As a Brit I'm happy to admit we did some shitty things in India, as well as elsewhere, during the colonial era. However at this point we're both happy members of the commonwealth with a decent relationship and a decent amount of cultural osmosis from each other. I mean our current prime minister is of Indian descent.
There's a different between India and some other ex-colonial nations in that they aren't still moaning about it and saying they need reperations, etc 70 odd years after the end of the empire. India got on with it as an independent nation and become one of the world's fastest growing economies.
