For starters:
A given belief or cultural paradigm could become universally accepted.
The notion of a dominant or supreme group could be universally rejected.
Violent conflict could become universally rejected.
Enough influential people could at least be willing participants to a project for global reconciliation.
Is that a good thing? What does God have to say?
An aside: What is fairness? What is equality? What is peace? How do these aspirations relate to one another? Does a commitment to peace entail relinquishing all defence? What do we want?
Could this become a popular discussion or are our loyalties too strong, our worlds too narrow and isolated, our cultures too shallow?
