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.

Economically and politically, Germany is extremely stable. There are countries with functioning governments whose institutions don't work. My only concern is about Europe. There's a risk we will run out of time. We have been blessed with a pro-European French president, but we are also approaching the next elections for the European Parliament in 2019, and it will be important for pro-European parties present a credible answer to the anti-Europeans on the left and the right.

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

When you think back today to a time more than 70 years ago when Germany was a terrible place, a place people were afraid of, it is a wonderful development that we have gone from being a terrible place to a place that people dream of.

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.

I am certain that the United States next year, under a new president - regardless whether it's Obama or McCain - will present an ambitious program promoting renewable energies and energy efficiency. Europe could quickly fall behind.
