Global climate change is one of the greatest challenges facing humanity in the twenty-first century.

Look at the history of the printing press, when this was invented what sort of consequences this had. Or industrialization, what sort of consequences that had. Very often, it led to enormous transformational processes within individual societies. And it took awhile until societies learned how to find the right kind of policies to contain this and manage and steer this.

We have [unfriendly policies] here in Europe, too. We have them here in Germany, too. And to take up where the president left off, digitization is in a way a disruptive force, a disruptive technological force that brings about deep-seated change, transformation of a society.

I'm a person who acknowledges reality. I don't get up every morning and ask myself: What would I do differently if I were chancellor in a black-and-yellow (Christian Democrat and Free Democrat) coalition? The SPD (Social Democratic Party) and the (Christian Democrat and Christian Social) Union stand to weaken their own positions if they don't make this coalition a success. And we both want success.

To exclude groups of people because of their faith, this isn't worthy of the free state in which we live. It isn't compatible with our essential values. And its humanly reprehensible, xenophobia, racism, extremism have no place here. We are fighting to ensure that they don't have a place elsewhere either.

I fortunately know very many people, and there are many, many more that I don't know and many politicians who stand up for the same values of democracy of liberal societies, of open societies of respect for the dignity of man.

I'm very pleased this military engagement together with a political road map that we developed, we were able to continue. We want to bring about a political solution there. We worked very closely together [with Barack Obama] on the issue of annexation of Crimea and Russia's attempt to actually conquer Ukraine and actually, they did so, conquer part of the territory. We tried to come to a peaceful settlement here on this.
