It takes a lot of work for society to advance - not just technologically but in customs, mores, tolerance and freedoms. It's sad to see progress become negative . While war isn't the only way this happens, it has the additional sadness associated with loss of life. I'm not sure I'll ever quite understand how two (theoretically) closely related groups can escalate their differences to the point that's occurred in the middle east - I guess the real question is how do you help both sides realize what they're losing?
