The EU is a community of values, not military buildups.

I believe that dignified work is a value in itself.

The racist rhetoric that extends all the way to the top of the AfD shows that one must assume that an attitude is prevalent - not just in the grassroots, but also among party leadership - that is not consistent with the basic values reflected in our constitution.

For German Social Democracy, Europe is vital to the national interest.

We're at a historical juncture: A growing number of people are declaring what has been achieved over the past decades in Europe to be wrong. They want to return to the nation-state. Sometimes there is even a blood and soil rhetoric that for me is starkly reminiscent of the interwar years of the past century, whose demons we are still all too familiar with.

Britain, Europe's second largest economy, a member of the G-7 and the UN Security Council, wants to leave the EU. That weakens us and it weakens Britain.

The Social Democrats have to listen to people who are attracted to the AfD party. That isn't a mistake at all. You can also win them back. Of course, there are a lot of angry voters who are ideologically charged. But there are also a lot of quieter voters who plan on voting AfD to send a message. We can never give up on them.
