Why not just accept the situation as part of the ebb and flow of history? They certainly weren’t the first empires in history. I think a lot of the objection is more about nationalistic sentiment than anything else and I don’t feel it needs to be done to reclaim cultural heritage.

Why would you? By calling it the 'ebb and flow of history' you seem to imply that the things we do to each other is beyond the control of humans.
But of course we're fully in control of what we do, so the question is rather: if we have the possibility to do good, and it comes at virtually no cost to us, then why not do good?
