In a full scale conflict, carrier group would be sunk by subs in the first 15 minutes. Those carrier groups are a relic of the past that only works against unsophisticated adversaries who do not have the largest submarine fleet in the world [1] or nukes. US military planners know this so any such things will be withdrawn shortly before shit is about to go down, or (more likely) never brought in in the first place. And it doubly does not work against adversaries without whom we can't even build anything because we outsourced all of our production there. In 2 years we couldn't even scale the production of N95 face masks on US soil, let alone anything more complicated. The colossus has legs of clay and US government (and its owner - the US business establishment) is to blame.
Prediction: Taiwan will be retaken by China by 2030 and the US will do bupkis about it other than saber rattling. It can't even do sanctions, since that'd be sort of like US imposing sanctions on its own manufacturing base. Xi knows this. He will use our weakness to his advantage. It would seem that business establishments are already acknowledging this, hence this massive investment in the US. On the other hand, this is also forcing China's hand - they can't afford to wait until it becomes feasible for the US to impose effective sanctions. Their colossus too has legs of clay. Except the legs are not as weak.
