What could war possibly teach you? Sometimes I feel when observing Americans online that you people are forever teenagers. It's like you don't grow up. Did you see some book online or a movie or something that teaches men discipline and how to be a man and be strong and wise or whatnot. Did you hear about the art of war book. Is that what prompted you to ask this question. War doesn't teach you anything boy. If you can only learn by killing eachother than the society we live in is pretty primitive and boring. I consider us evolved enough to learn not by trial and error but by simulation and reason. Learning by war it's like learning by religion. A myth and smoke mirror.
