Or they can just look on Google Maps? That will contain most features like foot bridges etc. I think the US would probably be the hardest country in the world to invade due to the amount of arms people have, even if you got past the army somehow you’re still in trouble. Has any thought been given to arming civilians in Taiwan as a further tactic to prevent invasion?
