If we want to defeat Islamic State, we first have to arrive at a cease-fire agreement in Syria. Once that has been achieved, an anti-IS coalition can be assembled, including Russia, Saudi Arabia and Iran. That, however, will be significantly more difficult in the wake of Turkey's downing of the Russian plane.

People who work hard for their money cannot be placed in a worse position that those who allow their money to work for them.

France is ready for a European revolution and it is Germany that is pulling the brakes. For a long time, it was the other way around. You don't have to agree with the details of every single one of Emmanuel Macron's suggestions, but he's right about the idea of a new foundation of Europe. Europe's Social Democrats have long demanded this. If we really want to, we can create a different, better Europe in the coming years.

We need a big debate in society about how we are going to shape Europe and tame capitalism. A government must provide direction and make concrete proposals. It is one of Angela Merkel's biggest failings that she doesn't do this.

We need economic growth in Europe and we need to find a solution for the excessive interest rates that are making it difficult for many countries to get their own debt under control.

We need to roll back precarious employment models. Temporary and limited contracts were initially seen as a way of introducing more flexibility so as to bridge periods of need in certain phases of production. Some employers have taken advantage of the model to push down wages. In general, we must strive for equal pay for equal work.

Trump has a clear goal: the division of Europe and the destruction of the European domestic market. The fact that Brexit propagandist Nigel Farage was the first European he received in his tower speaks volumes. That is why we must strengthen the European domestic market and work even more closely together in Europe. That is absolutely compulsory for Germany.
