The economic tide is swinging in favour of the pro-Europeans. Much of the EU has been late to catch the global upswing, but even the weaker economies are starting to benefit. They will gain also from the tough measures taken over the past few years. Further, the conclusion of a successful free-trade pact with the United States would hammer home the message that union can deliver more wealth than individual endeavour. It is also easy to forget the EU's greatest achievement, that of delivering peace to a continent scarred previously by never-ending conflict. Voters have indicated their national identities must remain important. That, however, is no reason to disown the reasoning that created a united Europe.
