There’s a reason why Germany decided not to invade Switzerland during World War 2. The entire country mobilized in three days and they were armed.
According to an old story, a German general told a Swiss general that “Our army is five times as big as yours. What would you do if we invaded?”
The Swiss general said...”All of our soldiers would fire five shots each, then go home.”
Hitler had bigger fish to fry and he needed the railway bridges and tunnels running through Switzerland intact.
