Is invading Taiwan comparable to Germany trying to invade Britain in 1940?
Short answerChina is much better equipped for the task than Germany was for Sea Lion, but Taiwan remains a very difficult and unattractive invasion target.
NotesA Taiwan invasion is a poor direct match for Germany's 1940 plans for Britain. The People's Republic of China has real amphibious shipping and trained formations, so the operation is feasible in a way Sea Lion was not. The comparison still shows that crossing defended water into difficult terrain remains an exceptionally risky choice.
