Political scientist Herfried Münkler is right: If you only take normative positions, if your focus is solely on values, you won't find success in a world where others are relentlessly pursuing their interests. In a world full of meat-eaters, vegetarians have a tough time.

The G8 nations, together with the five major emerging economies of China, India, South Africa, Brazil, Mexico, use almost three-quarters of the Earth's biocapacity - the capacity of the world's ecosystems to produce natural resources and to reduce harmful substances.

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.

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.

Countries that work with Europe should feel safer than they would if they worked with non-democratic regimes. Why isn't Europe building infrastructure in Africa instead of leaving it to the Chinese? Why haven't we succeeded in promoting the economic development of our neighbors in the Balkans, instead conceding these countries to growing Russian influence? In an uncomfortable world, we Europeans can no longer sit back and wait for the U.S.A.

Taming the financial markets and winning back democratic control over them is the central condition for creating a new social balance in Germany and Europe.

Climate protection creates sustainability and jobs in the real economy - in construction, in the production of heavy machinery and in systems engineering.
