A high-risk plan to deny the Taiwan Strait

How could a coalition control the Taiwan Strait and prevent an invasion?

Use carriers east of Taiwan, submarines and Marines around the strait, and mines at invasion ports, but expect major civilian-risk and propaganda problems.

The military outline places carriers east of Taiwan, submarines in the strait, and Marines ashore while mining the harbors from which an invasion force would depart. That layered scheme attacks air cover, undersea movement, local access, and embarkation points rather than relying on one barrier. The proposal immediately raises the danger to civilian shipping in crowded waters. Empty civilian ferries could be sent into the minefield or represented as occupied afterward, creating an information-war incident even without the claimed deaths.
