The shadow of an exit of Greece from the euro zone takes on ever clearer shape, repeated apparently final attempts to reach a deal are starting to make the whole process look ridiculous. There is an ever greater number of people who feel as if the Greek government is giving them the run-around.

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.

The truth is that we have long had a multi-track Europe with very different objectives. The traditional differences between the north and the south in fiscal and economic policy are far less problematic than those that exist between Eastern and Western Europe. In the south and east, China is steadily gaining more influence, such that a few EU member states no longer dare to make decisions that run counter to Chinese interests. You see it everywhere: China is the only country in the world that has a real geopolitical strategy.

I hope Gunter Grass will continue helping the SPD in campaigns and that he will otherwise remain with us as a provocative literary figure, as well.

Turkey is currently seeking to make itself more independent from Europe and is turning to the east. Is that in our interest?

It's a difficult conflict to endure, and it leads to necessary disputes and debates.
