Why are you talking about apologies if there is no guilt involved?
I don't understand this concern with apologizing. if I realize I've wronged someone, I feel guilty until I admit my wrongdoing and apologize. The apology is part of amending the relationship. I don't know how one could fix a serious screw up without an apology, actually.
I don't feel personally responsible for what happened to the FN people before my time. Nonetheless, I want my country - through its leadership - to make amends to them. It's just the right thing to do, imo.
As individuals, I guess we each have to decide how much amending we'll do on our own.
