> we'll need the people to actually fight the war itself.
Will we? It appears to me that modern war works substantially like modern factories - you don't actually want a large mass of semiskilled workers to pull the levers, each of which can substitute for a different one on about five minutes' notice. You want relatively few, highly-trained specialists to instruct the ~~robots~~ drones. It is perhaps less true in war than in manufacturing, quantity still has that quality all its own, but it seems very unclear that just raw numbers of soldiers will be an important bottleneck as between Great Powers.
I'm pretty sure most of the robots and drones are manufacturered in China though. Even if they weren't, a lot of critical components for building things come from there now.
