Money quote(s):
"This opinion piece addresses the same general concern as that book, updated to today: immigration and borders in Europe. In many ways, after all, at least alongside the sovereign debt crisis in Europe is the startling re-introduction of border controls in Continental Europe, and a call by Sarkozy and Berlusconi for a revision of the famous Schengen agreement removing border controls among twenty-two European states (not including the UK and Ireland)."
Be sure to read the quoted passages from the cited article. One slice of that:
"The Schengen agreements, signed in 1985 and 1990, permit
passport-free travel within 22 continental countries of the European Union (Britain and Ireland are among the exceptions), as well as non-Union signatories. Along with the euro, Schengen is Europe’s symbol, a milestone in its integration — on a continent long hemmed in by nationalism and bureaucracy, an Italian can travel to Paris without showing papers or changing money. And it’s growing: the European Parliament this week voted overwhelmingly to recommend extending Schengen to the European Union’s two newest members, Bulgaria and Romania."
