Yes the war showed some new aspects, but relentless low capability drone attacks is not the same as flying an F-35 into enemy air space and bombing their critical resources with high accuracy thanks to sensors.
Mass manaufacture and drones and such need to be take into account in the future, but when it comes to what is easer to counter, mass drone attacks or F-35, ill be money on the mass drones being countered first.
There are already many system that can deal with drones quite well. Old school FLAC with improved sensors, fast shooting system, even cheaper drones as counters and of course lasers and so on in the future.
Yes S-300 doesn't deal with drones either, but its pretty clear what to develop to counter-them, how to counter F-35s is not nearly as easy.
> The enemy can launch barrages of drones from hundreds of kilometers away, outside the F-35's effective range.
If they are doing that these drones are no longer as cheap and if you fly against modern anti drone weapon that have costs of a few $ per shot down drone, the economics is no longer in your favor.
