If go by race and ethnicity. India would be divided into many states because of differences in the states. But as India was formed by the British Raj, I can see the reason why it want to restore itself to the glories of the British Raj. However, do not expect India's neighbors to just lay down and roll over as India pursues 2nd hand imperialistic policy.
and also when u rn't even aware of how india was ruled and what governed it why throw statements.... Delhi was always considerded to be capital of India no matter what and who ever ruled Delhi was called or presumed to be the head of state.. and there were some dynasties which ruled a major part of India at different times of history... THats the reason why I say, Boundaries change and nothing is concrete as u people try to justify...
