Irish, Catalan, Basque, Galician
A few factual points :
There are plenty of Albanian speakers in Greece (although most consider themselves Greek), as well as in Italy.
The case for making Russian a working language of the EU would be based on the large Russian minorities living AT PRESENT within the EU, mostly in Latvia and Estonia. There are also quite a few Ukrainian and Byelorussian speakers in Poland and Lithuania. If Romania is allowed in to the club, as will apparently be the case, that country too has numbers of Ukrainians. I don't think the EU would make the language of a neighbouring country a working language, but if there are several million speakers of a language within the EU's borders it would seem to be fair.
I wonder how many speakers of Mandarin, Cantonese, Arabic, Urdu, Hindi etc. live within the EU ? Hmmm.
When all else fails in the world of politics, a people - any given people -will revert to a distinct national language to foster a cause of patriotism or nationalism. In fact this is one reason why the English are so bad at nationalism; their language, English, has in fact become virtual international property, and therefore no longer "theirs". Practically all nationalisms attempting to influence the course of politics will resort to the promotion/protection of the national tongue/dialect as a rallying point for independence movements. Allowing minority languages to survive in the EUby giving them special status, will simply ensure the survival of tribalism within the Union, and therefore ultimately, it will bring it down (the Soviet Union and Yugosalvia are but obvious cases in point). in my perhaps minority opinion, the EU an only survive if one tribal language becomes the norm (Latin in the Roman Empire). English is widely spoken both 1st/2nd language, but I suspect that opposition to English from anti-anglo forces within the EU (French, perhaps German, as well as minority tongues - Irish, Welsh for historical reasons) will scupper that idea. It is for this reason that ironically, I believe that England specifically will leave the EU, whether as a member of Britain or as an independent state. This will leave French/German as the dominant languages. We will then see a idealogical battle between the Germanic and Latin speaking world, which could in itself, crack open the fragile EU.
In some ways having your native language...in my case English, which we are discussing anyay, as a world lingua franca is a curse. It instils a reluctance to undertake the bother of learning any foreign language when practically the whole world and his wife understands yours which, sadly, is quite widespread in Britain. Maybe in other English speaking countries as well, notably the USA I guess.
It's true that the English don't make good nationalists. In the main it's almost a crime in England to be outwardly patriotic except in a sporting context, and they do not celebrate Englishness in anything like the same was as people proudly proclaim Scottishness and Welshness and Irishness. In some parts of metropolitan England with large immigrant populations local authorities ban (or at least frown upon) the display of the St George of England flag in case it "upsets ethnic groups". If that isn't bizarre then nothing is......actually waving the flag of England in England and being censured for it. If people from elsewhere choose to live in England then they should accept the status quo in England even if it means St George flags from every lamp post when it has nothing to do with football or Rugby or cricket or any other national sport.
It's just the English St George flag that seems to act as a red flag to a bull in this context. We can wave the Saltire till the cows come home and nobody complains, whatever their ethnicity.
**I believe that England specifically will leave the EU**
In spite of the rise in the anti-EU UK Independence Party vote in the UK May elections, and the constant rantings and ravings against Europe here in the UK, I reckon it'll be mega unlikely that "England" will opt out of the EU...even more unlikely would be for England to act unilaterally in this respect, again whatever anti-English rantings and ravings constantly go in in Scotland and Wales.
However strong the anti EU feelings are in the UK....among a portion of the electorate anyway....by no means is this attitude universal.... many people with an ounce of functional grey matter would know that it would be economically very harmful to us in the long run if we were to secede from Europe as much of our trading activities are within the EU.
I think it's a safe bet to say, though, that the Euro will not replace the pound Sterling...not in the forseeable future anyway. That IS something the electorate here would vote against in any referendum, whatever Phoney Tony would hope for.....but he's on his last legs as PM anyway. :-)
