The quota idea is a good one, but there are two problems with it. The first is clear: A quota system would also require all European countries to be prepared to take refugees. And secondly: What happens when the quota has been filled? Would we then simply tell those who are threatened, sorry but we have to send you back?

I know people's problems: the problems of those who work hard, who must slave away. The couples who have two incomes but who can nevertheless barely cover their rent. The people who get stuck in traffic on their way to work. The people who have to wait in vain for a train to come just as they are supposed to be picking up their children from daycare. I can say with a clear conscience to those people: I understand your problems. And I will do all I can to decrease them.

Complementing the nation-state as it reaches its limits amid globalization: That is what Europe must offer.

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.

CDU head Angela Merkel has tried for years to serve two sides: the conservative side by holding up her CDU party membership. But then at the same time she acts as though she were also a Social Democrat. I don't have this hydra-headed nature. In the end, people will vote for the Social Democratic original.

The Social Democrats have to listen to people who are attracted to the AfD party. That isn't a mistake at all. You can also win them back. Of course, there are a lot of angry voters who are ideologically charged. But there are also a lot of quieter voters who plan on voting AfD to send a message. We can never give up on them.

Donald Trump is not just a problem for the EU, but for the whole world.
