The message that "we can't take in everybody" is imperative. At the same time, the decision as to who has a right to asylum needs to be made in Brussels.

And a united Europe will also manage to send hundreds of thousands of migrants, who don't have the right to asylum, back to their homelands. Though that, given the number of flights necessary, would be of a scale reminiscent of the Berlin Airlift.

But joint pressure from states like Germany, Italy and France could mean a move in this direction. Because something very fundamental is on the line: freedom of movement. I can't think of any common market that could function without it.

But it could be that we, as early as spring, will need to embark on a new policy in order to save one of the cornerstones of European politics: personal freedom of movement.

We cannot treat people with a right to asylum the same way as people from a safe country. They need to be sent back. That is, from our perspective, completely clear. On the other hand, we should scrutinize the now completely outdated principle that only the migrants' first country of arrival should be burdened with their registration as well as with the process of sorting out who has the right to asylum and who needs to be deported.

Let's put it this way: I am confident that Schengen will continue to be defended. And when it comes to repatriations, we have the same opinion.

I'm not particularly optimistic, but I hope that the lack of alternatives will lead to it. I would like to remind you of the fact that before May 2015 there was no overall European agenda on immigration. Nothing, zero. It wasn't until after yet another tragedy in the Mediterranean that, in response to an Italian initiative, (Europe) began thinking about setting policies for the registration of refugees, their distribution or their deportation.
