Eh if you assume it's only one or a few. This war has been a bad wake up call for china, in theory them plus russia balanced nato and taiwan. Now with russia incompetent(see avdiivka videos) China would have a US, japanese, phillipenes, australian and south korea response to anything they do in the south china sea. And with taiwan and south korea not fully assured the US would support them why wouldn't they try to develop nuclear weapons.
