Nothing to defend lol the invasion, when it happens wouldnt last half a day before these weaklings ship even sets sail.
They r in direct range of artillery stationed on the mainland, its like shooting across the street
China launches a missile, western weaklings detects it, calls their commander in chief, yada yada, he calls an immediate emergency meeting, generals rushed to the command center, yada yada.
Should taiwan province declares seccession, they would immediately becomes traitor to the country which obviously punishable, which makes it very, VERY easy for the Chinese to deal with. Right now they r Chinese citizens so theres not much they would waste effort on, once they become traitors, the mandate and law will be extremely clear. Apart from usual minimising civilian deaths, they can level the island rebuild it.
