Would unloading supplies on Taiwan's east coast and moving them through the mountains make resupply impractical?
Short answerThose are constraints, but ships with their own cranes and existing transport links prevent assuming that all eastern resupply is impractical.
NotesAn assumption of makeshift ports overlooks the difference between ships with their own unloading cranes and ships dependent on shore facilities. Existing ports, coastal routes, and roads through the mountains complicate a blanket claim that eastern supplies cannot be distributed. Attacks on cargo movement also depend on locating it in time. Transport vulnerability alone therefore does not demonstrate successful interdiction. Destructive capacity and the ability to achieve a durable outcome remain different questions.
