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.

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.

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.

We, the Social Democrats, are convinced that capitalism needs to be tamed a second time. The first time we achieved that in Germany for many decades with the social market economy. That is no longer enough. Now we need to do it in Europe and even globally.

I'm hearing different things, but there is concern that stable Germany is no longer quite so stable.

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.

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.
