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.

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

Iran is the only country in the world that's threatening to erase another country from the map as part of a collective genocide.

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.

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.

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.

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.
