Vorarlberg joins Switzerland in 1919

[True Federalist (진정한 연방 주의자)]

In the real world, Vorarlberg, the westernmost Land of Austria, held a referendum in 1919 on whether to join Switzerland in which the vote was 80-20 in favor. However, Austria didn't want to let them go and Switzerland didn't want to take them.  Suppose the Swiss are willing to take them and the Allies force Austria to let it go.  What effects would such a change have?

Liechtenstein becomes an enclave in Switzerland, I think that is the only significant change. Vorarlberg is a small state.

Vorarlberg avoids the worst ravishes of WWII and the Anchluss as part of Switzerland (Hitler wouldn't bother, anyway I doubt he ever wanted to  attack Switzerland); apart from that, nothing really of note.

[Undisguised Sockpuppet]

Nothing.

No one going to postulate an irredentist Austria that attacks Switzerland in the 1930's?

[Tetro Kornbluth]

No, because no-one really ever wanted a war with Switzerland over a rather unproductive piece of terriority. Hitler had bigger fish to fry or if you're talking about earlier, Dolfuss would want to risk a major European war by attacking Switzerland. (which would no doubt make him the ire of many major bankers and the "upper class".)

That wasn't the point at all. Tirol and Salzburg both held referenda at the same time saying they preferred to join Germany than be parts of a truncated German-Austria. (With 90-10 type results... actually, in Tirol an independence option was included and got some support as well.) The Vorarlberg referendum can be understood only in that context.
German annexation of Tirol and Salzburg was vetoed by the Entente powers. Vorarlberg joining Switzerland would only have happened had the Entente not done that.
However, in that case it's doubtful whether that's where it would have stopped. More likely, all of Austria would have become part of Germany in 1919. In which case it would probably still be.
One might wonder if the Weimar Republic would have worked better if Prussia hadn't still been such a large chunk of the country... if WWII could have been miraculously avoided this way... but I very much doubt it.

Not much of a difference. They even speak like Swiss. I wouldn´t miss them

But they bring in revenues! Lots of German tourists.
