Can Schengen survive? CEPS Commentary, 14 December 2015

Against the background of Europe's refugee crisis, not to mention last month's terrorist attacks in Paris, Daniel Gros acknowledges in this Commentary that the core principle of a "Europe without borders" has come under serious attack. He exhorts member states to realise that they can be more secure without sacrificing liberty if they create a common institution to guard the external borders and reinforce the existing framework for internal security.
