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.

Politics is a dynamic process. When I was a young man in the 1970s, Yasser Arafat had just perpetrated various terrorist attacks. Just a few years later, after I had entered European Parliament, the same Yasser Arafat was given the Nobel Peace Prize.

We are in the middle of a tough, ideological conflict that is being waged across the entire continent. On the one side are those who say that global challenges like migration and terror cannot be met with national parochialism. On the other side are those who would like to see a renaissance of the nation-state.

For many people, politics in Brussels and Strasbourg might as well be happening on another planet.

The membership survey was a great moment for inner-party democracy. We can't go back, nor do we want to. Our members are pouring their hearts into this campaign. But people don't join the Social Democrats party just to put up posters. They join because they want to help steer the party.

We are seeing now that without the contribution of the Social Democrats, Germany cannot be governed. We are a proud and self-confident party. We should now act based on that pride, and not out of fear.

The dangerous glorification of the nation state, and the baiting of minorities that goes along with it, releases an anti-democratic energy.
