The concept of the is poster is a visual play on the European Union flag. Instead of the stars in a circle, the stars are part of a barb wire fence, a natural barrier to keep things coming in or out. In this case, to keep migrants from Africa and the Middle East out of Europe. However, the fence is also to keep those who live in fear of migrants in. Recent waves of terrorism in and calls for isolation has fueled campaigns to leave the EU, like the UK referendum. Being isolated is a dangerous in itself, which can fuel nationalism and extremism.
