Tell me why I should be bothered about ‘x’. This is an agument you often hear when proactive policies are proposed in connection with looming problems. Well a good example comes to mind today.

Of course there are many reasons why we need a Balkans policy in the EU, but if self-interest is what moves you, then here’s an important one.
