Besides Germany, the only countries that don't have speed limits are places like Nepal, where road conditions are so bad that a limit would be beside the point. In other words, it's a little crazy that this is even a topic for debate in Germany.

We need a greening of globalisation.

It is clear that Germany needs a foreign policy in which we jointly define European interests. Thus far, we have often defined European values, but we have been much too weak in defining mutual interests. To preempt any possible misunderstandings: We cannot give short shrift to our values of freedom, democracy and human rights.

Those who reject integration programs in the long term have as little right to stay in Germany as a hate preacher paid from abroad in a mosque.

However, I have a low opinion of people with narrow political horizons. Someone who talks about the environment and knows nothing about economics can make as many mistakes as someone who does the opposite.

What we have at present is a system of loss socialism. Whatever goes wrong is shouldered by the general public and anything that works is privatised. Worshippers of market freedom have suspended the most important economic principle: Risk and liability go hand in hand.

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.
