Interesting proposition. It has often occurred to me that we are one of natures experiments in extremes that has gone too far. Saber toothed tigers developed teeth too big to be practical. We may have developed brains too big for our own good. Our reach exceeds our grasp, or at least the grasp of the least of us, and they are legion.
I think part of our brains may be overdeveloped and part underdeveloped.
We are more interested in "things" than each other
More interested in "winning" and being right that peaceful assembly
If we are meant to be "warriors" by nature, the only true winners will be shown by brute strength, because, opinions vary and even views of reality vary.
It's because we're programmed for survival, not for morality.
Unfortunately.
There were certainly no winners in WW2, everyone seemed to suffer involved.
Furthermore, and untold number of geniuses were probably killed in WW2.
Another Einstein, or Edison may have been killed, and this might have regressed Humanity's production / intellect.
Yes, WW2 bought about tolerance of biblical proportions, one which will lead to the most productive race, (Whites) to eventually be replaced.
