I am a Brit, but not really bothered if someone calls me British.
Swede/Swedish, Scot/Scottish etc etc
Maybe not the same thing, I dunno

If I were a Croat (or a Croatian for that matter) I'd be more concerned that my nations debt had risen by 13% last year (to 26 billion Euros)
Croatia is ranked as one of the World's most highly indebted countries by the World Bank. If they don't do something about that, Croatia could become categorized as a "high-risk" state.
This would cause available credit lines to decrease, interest rates to rise and just generally a bit of a bad-ass financial crisis.
