The economics of this kind of warfare make no sense to me. The Harkonens must have been incredibly wealthy by running the spice trade, but even after years of saving and plotting said that the transit fees to move the armies by the Guild were ruinous.

How could anyone wage war like this? The defenders will always outnumber the attackers.

Lays out an interesting take on this: that armies are quite small, even on developed worlds, because the cost of equipping them is enormous — and the technological advantage is absurd enough that you don’t need a large army. When 300 men can hold a planet, why would you need 1000?

So less guys with knives and more WH40k Space Marines. Impossibly expensive elites who cannot be equaled by a mortal.

Still leaves me questioning how anyone could wage war. If the Harkonens could barely afford it, nobody can.

Also wondering if the Guild charges different rates for goods vs military. What is worth the brutal intergalactic shipping prices that you would not develop local industry to create it? Surely nobody is moving grain or ore, yet the Guild ships are portrayed as comically massive.

But they accepted the transit fees, which means they endorsed the action.

The guild would not allow any action to jeopardize the flow of spice. Thus any attack on Dune is implicitly sanctioned, notwithstanding their spice trade with the Fremen.

This is why I love Hacker News. Come for the AI system outage root cause, get a treatise on the power of the spacing guild in Dune.

Even today (and back when Dune was written), modern military tech is invincible to an enemy below a level of sophistication. The US used to hammer insurgents with Predator drones who had no ability to retaliate.

This playbook has only flipped due to a lot of cheap tech (and the machinery to make them) coming in uncotrollably to these countries has put them on a much more equal playing field.

Since the Guild controls what comes in, they can avoid this scenario from happening. They can control who can have what, and who can make what. Which I think is one of the true, deep explanations of why military tech in Dune is so weird and inefficient - essentially the efficiency and power of a weapon is dictated by how much the Guild charges for shipping them if they allow you to, at all. Which is how you end up with dudes with swords. It gives an idea of the level of technology in the universe that you can equip said dude with a nigh-impenetrable shield that fits in a belt buckle. I guess that's the result of optimizing for Guild transit fees, not real-world power.

Really it's not exactly a novel idea, but as I think more about it, it's uncanny how Dune (at least initially) is basically the fantasy Suez crisis and what followed. It explores the power dynamics very well, how factions can hold humanity hostage without firing a single shot, and how what they don't bother controlling comes to bite them in the ass.

Which is exactly what ends up happening, but it does take a bunch of extraordinary events.

Both today and when Dune was written the superpowers were being bogged down in unwinnable conflicts due to the effectiveness of asymmetric warfare.
