Last time used faced a conventional military that could actually challenge it was in Korea.
It won’t have complete areal superiority or entire division surrendering after running into contact with US forces like they in Iraq. “Shock and awe” of course can be very effective just probably not against China. Even now US is running out of materiel against Iran and can’t really sustain a prolonged intense conflict while being able to protect its gulf allies from ballistic missiles and drones.
Iran is not a war funded by congress, so it's really no wonder the US appears inneffective. Trump didn't get the support he thought he would from congress and now he's flailing around trying to save face.
Change the leadership (which will happen soon) and when there is actual support from congress to fund and intervene in a conflict in Taiwan, then you will see a vastly different US military response.
