I am critical of the fact that Hungarian Prime Minister Viktor Orbán is pulling out of everything - the joint approach to the refugee issue, for example. He cannot disparage his colleagues in the EU either - that's not how we treat each other. We require solidarity: in refugee policies, just as in the financial architecture of the structural funds from which countries like Hungary have strongly profited from for years.

Turkey is doing an enormous amount in the refugee question, but it can't continue to pay for everything by itself. That is why we have to talk to Turkey about money.

The racist rhetoric that extends all the way to the top of the AfD shows that one must assume that an attitude is prevalent - not just in the grassroots, but also among party leadership - that is not consistent with the basic values reflected in our constitution.

I believe the people should have the opportunity to have a greater influence on politics with their ideas. We need a new impulse for renewal.

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.

But if you constantly insist only on your own interpretation, it isn't long before it seems patronizing.

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.
