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.

There's no point whining about missed opportunities.

We must now, in the 21st century, protect democracy, one which rests on fundamental rights for all, regardless of skin color, gender, race or religion. Nothing less than that is at stake.

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

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

Referendums are a democratic instrument, but so are decisions reached in a parliamentary democracy. I advise extreme caution when it comes to referendums. In Germany too.

Donald Trump is betraying everything that made America great: tolerance, democratic institutions and respect for the individual. In that sense, Trump is the most un-American U.S. president that the country has had in a long time.
