The French have ‘closed’ their border with Italy on the Côte d’Azur in defiance of the Schengen Agreement, which guarantees free movement within member nations. They are rigorously checking trains, cars and even footpaths across the mountains, and sending any illegal migrants back to Italy; they say they have sent back 6,000 this year. The justification is simple: the Italians are failing to identify these people and distinguish economic migrants from refugees. Who can argue with that? The Austrians are doing the same at the Brenner Pass in the Alps.
