You have a deep knowledge of history and I respect that. To be honest I donot carry grudge towards the new generation of British people but their ancestors did lot of damage to my nation as well and We will never forget that. Be it ruling India for 200 years and the deadly partition of India and Pakistan in 1947.
Many humans are totally responsible for the broken chain of historic knowledge as you correctly said.
My heart goes for the bushfire incident and many such natural calamities that took p-lace in recent years.
But now we need to unite and change our perception for goodness of mother Earth and absolutely learn from the advanced ancient technologies.

Thank you for your good thoughts and I wish you great day ahead.
