The dangerous glorification of the nation state, and the baiting of minorities that goes along with it, releases an anti-democratic energy.

I would never attack somebody only because they belong to a different party.

It was clear to me that the White House's solemn atmosphere would not civilize Trump. But the merciless nepotism with which he conducts politics, in which he places himself and his family above the law, I wouldn't have considered that possible. And on top of that there is this reduction of complex political decisions to 140 characters. When it comes to a U.S. president, I consider the reduction of politics to a tweet to be truly dangerous. Trump is a risk to his country and the entire world.

Imagine a German as president of the European Commission. If he or she goes to some particular country and says do this or that, it won't be very well received. The president quickly ends up being the evil German. But if the president is elected by and controlled by 700 representatives from all EU countries, that legitimizes him or her in a very different way.

Trump believes politics is a staged fight. But it is not. Still, clear words are sometimes needed in politics. In that sense, I believe I am better than Mrs. Merkel.

We're at a historical juncture: A growing number of people are declaring what has been achieved over the past decades in Europe to be wrong. They want to return to the nation-state. Sometimes there is even a blood and soil rhetoric that for me is starkly reminiscent of the interwar years of the past century, whose demons we are still all too familiar with.

I cannot guarantee people absolute fairness. I can only promise that I will do everything in my power to secure fairness or create a greater degree of fairness.
