The new social question is: democracy or the rule of the financial markets. We are currently witnessing the end of an era. The neoliberal ideology has failed worldwide. The U.S. movement Occupy Wall Street is a good example of this.

Those who reject integration programs in the long term have as little right to stay in Germany as a hate preacher paid from abroad in a mosque.

What we have at present is a system of loss socialism. Whatever goes wrong is shouldered by the general public and anything that works is privatised. Worshippers of market freedom have suspended the most important economic principle: Risk and liability go hand in hand.

Economically and politically, Germany is extremely stable. There are countries with functioning governments whose institutions don't work. My only concern is about Europe. There's a risk we will run out of time. We have been blessed with a pro-European French president, but we are also approaching the next elections for the European Parliament in 2019, and it will be important for pro-European parties present a credible answer to the anti-Europeans on the left and the right.

My office has a view of low-cost housing, old East German prefabricated apartment buildings. It isn't an attractive view, but it's very helpful, because it reminds me to ask myself, whenever there is a decision to be made, whether the people who live there can afford our decisions.

Iran is the only country in the world that's threatening to erase another country from the map as part of a collective genocide.

It is clear that Germany needs a foreign policy in which we jointly define European interests. Thus far, we have often defined European values, but we have been much too weak in defining mutual interests. To preempt any possible misunderstandings: We cannot give short shrift to our values of freedom, democracy and human rights.
