I don't know what the path forward is but imo it doesn't change that the wrongs of the past should be acknowledged.
John Howard not only publicly acknowledged the wrongs of the past, he also expressed deep regret that they occurred.
However, he quite rightly believed that the present generation of white Australians are not responsible for those wrongs, and therefore should not say sorry for something in which they played no part.
Sounds pretty reasonable to me.
