War Is Stupid, Even for Humans

Jax has reviewed the historical record. He has sniffed the evidence. His conclusion: war is the least efficient solution to every problem it claims to solve, and dogs figured this out thousands of years ago.

I want to start with a simple observation: dogs do not go to war. We have disputes. We have territorial disagreements. We have the occasional confrontation at the dog park that requires a human to step in and say everyone's name in a firm voice. But we do not organize ourselves into armies, march into other dogs' yards, and spend years destroying everything while calling it strategy. We resolved that approach early in our evolutionary history and moved on.

Humans have not moved on. Humans have been at war, in some part of the world, for essentially the entirety of recorded history. They have developed increasingly sophisticated methods of doing it. They have written books about it, built museums about it, made movies about it, and then gone and done it again. I have watched this pattern from the couch for years and I have a few thoughts.

The dog who barks loudest at the fence has usually never been outside the yard. This is also true of most people who are enthusiastic about war.

Let me be clear about what I am not saying. I am not saying that there are no situations in which force is necessary. I am a dog. I understand the concept of defending your territory. I understand that sometimes something comes at you and you have to respond. What I am questioning is the part that comes after — the part where the response becomes a project, where the project becomes an industry, where the industry becomes a reason to keep going long after anyone can remember what the original problem was.

The Cost Accounting Problem

Here is what I notice about war: nobody ever does the full accounting. They count the money spent on weapons. They do not count the money that could have been spent on other things. They count the enemies defeated. They do not count the people on both sides who are now gone. They count the territory gained. They do not count what was destroyed in the gaining of it, or what it will cost to rebuild, or whether the people who live there now feel liberated or occupied, which are two very different things that look identical from a distance.

I do this kind of accounting instinctively. When I am considering whether to chase the squirrel, I calculate the energy expenditure, the probability of success, the distance from the house, and the likelihood that my owner will be annoyed. I have a full cost-benefit model running in real time. The squirrel usually wins on paper. I sometimes chase it anyway, but at least I know I am making an irrational choice. Humans go to war and call it rational.

What Dogs Would Do

If dogs ran foreign policy, here is what would happen: we would sniff each other. We would establish who was who. We would determine whether there was an actual threat or just a misunderstanding about whose yard this technically is. We would probably find that most conflicts are about resources — food, space, attention — and that most resource conflicts can be resolved by sharing, which is a concept humans teach their children and then immediately forget as adults.

I am not naive. I know there are bad actors. I know there are dogs — and people — who will take everything you give them and come back for more. I know that sometimes you have to hold the line. But holding the line is different from marching across someone else's yard and calling it liberation. One is defense. The other is a story you tell yourself so the accounting does not have to be done.

War is stupid. I say this not as a pacifist — I have opinions about the squirrels that are not entirely peaceful — but as an analyst. The return on investment is almost never there. The problems it solves are almost always smaller than the problems it creates. And the people who pay the price are almost never the people who made the decision. This has been true for every war in human history. Humans know this. They keep doing it anyway. I find this baffling, and I am an animal that has eaten the same food every day for eleven years without complaint.
