In the aftermath of the Arab Spring and the Syrian conflict, Europe has faced a wave of migration from the Middle East. One of the great achievements of the European Union has been the Schengen agreement, which creates open borders within the EU itself. As a tide of refugees has entered Europe, however, there has been a backlash, and many EU members are implementing what they call temporary border controls. For Greece, which is the typical entry point for migrants, many of whom come from Turkey, this represents a serious problem. If migrants or refugees are unable to follow the Balkan route to major Western states or Scandinavia, then they will remain in Greece, which lacks the resources to support them. The EU’s internal divisions on how to address this issue are creating serious internal tensions, at the same time that Britain is debating whether to exit the EU. To better understand the threat to the Schengen area, look at this map and blog post at Political Geography Now, which concisely describes the key issues involved.
