I have to aggree that you are right, but as time goes by we learn by experience and perhaps in another 300 years or so we will either not be here or more importantly we will have learned to communicate with each-other properly and settle our differences through negotiation and dialogue. There is always hope. With every passing day the world is becoming much more interconnected, and as a result of this we are becoming more and more dependent on each-other for our survival. For an example - all of the nations on the world are threatened by the onset of climate change and the natural disasters which will inevitably occur if we do not tackle this issue as a whole, if the planet goes - we all go with it. There is no choice, either we all work together and get on-board with the solution or we all perish together.
