Well, so much for that:
European nations moved to reverse decades of unfettered travel across the continent when a majority of EU governments agreed the need to reinstate national passport controls amid fears of a flood of immigrants fleeing the upheaval in north Africa.
In a serious blow to one of the cornerstones of a united, integrated Europe, EU interior ministers embarked on a radical revision of the passport-free travel regime known as the Schengen system to allow the 26 participating governments to restore border controls.
It is a fantasy, of course, of very old standing. The great peace of Innocent III was the expression of just such a fantasy—the notion that the Catholic Church was finally in a position to introduce the City of God into the fractious European political arena. That attempt lasted no more than a generation. Why should this one last longer? No effort to unify Europe has ever succeeded. Most have ended in blood.
... the European Union is historically nuts. It reflects neither the will of a single nation-state, nor the will of an Empire, based on the ability of a central political entity to dominate its periphery, nor some form of established European national identity with deep historic roots. Even the Austro-Hungarian Empire had in Austrian power—diminished as it was after 1866—a stable and powerful center. All of European history—all of world history—argues against a federation with no force to back it up and no way to impose its will on member states. ...
The EU is in effect an empty empire. The only national identities up for grabs are the old national identities of the chief nation states of Europe. And no matter how much the EU bureaucrats try to promote a French into a European identity, what do you know? The people just aren’t buying it.
Is it ungracious to say "I told you so" over and over? I fear that it is. But I did.
