I have seen enough of it from the USA to Europe, North Africa, Japan, Korea, Central and South American from 1945 to 1968. Yep I was Military, E8 when I retired. Right now I think love and understanding each other, accepting individuals for what they are and not what color, race, religion or nationality they might happen to be. Enjoy life while you can. It can never and will never be.
War is natural.
Conflict is natural. Survival of the fittest. We need war, just as we need hate. Without hate, love is nothing. Just as without war, you cannot appreciate peace.
