But anyone who believes that the eternal issue of war and peace in Europe has been permanently laid to rest could be making a monumental error. The demons haven't been banished; they are merely sleeping, as the wars in Bosnia and Kosovo have shown us.

Angela Merkel did the right thing. Her decision and the extraordinary willingness of the German people to take in refugees conveyed an image of Germany that is still having positive repercussions today. Unfortunately, people in Germany are no longer seeing that.

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.

But it is the best thing that we have for bringing the countries of Europe around the same table and for forging compromises so that people here can live in peace, freedom and prosperity. In a world which is growing closer together all the time, we can only survive and influence the rules if we join forces. We will miss the presence of the United Kingdom at this table.

I have changed the focus of the work of my Commission so that we no longer concern ourselves with trivial details and concentrate on the key issues instead. By doing that, we met a large number of the legitimate demands made by the British people. The Commission really did do everything it could to create the conditions for a positive campaign.

The European Union has decades of experience in overcoming crises and has always emerged stronger after.

The problem is: When two governments or institutions in Europe hold differing opinions, it is immediately a crisis.
