When the name has been widely known for 100 years, how to change it?

Now like popcorn, it has a process

1. Change on visual which is covered by International Media. and hence the name on the Plane is BHARAT

2. Put BHARAT name in front when the World joins you at a party and Media covers it. G20 from PM to President to all displays visible to Media was BHARAT

3. Display the centuries-old deep-rooted culture to the world and the very foundation of your country. G20 had Sanatan all over, no Mughals were in center stage as they were invaders

4. In The United Nations where you have the entire world, the greeting is "NAMASTE FROM BHARAT"

5. Let people within the nation and all over the World adopt the name and let it sink in thoughts in a natural way

It will take 5 to 10 years but surely, one day it will be BHARAT, not INDIA
