> It probably wouldn't have been at peace since 1815 if it had not had enough defences to put off other countries from invading in WW1 and 2.

This is a oft repeated myth. Switzerland would have been conquered within a day by any major power in ww1 or ww2. The reason why switzerland isn't conquered is because they serve as a money laundering/transfer center for every power. Swizterland's "defenses" are for show. Swizterland's shield is it's dependable position as banker for nations and the elites.
