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.

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.

The idea that the growing demand for energy worldwide can be met with energy from nuclear power is nonsense.

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.

The production of natural resources in agriculture, forestry and fisheries, stable natural hydrological cycles, fertile soils, a balanced climate and numerous other vital ecosystem services can only be permanently secured through the protection and sustainable use of biological diversity.

A major danger for us Europeans: We must demonstrate that those who have this view of us are mistaken, that we can come to agreement, that we as a community of democratic and free nations are economically successful and are gaining political influence. To do so, we must learn to project our power.

Maybe it is the last chance for Europe to influence standards for world trade. Next it will be between the US and the Asia-Pacific region.
