Yep - not the whole bleak picture but probably a good guess at what the Battle of Taiwan would require... a shit load of airplanes, missiles, luck and brass balls to fight. Article on what a PRC invasion of Taiwan might look like or their options for a military solution to re-unification: https://www.businessinsider.com/what-a-chinese-invasion-of-taiwan-would-look-like-2014-6 Probably the best Taiwan can do it make the island one giant IED, machine gun and sniper's nest to make any amphibious or airborne invasion enormously costly to the invasion force, a pyrrhic victory at best via a very long bloody campaign. Article at TNR on that subject: https://nationalinterest.org/feature/taiwans-master-plan-defeat-china-war-12510 The best deterrent is the anticipated reaction of the world: Seizure of foreign investments and good luck getting paid on the 2+ trillion the US owes you, no one except the pariah states would recognize their annexation and everyone around you will now arm themselves to the max extent they can afford and probably cozy up with the US and maybe even Japan. Great you got an island with no natural resources, no one recognizes your claim, you fought a very bloody & expensive campaign and the population hates you - big win.
