What makes you think there will ever be a SUCCESSFUL global community that will be lasting when its human nature in countries to want to dominate other countries. It there isn't peace within families you can bet there never will be between countries.

At the same time it's nothing to worry or get hysterical about either. Just live life responsibly as it comes. Besides, I believe God is in charge of the big picture though we are responsible for caring for the environment we live in
