If we could only get the Chinese to spend all their R&D money and science/engineering talent on increasingly complex and expensive weapons systems we could bring down their whole system.
Congratulations; you've successfully described the Strategy of Technology. which used to be a military textbook.
"A gigantic technological race is in progress between interception and penetration and each time capacity for interception makes progress it is answered by a new advance in capacity for penetration. Thus a new form of strategy is developing in peacetime, a strategy of which the phrase ‘arms race’ used prior to the old great conflicts is hardly more than a faint reflection.
There are no battles in this strategy; each side is merely trying to outdo in performance the equipment of the other. It has been termed ‘logistic strategy’. Its tactics are industrial, technical, and financial. It is a form of indirect attrition; instead of destroying enemy resources, its object is to make them obsolete, thereby forcing on him an enormous expenditure….
A silent and apparently peaceful war is therefore in progress, but it could well be a war which of itself could be decisive."
--General d’Armee Andre Beaufre
And anybody denying that technological war works needs to take a good hard look at Ukraine. The Russians dropped out, and ended up so far behind that their equipment wasn't capable of competing with western weapon systems. (Which to be fair, they didn't expect to encounter)
As a result of which, light anti tank weapons were able to blow up soviet battletanks.
Shoulder launched SAM's cleared the sky of aircraft and helicopters.
Cheapish anti RADAR missiles destroyed Russian Surface to Air Missile batteries, allowing their army to be bombed from the air with impunity.
Russian Infantry found that their rifle bullets didn't reliably penetrate the modern body armour that the Ukrainians were gifted.
China might well be interested in competing, but they can't do so against the combined Military R&D of every other country in the world, and I suspect that they know it. North Korea and Iran have seen what happens when massed collections of outdated equipment clash with a small subset of modern military technology countries were willing to share with Ukraine, and will realise that they haven't even been given a lot of our heavy equipment because we don't want to show what it can actually do. I think they'll have lost any appetite for foreign adventures that they might have had.
And so after Russia finally accepts that they have lost in Ukraine and gets out, we can say welcome to the Pax Technologia.
