FRANKFURT – For many European leaders, the eurozone crisis demonstrates the need for “more Europe,” the final aim being to create a full-fledged political union. Given the continent’s history of war and ideological division, and today’s challenges posed by globalization, a peaceful, prosperous, and united Europe that wields influence abroad is surely a desirable goal. But major disagreements about how to achieve that goal remain.
Historically, monetary union was regarded as the route to political union. In the 1950’s, the French economist Jacques Rueff, a close adviser to Charles de Gaulle, argued that “L’Europe se fera par la monnaie, ou ne se fera pas” (Europe will be made through the currency, or it will not be made). Germany’s President Richard von Weizsäcker echoed this view almost a half-century later, declaring that only via a single currency would Europeans achieve a common foreign policy. More recently, German Chancellor Angela Merkel asserted that “if the euro fails, Europe will fail.”
