Revisionism won't help, it never does. What happened, happened. The best we can do, as nations, is to work towards good common goals like economic prosperity of our people and contributions to the world at large. I would also like to point out that many good intentioned Indians and Pakistanis turn away a lot of people from the prospect of peace and cooperation between our two nations by the same notion of uniting again. There are examples of nations that have remained independent and have cooperated with one another successfully (the USA and Canada, for example). So let's respect one another but remain one another and not one.
