Once they start killing I think they’ll work out any kinks pretty fast.
I expect that if we start fighting and survive long enough, it will be us (and other Western powers to a degree) that will work out the kinks and get back on track, probably after much loss of life.
The big question is time, of course.
However, tyrannical governments such as the Chinese Communist Party do not have a track record of making this happen. The Soviet Union and the Germans do not count, as that was less working out the kinks than it was bringing massive amounts of manpower to bear with the weather as your ally.
And Communist China does have an industrial base (largely taken from the West in what can be characterized as a zero-sum transaction) that is going to be a problem for us, and the question is how to survive long enough to reconstitute what is needed. It may not be possible in a wartime environment.
Additionally, the maxim that “Quantity has a quality of its own” also comes into play.
And all of this assumes that the Left has not managed to destroy the advantages we might have in independent thinking and action by then, and denuding the military of the values it needs to be able to “work out the kinks”.
Point is, I don’t think that assumption you made is a done deal. As a society, we have a better chance of “working out the kinks”, IMO. That is, if we don’t
This is not underestimating an enemy, which is a dangerous thing. This is a realistic estimation.
