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.

It is clear that several countries, in the Balkans for example, need to be considered countries of safe origin. But others like, in my opinion, Eritrea, undoubtedly need to be considered a country of origin with a valid claim to asylum. And with a third group of states, like Nigeria for example, each individual case needs to be evaluated. Then there are also very controversial cases like Afghanistan. In any case, united European action is needed. This argument for Europeanization may sound utopian, but there is no alternative.

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.

The route for the refugees currently goes through Greece and the Balkans or through Italy; if there were a crisis in north-eastern Europe, Poland might just as well be affected. In this case we are dealing with mechanisms that we do not control. We need to change that.

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 On the other hand, we should scrutinize the now completely outdated principle that only the migrants' first country of arrival should be burdened with their registration as well as with the process of sorting out who has the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.

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.

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.
