Michael Binyon in Politico:
No country is more committed to European integration than Germany. All the grand schemes to bring Europeans together — the single currency, the push for common policies, the abolition of frontier controls within the European Union — have Germany at their heart.
But Berlin’s announcement Sunday that it is to reimpose frontier controls with Austria strikes a deadly blow at of one of the few agreements that has turned these visions into reality — the Schengen treaty, which removed passport controls along thousands of miles of Europe’s frontiers.
Is Schengen now dead? And is this the beginning of the end for an “ever closer union” in Europe?
