The goal of European unification can only be achieved if everyone participates, perhaps with exceptions in some areas. Not all countries are part of monetary union, and not all are in the Schengen area. But the fundamental goal should be to keep everyone on board.

If we want to make Europe stronger, then each country first has to ensure that it becomes stronger itself. This applies to Italy and France, and it applies to Germany as well. Subsequently, we in Europe need to discuss how we can improve the community. That is the correct order.

We know that the abilities of European Union member states are not infinite. As such, it makes little sense for us to criticize each other.All of us accepted Sweden's decision to introduce border controls too. And that is a country that was for decades the most open to immigration.

Treaties exist so that they will be adhered to. It only serves to strengthen euroskepticism when we constantly make promises and reach agreements that we do not adhere to.

It has been clear for some time now that we have to do more for domestic and external security. I am prepared for that.

History shows us a lot of things. It shows why the Lord's Prayer includes the supplication: "And lead us not into temptation." In my day, dissertations were still written by hand, or drummed out with a typewriter. In the past, you had to round up the literature, find the books and find the passages. Nowadays you click on Wikipedia or Google and you have everything you need. This probably makes it more difficult to resist temptation.

During the centuries-long process of Reformation and Enlightenment, Christian churches had to accept some things they didn't like. Islam will have to do the same; otherwise it isn't part of Europe.
