I am chilled by the realization of how similar circumstances in Europe in 2013 are to those of 100 years ago.

I prefer to concentrate on my task of leading Europe to the success that our citizens expect. We have to look forwards now because what is at stake is what makes Europe Europe.

Here in Brussels, we did everything to accommodate David Cameron's concerns. My collaborators and I personally spent countless days and nights negotiating an agreement that was fair toward the United Kingdom and toward the other 27 Member States. I was then very surprised to see that this settlement played no role whatsoever in the campaign in the United Kingdom. At the same time it is hardly surprising.

In 1913 many believed that there would never again be a war in Europe. The great powers of the continent were so closely intertwined economically that the view was widespread that they could no longer afford to have military confrontations.

I have a plan. It entails leading to a fair deal and relationship with the British. We will be reasonable, but we will also negotiate firmly and without gullibility. I believe we must come to an agreement for the people of Britain and the people on the Continent, but not under exclusively British terms.

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.

Many in Germany are saying that Macron should be helped. That's also how I see it. But Germany cannot solve France's problems. The French president and his government will have to seriously knuckle down in order to pull France out of its slump.
