It isn't myopia at all to think that near term conventional large-scale nation-state warfare is unlikely. I'm well aware that industrial giants of the last half century aren't as dynamic as they once were, but it hardly matters. We have tons of talent and capacity, it isn't unlikely for newer and better companies to be built.
The only important thing where we seem to be at a serious disadvantage is in chip fab, but there are several companies looking to break ground on new facilities in the US in the next few years.
Trying to hand-wring over an unlikely war seems unproductive. There are two major powers today, and we have an extant model in living memory for how to keep tensions below a critical level. The Chinese plan to compete with the West via the Belt and Road initiative seems unlikely to lead to anything other than economic conflict.
Belt & road, ya, that isn't a big threat yet, but the ongoing relentless expansionism is a real threat. They have never stopped, and barely slowed down.
Sure, continued appeasement can 'keep the peace'. But it will be at the cost of sacrificing Taiwan and everythign in the 9-dashed line to the fate of Tibet, Hong Kong, and the Uyghurs. And then whatever else nearby that they will decide to fabricate a claim for. And so forth, and so forth, and so forth.
That is the bargain that authoritarians always strike - constantly cheating around the edges - what's mine is mine and what's yours is up for grabs.
So, people not thinking strongly or long term can argue that "it's unlikely", "it's not worth a conflict", etc. Meanwhile more territory and people fall under authoritarian control.
If it is unlikely, it is because people want to keep their heads in the sand and appease instead of make current conflict. It's a fools game
