We are hardwired for protection and expansion of resources. Pre-Industrial societies were tribal based and so the group was the most important asset where everyone’s roles were interchangeable.

Durkheim called this mechanical solidarity. The Modern period brought the opportunity for individualist expression which gave rise to specialists in the Industrial Revolution. Durkheim would call this organic solidarity and so a greater affinity for disparate groups became evident placing a greater emphasis on nationhood rather than tribalism

Nationalism is tribal in its essence and demands a unity of purpose from its members. However with the rise of populism in recent years, the political environment is forming, as we can see globally, around individuals rather than party politics. Left and Right are less important as we move toward neo-tribalism with specific interests and agendas.

Factionist warfare could be a future as factions rather than nations engage for dominance: The Wars Of The Roses but with more lethal weapons and the equivalent Battle of Bosworth Field taking place in cyberspace rather than the countryside of Leicestershire.

I saw a YouTube video of a group of male chimpanzees staging a raid on a neighboring clan. Chimpanzees are our closest animal cousins, so yes, I’d say that war is in our blood. Young male humans in cities are forever forming up into gangs and waging war—further evidence.

Just because some behavior pattern is in our genetics doesn’t mean that we are slaves to that behavior. Maybe conscious awareness will step in at times and direct us into more fruitful ventures. Libertarians generally oppose war. Vote Libertarian.
