Yeah, jet names don't fight wars. It doesn't matter if it's caller Viper, Blue Jay, Bunny Rabbit or Cotton Candy.What keeps them at bay is the risk of ignition of a full scale world war with the US.
The way this is framed is to make it seem like a cake walk. Those F16V are vipers in more than just name.
Please, you flatter yourself. A full scale war with the US? China has already announced that it is ready to trade every China city east of Xinjiang in a nuclear war with the US over the ROC. The US has announced... strategic ambiguity... AKA I'm not going to do anything but I can't just say that. If someone asked you what you'd do if a stranger kicked your son at the park, do you have strategic ambiguity or do you tell him you'd go King Kong on the guy in one nanosecond? It's obvious that China is willing to take action and the US, just like in Georgia, Ukraine, SCS, etc... is not, but will complain very loudly.
The only shred of plausibility of foreign power affecting Chinese action is that to take Taiwan by force would cause economic and political tensions with the world, which China would rather not have. But if push comes to shove, it's territory above all.
