If we don't answer it in the affirmative we haven't learned anything from the Holocaust or World War 2, meaning that at some point in the future humanity is doomed to World War 3.
Since the League of Nations established after the first World War wasn't sufficiently advanced enough to prevent the second World War from happening, and the United Nations established after the second World War seems insufficient to stop an ongoing genocide and probable World War 3, then perhaps the organization that grows out of the third global conflict will find whatever is left of humanity if anything to finally have reached mature wisdom or national/global adulthood by then?
Of course to anyone who has played the game (s) "Fallout" this seems like a dim potential reality as well.
"War never changes" aka for all it's immense power the human species is too fearful, greedy and stupid to grow up.
We don't seem to give teaching, or learning about the humanities its due in our education system. They don't readily match up as well with our monetary based value system.
Compared to us, the Dinosaurs were extremely successful primarily because we as a species don't seem to have the emotional courage or intelligence to match our technological power.
