The EU is bound to fail sooner or later because it lacks the unifying culture that is necessary. And that involves one language. Even at its very beginning it would never have got beyond the original six countries if all their leading politicians didn’t have English as a secondary language so they could it around one table and conveniently talk together..
For all the quasi-democratic words that are batted about in second-hand English by politicians of the 28 countries and which are supposed to bind them together, they all have different cultural meanings. But outside the conference rooms or the corridors of the Brussels’s civil servants the French remain strongly French, the German German, the Greek Greek and so on. A European cultural tradition can never emerge and that is the death knell of the EU.
