> ... that sounds more like a military alliance between independent city-states in ancient Greece than your average human friendship. It doesn't sound like your average friendship in modern atomized societies. But it seems that it was the bedrock for many societies throughout history, including close knit societies today. I've heard it argued fairly persuasively that this is why military insurgencies tend to be stronger in societies where kinship groups are fairly strong (and there's a strong possibility atomized societies wouldn't be able to follow suite).
