Thanks Todd I appreciate your feedback and your experienced insights. Tribalism and nationalism are based on a village mentality, as opposed to seeing all people as members of one global village. Human nature does seem a bit immature still ,like a child. You would think we had better realization by now. We have come some way though, for example when we see the EU - nations have united much more than in previous centuries where they fought wars more regularly. Now we just need the continents to unite, although even with the UN we have not succeeded yet. Collaborations in science, as you say, like the International Space Station, set a good example of team work beyond borders, while ironically on the ground the same nations may be at loggerheads with each other, like America and Russia. It does seem odd. Let's hope wars will keep decreasing, until it becomes clear to all civilization that they are outdated.
