I think about this all the time, and I just thought I'd see what other people think.
I don't think we can solve our issues through politics or wars, we just can't. We have been killing each other since the dawn of man and what have we gained from it? A redistribution of power? Finding new creative ways to kill each other? It just dumbfounds me how we have learned nothing from our history. Most wars have been over religion, and that's a serious issue but I don't want to get into that. The only real way in my eyes towards unification is leaving Earth. I don't think it would eliminate our problems immediately, but it's a step, and it would take time. Discuss!
