We agree: Brussels can't regulate everything. I'm driven by something else: There are forces in Europe that want to generally give national policy priority over a common European approach. We have to prevent this.

Following the attacks in Paris, French President François Hollande has a completely different set of concerns. France needs more police, more security personnel and a greater emphasis on integration. He says that security is more important than the Stability Pact.

If we want to defeat Islamic State, we first have to arrive at a cease-fire agreement in Syria. Once that has been achieved, an anti-IS coalition can be assembled, including Russia, Saudi Arabia and Iran. That, however, will be significantly more difficult in the wake of Turkey's downing of the Russian plane.

Trump believes politics is a staged fight. But it is not. Still, clear words are sometimes needed in politics. In that sense, I believe I am better than Mrs. Merkel.

If Merkel has discovered Europe in a beer tent, I can only say: better late than never. Otherwise, it was the height of hypocrisy: The chancellor sat down for a beer with CSU Chairman Horst Seehofer, the man who after the election praised Donald Trump as a very resolute man.

Keeping quiet and letting the others do the talking. That may be Angela Merkel's method, but it's not mine.

We have committed ourselves to pursue joint policies, but then national governments say, "We aren't bound by that." That is a dramatic situation, because solidarity is a basic principle that cannot be had on an à la carte basis. If we have rules that nobody adheres to, then the community will break apart.
