> Back in reality, it's true [China] could ... sink 15 aircraft carriers [in an hour].
That is unlikely. The Chinese military relies on a combination of overwhelming manpower and tactical positioning, not aircraft superiority and tactical missile deployment (although they are equipping with more and more ballistic missiles). This puts the US at a distinct advantage in almost every conflict with the Chinese military. This includes the South Seas.
The presence of the 5 US carriers* off Singapore has deterred the staged Chinese invasion force for the last few months

2 More were sent by Trump in September (https://www.youtube.com/watch?v=mvgKgLVPckA). .

That same adversary wouldn't sink a second [15 carriers in the next hour . . . 'cos they'll all be sunk]
