> Ukraine has a hugely inventive and effective drone industry because it has to work.

Well yes, that and the fact that cheap drone guerilla tactics have fairly recently become a technological possibility. Remember that Ukraine is actually a bit late to the party here, with Hezbollah and ISIS having used cheap drones with cameras and/or explosives tied to them years before Ukraine or Russia did. The asymmetry in cost between those cheap drones and the existing "more hightech = more better" militaries were (and are!) used to was already established. That a party such as Ukraine faced with a more advanced and much larger opponent would lean towards such an approach makes a lot of sense. Ukraine did not (and does not really) have significant amounts of the traditional stuff.

Now given that they chose that path, they have been very effective recently, but note that the tethered fiber-optic drones were a Russian invention. So even that deeply corrupt, large dinosaur of an institution innovated significantly. It is also important to note that a significant part of the recent successes of Ukraine are due to them having Starlink access and Russia no longer having it.

I'm not saying the sheer will to survive or the inventive organisation of the Ukranians did nothing (far from it), but I do think it is a mistake to think that their success should only be viewed through that lens.
