The Japanese committed unspeakable cruelties against the Chinese but today the Chinese fans mob the Japanese skating and pop superstars. Somehow Russia, China, Japan, and the USA are able to be friendly trading partners despite historical animosities.
Or should the long historical and continuing warfares with mutual vilifications going on in some parts of the world be the model for the state of Homo Sapiens? Should holding on to decades old hurt and misplaced vengeful sensitivities be more respected than establishing relationships among equal human beings of today's generation? Should oppressed people be shunned when it's been shown over and over that reaching out and connecting, opening their eyes and minds, and letting them know of support and caring from more fortunate fellow human beings lead them towards their liberation more than military actions, sanctions, and condemnation of their nation and people?
