I think it's because of language. If there was one official European language, as primary, it would be easier to unite the people. Language is the greatest divider. Just look at Belgium, or Spain/Catalonia, France/Corsica, it is still dividing people. I don't even think Google Translate would help, because it could well be mainly the result of different languages causing different systems of thought.
