Causes of flight - how often have you not heard the word in the past few years;
usually combined with the request to take action against these causes.
Actually, an agreement should be reached quickly to do just that.
After all, the refugee crisis has plowed up the political landscapes in Germany and in other European countries like seldom before;
the EU was plunged into a crisis in which the various camps were hostile to one another.
So it is in our own interest to become more involved in the home countries of the refugees and migrants. The latest pictures from the Spanish exclave of Ceuta and daily news of overcrowded boats on their way north from Libya show how big the problem is. North - that is the promise, whether viewed from Central America or Africa, to a life beyond misery and misery. Defense alone does not take the pressure off the boiler.
It is true, of course, that flight has more than just one cause: (civil) war and displacement, climate change, social inequality, economic desperation, demographics. That is why one cannot expect miracles even from a sensible policy of combating the causes. But the old sentence is still true: If the problems are not solved where they arise, they will come to us. The war in Syria showed the force with which this can happen.
