Lets see:
A gator fleet, some upgraded destroyers, and 13 new submarines added to their collection of old Soviet era Kilo's and less than a half dozen homebuilt nukes.
Compared to the US Seventh fleet, this is one days work, even with the Chinese work in missile and anti-ship technology.
And if the 7th fleet isnt enough, there is always boomer floating around to make the scorecard even.
That's if we ever decide to use the 7th Fleet to defend Taiwan. China's economic prowess, her ever increasing hold of vital oil resources, her control over the Panama canal, her road mobile ICBMs, etc., give China a larger and larger stick/carrot to "convince" Washington that maybe standing in the ChiComs way isn't quite worth the pain that such a move would bring.
That are many ways to defeat and adversary, on the battle field is just one of them.
