Ms. Merkel's attempt to present herself as a Social Democrat was a clever move. But it's not working anymore. The divisions between the CDU and CSU have simply become too great for that.

The dream of Europe is a region of freedom and peace, of security, law, democracy, tolerance and mutual respect. If you look into the faces of the refugees you will see this dream. These are people who are fleeing from war, hate, violence and unjust systems.

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.

France is ready for a European revolution and it is Germany that is pulling the brakes. For a long time, it was the other way around. You don't have to agree with the details of every single one of Emmanuel Macron's suggestions, but he's right about the idea of a new foundation of Europe. Europe's Social Democrats have long demanded this. If we really want to, we can create a different, better Europe in the coming years.

I find it surprising, however, that many German politicians generally oppose referendums, but then when it's an EU matter, they immediately scream for a plebiscite.

A joint European army is a very far-reaching proposal and it would be difficult to implement. Such initiatives are nevertheless needed.

Turkey has in interest in finding agreement on more permissive visa requirements, it wants to be recognized as a safe country of origin and it wants to finally return to constructive EU accession negotiations. We Europeans decide all of those things together.
