The greatest threat from China against Taiwan is the vast buildup of missiles facing it, not any Chinese carrier. A carrier does allow China to fly more sorties, or faster sorties at least, against Taiwanese targets. However, China can already fly sorties from the mainland. It doesn't need a carrier to do that. An anti-carrier boat is nice, but not essential to Taiwan's defense. Taking down those missiles (or some good portion)? Much more essential.
So, because I refuse to believe that groups like this never do anything for blatantly illogical purposes, what's the point? What's going on? Is it just balancing against a new threat (while ignoring the bigger, present one), or is there a hidden strategy at work?
