In an interesting video, TIK talks about Germany’s access to oil and oil supplies and why these dictated its actions during World War II, and why they made its downfall all but certain:
It is said that when it comes to war, amateurs think in terms of tactics and professionals in terms of logistics. This is related to the saying that an army fights on its belly, that is, if it’s not fed, it doesn’t fight.
Feeding and watering an army—both men and horses—has been the concern of generals for thousands of years. (Horses were often relatively self-sustaining, since they eat grass, but they do better on grain if you want them to be constantly working.) Thus tactics like burning crop fields during retreat, so as to starve an invading army.
World War II was in many ways the first truly mechanized war, and thus the problem of logistics expanded into the economic sphere. Machines are produced only by a thriving economy, and machines run only on oil. In order to fight an effective mechanized war, one must have a strong economy and lots of fuel.
This, by the way, has strong social implications outside of war. In order to remain in peace, one must have the strength to defeat attackers. In order to do this in the modern context of mechanized warfare, one must have a high-production modern economy. One doesn’t need to be able to produce the weapons of war oneself, but one must be able to buy them. That requires a modern economy, which requires at least much of modern social organization.
Those who want to bring back the good parts of traditional social organization need to understand this well. Whatever form modern society takes, it must be one that powers a modern economy which can power a modern army. If it’s not, it will be short-lived.
