Well - it does not make any sence for the Swiss to produce their own norms, since they are simply too small that it would pay out. I.e. think about a own Swiss (or Irish - hihi) plug connector. Your Irish man with his Irish plug connector would look like the late Karl Marx in no time if you would leave the green island with him because his electric razor simply needs electricity to work. That is the way things go since physics are everywhere the same.
Positive nationalism is okay, I like people who love their country, but ignoring the the rest of the word is complete cretinism. The Swiss know that. Therefore they found their way to arrange themselves with the EU without being a member. This means that they have to live in a bigger frame like all of us.
We could simply dismantle the EU - it serves no purpose to the benefit of Mankind whatsoever.
