Complementing the nation-state as it reaches its limits amid globalization: That is what Europe must offer.

But if you constantly insist only on your own interpretation, it isn't long before it seems patronizing.

It's not attractive at the moment to vouch for the European idea. I still do it, because I believe nothing would be better for our continent.

It was clear to me that the White House's solemn atmosphere would not civilize Trump. But the merciless nepotism with which he conducts politics, in which he places himself and his family above the law, I wouldn't have considered that possible. And on top of that there is this reduction of complex political decisions to 140 characters. When it comes to a U.S. president, I consider the reduction of politics to a tweet to be truly dangerous. Trump is a risk to his country and the entire world.

Political leaders need to formulate long-term EU goals that show: Yes, we want to stay together.

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.

For me, respect is an extremely important political term. Since I began campaigning, it has been at the heart of each of my speeches. Many people have the feeling that politicians aren't paying a sufficient amount of attention to them. And then, when the refugees arrived on top of all problems, there was a feeling: You do everything for them, but nothing for us. This mixture of frustration and fear has led to this reaction. That is why it is so important to show these people: We respect you.
