Europe's military revolution

The creation of the single European currency, a revolutionary innovation for the European Union (EU), has provoked tumultuous debate across the continent and beyond. Yet the EU's plans for a common defence policy have - thus far - attracted less attention. These plans are also of revolutionary significance because they could, in the long run, transform the nature of the European Union, its relations with other parts of the world and, in particular, the shape of transatlantic relations.
