Let me just say something very simple, and you can think about it when you have time
China vs America war is only the war btw these two, USA cannot count on S.Korea or Japn at all. S.Korea will not let USA use ANY of her bases to attack China, if they do, China will conqure S.Korea. Japan will not let USA use her bases either, if they do, they can count on Chinese missile strikes (high explosive pre-nuke ones).
If USA don't have bases to take off the airplanes, then only from Carriers.
Now we are going back to our old Topic about "How to attack Carriers"
Don't forget this: MAD is applied to both China and America, EVEN IF China runs into trouble handling US jets, China can do some mini-nukes into Carriers groups, or just explode 2 H-bombs 500 KM afront of the Carrier Groups, then USA is pissed off, there is no hope more for America, game over
