Yeah it's pretty insane that Americans would go to length describe all the things they need to win against China: massive industrial base, a huge logistic support fleet, bases with close geographical proximity, and then only go so far as saying US don't have those yet / need to build those.
If they go a single step further in this train of thought, they'd arrive at China infact do have everything in that list, and might even figure out the entire island chain concept doesn't actually work in combat, and they're infact China's defensive advantage, that's its China who has the geographical, logistic and industrial advantage needed to occupy and take advantage of those islands.
Case in point, Americans spend so much time wargaming trying to prevent a PLA landing operation onTaiwan from their base in Okinawa, they never stopped to think what to do if China's landing operation is on Okinawa.
Infact if you keep going with this train of thought, you'll actually arrive at the final conclusion which is the geographical distance between CONUS and Hawaii, and the total lack of islands between them is a huge vunerability to the US, because by the time China pushes to Hawaii, US forces will both be degraded and be at a massive logistictial disadvatage trying to defend anything west of California.
