I hate to say it, but as long as there's testosterone, there will be war. It's stupid, useless, tragic, horrendous, and the worst criminal act humanity has ever committed.
But there will be war.
It's said that the more one studies war, the more one hates war. I think that's true, for I've studied war since my youth, and I *hate* war. But too many men love it. Be prepared for war, or be prepared to lose when someone declares war on you.
