I have another explanation [of Brexit]: In its 43 years of EU membership, Britain has never been able to decide whether it wants to fully or only partially belong to the EU.

You can't deepen the European Union against the wishes of the European countries.

We can't completely rely on the aberrations of history to explain today's European necessities. Future-related issues are no less pressing.

Trump is a partner for us who cannot be easily categorized. Putting it in the noblest way possible, his understanding of politics is a little different from ours here in Europe. The way he acts forces us Europeans to take on a new responsibility. We are not standing with our backs up against the wall, but, to put it as pithily as the German chancellor has: We can no longer rely on the U.S. the way we could in the past.

I haven't yet given everything: I am still full of energy. But I wanted to make it clear that I don't have to make unwarranted concessions to national governments or to parliament. I want to avoid the impression that I am doing things just to ensure that I am re-elected. That's not the case. I have had my career.

We do not attract Russian money to Luxembourg with high interest rates.

In the end, the British didn't vote to leave because of the euro. They're not even members of the currency union. Even the refugee crisis hardly affected the country.
