Donald Trump has made the principle of purposely breaking a taboo into a means of achieving his political objectives, which is something that he has in common with Turkish President Recep Tayyip Erdogan and Hungarian Prime Minister Viktor Orbán. Trump systematically violates international rules. But we cannot allow ourselves to forget that Trump is not the U.S.

The vast majority of people support the idea of an enlightened, modern union of countries demonstrating solidarity. Film director Wim Wenders recently summed up the problem to me very well. He said the idea of Europe has become an administration, and now people think that the administration is the idea. But that doesn't mean we should give up on the idea - it means we should change the administration.

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.

I am grateful to the Germans in general, particularly those who displayed unending dedication to the refugees and who continue to do so.

Donald Trump must be taken seriously. He is fulfilling his dangerous campaign promises.

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.
