Refugee & Schengen crisis

The EU is experiencing the world's worst refugee crisis since World War II. The terrorist threat is also very serious, particularly when it comes to radicalised EU citizens traveling to, or from, conflict zones. In response, member-states are re-instating national borders, and the EU is reconsidering the Schengen agreement. If left unsolved, both the refugee and the terrorist crisis could eventually become a Schengen crisis, which, in turn, will be a blow to the European project itself.
