Again, you don't understand my argument at all.
Of course the goal of the war is to make others to submit by force and pain. That's obvious
But you missing my point.
If in the near future multilateral system, governed by AI, drones and robotics. A war is nothing more than a war of attrition between economies, then in a global interconnected economy with scarce energy, it will become an absurd proposition because one nation can't cause significant bleed in other without bleeding itself.
Without human involvement and other players forces energy leakage in the global economy, it's not hard to see how. In fact we are seeing right now. It's why Trump is pulling back.
