The European community of values is unique: It combines democracy with the market economy, individual freedoms with social justice. How can we expect the U.S. or China to defend these values, this one-of-a-kind European balancing act that has developed over the course of decades?

I am very interested in writers from the Francophone world. I like Kamel Daoud a lot, for example. In "The Meursault Investigation" and "Zabor," he shows a passion for the French language, a very special way of writing that belongs to those who live on the other side of the Mediterranean Sea. It is language that connects us. It allows people there to cling to our history, our culture and sometimes also our values.

Donald Trump is the head of a global power.

Many European parties, including the conventional parties in France, no longer have the ability to keep people together. And in terms of the coalition government, I am convinced that Angela Merkel has the necessary will and ambition. I want to be very cautious with my statements about her coalition negotiations, but support for Europe is part of the DNA of both the Greens and the Free Democratic Party. I was very pleased that the heads of both parties spoke out positively about the European project.

I often speak with Turkish President Recep Tayyip Erdogan. When I speak with the Turkish president, I defend European positions. That is how we European partners must do things.

Post-modernism was the worst thing that could have happened to our democracy. The idea that you have to deconstruct and destroy all grand narratives is not a good one.

Look at me, the Front National got many more votes than the Alternative for Germany. Marine Le Pen ended up with 34 percent of the vote, 34 percent! I defended Europe, an open society and all my values. The Front National has been significantly weakened. In the debates, you don't hear anything from them anymore - because we engaged them in battle. Now is the time to be bold! The only answer to the Alternative for Germany is courage and ambition.
