because going to war is easy. deciding to go to war is hard. weigh the benefits against the deficits. weight the heart against the material. then realise, that it was always war anyway. then finally realise that others realise that too. the only logical conclusion is to war. however, what is the point if you'll just get old and tire anyway? the answer? eternal life. first you achieve that technology, then war to your hearts content! hahahaha!
