The major challenges facing the Europeans – such as terrorism, the migratory crisis, and differently "Brexit" as well as the rise of anti-European populism – call for the redesign and revival of the integration of a united Europe. These various challenges should not be treated separately, in a fragmented manner but rather put in perspective and addressed in a structured way. They all bring into play the Europeans' ability to rise together to overcome the series of crises they are facing. However unity cannot be taken for granted. Indeed extremely strong political tension is threatening the cohesion and stability of the European Union.
