@Walter Hinteler,
Today, Merkel and Macron are set to sign a treaty in Aachen (Aix-la-Chapelle) that obliges Berlin and Paris to cooperate more closely in what could be viewed as a counter-model to Brexit. That's the right path. The EU needs to show that in a globalised world, it is part of the solution and not part of the problem. This is the most important Brexit promise the EU can make to its citizens.
