There were talks about escorting Pelosi's plane into Taiwan airspace with fighters, shooting down Pelosi's airplane even, yet China was cautious, smart, and proportionately to their salami slicing with its own salami slicing (routine air exercises). What I am saying is the war hyperventilation leading up to Pelosi visit was hysterical level and predictably ended without a bang.
Taiwan may be untenable as of now, which really started with the Pelosi visit.
A total blockade of the major Taiwan ports is completely doable, if or when it is required.
These air patrols sure looks like complete air dominance. Have to be expected, as Taiwan is outgunned, by numbers and by better fighters in the air.
Establish a corridor of full control of the sea lanes, and that is done by air, then the PLA can land anywhere they chose. Wipe out all defenses, then land.
If the PLA establishes a corridor that they control from the mainland side to the Taiwan side of the strait, then it is very difficult for the Americans to dislodge that. They can try, but over time, they all will get killed, and China will do the 3rd, 4th, 5th wave of that.
All from the Pelosi visit.
