Well, I couldn’t include the entire history of India in a HN comment. I didn’t include Bangladesh as the initial question was related to regional tensions and Indian-Bangladeshi relations are pretty good, as compared to Indian-Pakistani ones.

I also said mostly which most commenters seem to be missing. In any case, I only made the comment to point out Aurangzeb, not engage in a debate on British India.
