Metternich once said Italy is a geographic expression.
And he was right. Tirol has as much in common with Sicily as Quebec has in common with the Yucatan.
The question is, who will take up the Iron Crown of the Lombards?
Most countries are geographic expressions as borders tend to be natural and defensible, i.e. a river, a coastline or geographic barrier such as a mountain range. Or boundaries are defined by anti-bellum treaty. In any case ethnic consideration as a self evident claim for national boundaries are a modern phenom from the 19th century- see the Messestrict treaty which redraw Euro political boundaries. Nazi Germany used this argument to claim the Sudetanland, Austria and the coal regions of France.
