You have to let the people vote when it comes to a new constitution.

I'm fully aware that my vision of a European bicameral parliament can't be implemented tomorrow. I'm also not an integration fanatic.

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

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.

In political life, it is extremely difficult to remain loyal to a friendship when constellations of power or interests are in the way.

I still hope that the American system of checks and balances will ultimately prevent this man, Donald Trump, with his erratic political style, from jeopardizing our European security architecture.

Turkey is doing an enormous amount in the refugee question, but it can't continue to pay for everything by itself. That is why we have to talk to Turkey about money.
