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.

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.

In the past, Germany could rely on the French, the British and, especially, the Americans, to assert our interests in the world. We have always criticized the U.S. for being the global police, and it was often appropriate to do so. But we are now seeing what happens when the U.S. pulls back. If the U.S. leaves the room, other powers immediately walk in. In Syria, it's Russia and Iran. In trade policy, it's China. These examples show that, ultimately, we are no longer achieving either - neither the dissemination of our European values nor the advancement of our interests.

In Germany it is good if as many people as possible join initiatives and peaceful demonstrations against the rule of the financial markets. Worshipping the unfettered freedom of global markets has brought the world to the brink of ruin. We now need social and ecological rules for the market economy.

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.

The task for Germany today is - through its own policies and its own structural reforms, its own investments - to support the EU and the Commission... but every nation has to have the courage to broach such structural reforms and speak clearly about them without making people be afraid.
