There is a proposal to divide the currency zone into a north and a south euro. There is also the idea of setting up a core monetary union in the middle of Europe. I disapprove of these debates. Instead, we should devote all of our efforts to supplementing the monetary union with a political union.

I am for secret, dark debates.

Without the Turkey agreement, tens of thousands of refugees would still be stuck in Greece. The Commission presented proposals for securing Europe's external borders early on, but they languished in the Council for months. As you can see, the Commission isn't asleep. Oftentimes it has to wake up the others.

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.

I put my money on Brexit. The EU Financial Stability Commissioner, Jonathan Hill from Britain, still owes me a pound.

Anyone who believes that the eternal question of war and peace in Europe is no longer there risks being deeply mistaken.

I have no doubt that the U.S., even under Trump, will stick to the mutual defense commitment in the NATO treaty in the event of an emergency. Trump described NATO as being obsolete during his election campaign, but he made clear afterward that he considers the alliance to be an indispensable necessity.
