I think you have a seriously outdated view of Chinese military capabilities. All your analyses consists of what the US can do to China, while ignoring any consideration of Chinese countermeasures.
You're essentially playing chess against yourself.
But that is basically the crux of the discussion here (playing chess against yourself).
It’s not really the capability that’s the issue. It’s really whether the scenario presented is truly reflecting reality. This is what people are having the most trouble with.
One of the assumptions is that US will just reroute global forces after pacific forces are annihilated. Meanwhile China would not have global reserves to draw from. At the same time, the diminished PLA capability will open them to direct attacks on the mainland.
If we assume that today’s US Global forces are more capable than today’s PLA (not the PLA in 5 or 10 years), then from a military perspective this is all true.
We know this isn’t realistic for a number of reasons, chiefly amongst them would be economics. If a war broke out Tesla and Apple would basically become worthless overnight which would destroy the stock market, take down a lot of pension funds, then subsequently drive down real estate prices in all major cities.
Taiwan would literally not be worth it. Part of America’s global power is wealth, so shotgunning yourself in the face in a way that would put Kurt Cobain to shame would be stupid to put it simply.
Second, such a wasteful sacrifice of American military assets would basically leave its ability as world police in tatters and who knows what that means for places like the Middle East.
Also we have history to draw from as Thatcher did hilariously tried to assert British sovereignty over HK like Falklands, but we know that ended with her literally falling flat on her face.
However, this is the chess game that has been set up in this part of the thread, so it’s what we are playing
