One last thought about war. Isn't it odd that most people feel vaguely ashamed of sex. Yet what's so shameful? Sex expresses love or desire, or even a bit of aggression, it creates pair bonds that hold families together, it relieves tension and stress, and it creates new life once in a while. Almost everyone needs and wants sex on some sort of regular basis. It feels good and gives mutual pleasure and usually no one gets hurt. Yet it is a source of shame.
While war, which kills and maims and brutalizes, is a source of pride.
Men are expected to be proud of their brave deeds killing other people, and to blush in shame over the fact that they got naked with a person they love.
Something has gone badly amiss.
