and nothing of note has happened in any of them since World War II.
the timeframe does not appear to be pinned to the Renaissance period. Further, the quote I replied to was from The Third Man a movie made and released in 1949 that was set in post world war II Vienna.Further again, that quote appears to address present era Switzerland 500 years after the infamous time of the House of Borgia.
2/ The OP is about San Marino; the quoted excerpt is referencing the European city states of San Marino, Liechtenstein, Monaco, and Andorra; hence the flow of comments you point at is not concerned with Switzerland per se.
3/ The referenced quote is nevertheless false, because cuckoo clocks were invented in the Dresden in early 1600s; only popular culture associate them to Switzerland.

Things would be very different in Switzerland if it bordered the Eastern Bloc or the Mediterranean Sea.
