When is the last time Switzerland has been invaded? Or at war?

And I am sure that Swiss men don't feel like peace is any threat to their manliness either.

Helps when you're willing to bank Nazis gold while the rest of the continent was being conquered or trying to resist. Also helps to have US led NATO provide cover against the Soviets.

They also banked plenty of English gold too :-) That's what "neutrality" means; you are not neutral if you refuse to do business with one of the warring parties.
