Germany is to be contained from outside and heterogenized from the inside by influx, 'diluted' so to speak.

We had to move forward after the war and see the realities.

With the arrival of the refugees in 2015, it became impossible to ignore that the period of uninterrupted sunshine that Germany had enjoyed had come to an end. The vast problems of the 21st century are knocking on our door. That is also true of the dramatic changes that we can see globally, for example with Brexit and the election of Donald Trump. You can't win people over by saying nothing and biding your time, as Angela Merkel has tried to do. People want leadership - in the best sense of the term.

There are a lot of active AfD members in Germany and people in party leadership positions who speak like Nazis and think like Nazis.

I had hoped and thought that our society had advanced beyond that. But we have to realize: They're back.

I never use the concept, multipolar. I use multilateral. Because we have only one global power: whether you like it or not, this is the United States.
