I am a champion of trans-Atlantic relations and I do not believe there is any other option available to us than working closely together with America - including Canada. There is no other alliance option, but the same is true for the U.S.

For my generation, the monetary union has always been about forging peace.

Trump knows that he is encountering a complete lack of understanding in Europe, but it's apparent that he's not very impressed by it. My experience, however, has been that American presidents take a greater interest in Europe over the course of their term.

I don't think in national categories. For me it [policy] is about concepts and substance.

We must also take this opportunity to learn from the situation [of Brexit], just as we learned from the refugee and debt crises.

I am for it - not to make a threat, but to make clear that decisions that have been made are applicable law, even if you have voted against it. At issue here is European solidarity, which cannot be a one-way street. The traffic has to move in both directions.
