The French and Dutch referendum votes against the European constitutional treaty caused many Europeans to be alarmed for European unity itself. This was called the biggest reversal for Europe in fifty years, a revolt against economic reform putting the euro in jeopardy, a “lurch to the left,” a repudiation of Europe’s modernizing elites, the beginning of the end for the European Union. “We who lead Europe have lost the power to make Europeans proud of themselves,” said Jean-Claude Juncker, Luxembourg’s prime minister and current holder of the European presidency.

The French and the Dutch have done the European Union a service by bringing it on now. A Europe of twenty-five members (not to speak of a potential thirty-five, or more) is too big to function as the Europe of Six, Twelve, and even Fifteen has been able to function. It represents a radical break from the EU as it has existed.
