Are you sure it’s a legitimate news story? Could also be a “nothing to worry about with China - please focus your attention on Russian interference” piece of agitprop on behalf of CNN’s Chinese masters.
No, I think you are not right on this one. Amphibious invasions are very difficult with today’s modern missile technology and that is highlighted a lot here. It would be a nightmare to try to land enough invading forces for this. And you can assume most Taiwanese at this point are prepared for defnding the island since they’ve been preparing forever for this. Kind of like Nazi Germany leaving Switzerland alone. Every Swiss, by law, owes firearms/weapons and are trained and the geography makes guerilla warfare a constant. Similar situation here.
