After Lisbon treaty EU became some kind of mixture of the union of independent countries and a single organism. "The force" that is supposed to bind all countries into a single organism are EU council, EU commission and EU parliament. The real power is in the hands of the first two institutions - that's the EU bureaucracy which became a modern days "monarchy" - people does not have any power to decide who is nominated to those bodies and those bodies can do whatever they want. EU parliament is pretending to be some kind of "democratic" control, but, at the end of the day, everyone votes "properly", if not, voting is repeated again and again, MPs are disciplined, some words are replaced with their smoother version and we get what we were supposed to get.
