Finding the right form of debate regarding Israeli policies will remain a challenge in Germany. Even with every conceivable and warranted criticism, the danger always arises that it will be exploited by those who consciously or unconsciously present anti-Semitism in a new guise.

Less and less is the question being asked as to whether developments are taking place in a democratic and free way. Europe is in a phase in which this output is no longer sufficiently visible or tangible. Youth unemployment is still far too high, we still haven't solved our currency problem and living conditions in Europe are drifting apart. That is one reason why critics say that our Europe is based on yesteryear's model.

It is clear that there are reasons for discontent in Iran - economic and political reasons. We have told the Iranian leadership repeatedly that the country's economic recovery can ultimately only succeed through greater international economic cooperation. And the precondition for that is not only that Iran refrain from developing nuclear weapons, but also that Iran's role in the region become far more peaceful. We have offered to finally hold true negotiations and talks on that issue.

However, I have a low opinion of people with narrow political horizons. Someone who talks about the environment and knows nothing about economics can make as many mistakes as someone who does the opposite.

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.

Turkey is currently seeking to make itself more independent from Europe and is turning to the east. Is that in our interest? Does it help us bolster Western values in Turkey, or at least here at home? Or are we making ourselves weaker overall? At the same time, Turkey is violating our European moral concepts. It's a difficult conflict to endure, and it leads to necessary disputes and debates.

But, as environment minister, I am very interested in a thriving German automobile industry, because I can only pay for the rising costs of environmental protection at home and abroad if there are people in Germany with jobs and who pay taxes.
