Does the EU really need the UK?

The Brexit accident has made the entire world to talk about crisis of Euro perspectives. Well, does the EU really need the UK? Let it go! You don’t accept those want to be with you and cry about those want to leave. Where is the logic here? If you are afraid of disappearance of the UK sponsorship for the EU, yes it is a big problem. But what can you do if Brits wants to leave? The EU must think about the common wealth and new Euro optimistic future members more. Some things should be taken as irreversible. If the UK goes you must wish it luck. The current main goal of the EU isn’t worrying about the UK or any other anti-EU mood but analyzing the problem of poverty in some member countries… The EU must be about the productive collaboration not about the sponsors and sponsored ones.
