>Denmark
Different language compared to the rest, closer to other scandis. There was one meme proposal in the 1800s but that didn't go anywhere
>Dutch
Fought an 80 year independence war against the habsburgs who wanted to genocide them for being Protestants. Those Habsburgs were also the holy Roman emperors/kings of Germany, so to revoke any claims the Habsburgs could have used for reconquest, they distanced themselves from other Germans
>Switzerland
Wanted to be mountain hermits left alone to do their jewery and banking more than they wanted to be German (though apparently there was some contention about this in the 1800s I think? Idk)
>Austria
Britain and France, helped by America, kept them separate by force to weaken Germany in any future conflicts. Then, after WW2, to get out of paying reparations and being occupied they "switched sides" and claimed to be a victim of the nazis, and psyopped themselves into thinking they're unique, different, and special
>Luxemburg
Under Personal union with the netherlands at the time unification went down, so would have caused complications and maybe another war to annex them, ala Holstein with Denmark. They would have been integrated had we won either world war
>Liechtenstein
They were physically separated, from the "mainland" by Austria and Switzerland, that's it mostly. It's so small everyone just forgets about it
