Trump has a clear goal: the division of Europe and the destruction of the European domestic market. The fact that Brexit propagandist Nigel Farage was the first European he received in his tower speaks volumes. That is why we must strengthen the European domestic market and work even more closely together in Europe. That is absolutely compulsory for Germany.

I'm fully aware that my vision of a European bicameral parliament can't be implemented tomorrow. I'm also not an integration fanatic.

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.

At the end of the day, men like Donald Trump need to be given that which they themselves dispense: clear messages. I would confront him as clearly and explicitly as possible. It is not only the right, but also the duty, of the leader of a German government to do that.

Gerhard Schröder offered a clear German NEIN to an American president's war of aggression that was in violation of international law. That took courage. Ms. Merkel did not join him at the time. If Trump now begins to take the wrecking ball to our set of values, we must say clearly: That is not our approach.

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.

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.
