Political leaders need to formulate long-term EU goals that show: Yes, we want to stay together.

In the days before the vote, I bet that the British would stay in the EU.

I believe that the majority of people in Europe want to demonstrate solidarity with the refugees.

In all of my encounters with voters, I have repeatedly been confronted with two points of critique. First: You politicians are all the same! Second: You politicians may be speaking German, but we still don't understand you!

Complementing the nation-state as it reaches its limits amid globalization: That is what Europe must offer.

If cooperation among governments were the superior concept for progress in Europe, I'd be onboard immediately. But the problem is that cooperation isn't working.

I have no illusions. Of course, Russia is massively upgrading its military. We know that Russia is pursuing a policy of expansion. This is of course a cause for concern among Eastern European countries.
