Authorities in France temporarily blocked trains from Italy in an attempt to stop north African migrants from entering the country. Trains were stopped at the border for hours – prompting Italy to launch an official complaint with France. Services were later resumed. Italy has angered France by giving temporary resident permits to thousands of Tunisian migrants. The permits allow them to travel freely in many European countries.
If National Sovereignty means anything, it means France can protect its borders. Italy is simply transporting the problem westwards.
