One answer — an answer that makes more sense than almost anyone in Europe is willing to admit — would be to break up the euro, Europe’s common currency. Europe wouldn’t be in this fix if Greece still had its drachma, Spain its peseta, Ireland its punt, and so on, because Greece and Spain would have what they now lack: a quick way to restore cost-competitiveness and boost exports, namely devaluation.

As a counterpoint to Ireland’s sad story, consider the case of Iceland, which was ground zero for the financial crisis but was able to respond by devaluing its currency, the krona (and also had the courage to let its banks fail and default on their debts). Sure enough, Iceland is experiencing the recovery Ireland was supposed to have, but hasn’t.

Yet breaking up the euro would be highly disruptive, and would also represent a huge defeat for the “European project,” the long-run effort to promote peace and democracy through closer integration. Is there another way? Yes, there is — and the Germans have shown how that way can work. Unfortunately, they don’t understand the lessons of their own experience.
