Germany as much as Greece - virtually the whole of Europe, managed to deceive itself when the euro was formed. Everyone feels bruised and wronged by the experience. To blame disciplinarian Germans is as pointless as profligate Greeks. It is half-formed monetary union which is the problem, not the wicked Germans, and it has proved a catastrophe for all involved. The more important question now is whether unwinding it would be an even greater one, or whether something more durable might be salvaged from the wreckage. The geo-political stakes are as important as the economic ones. If Greece is thrown to the wolves, what does that mean for a country with a history of military coups? What does it mean for democracy, and for Europe's already ineffectual role as a buttress against Putin's imperial ambitions? Germany has some big decisions to make.
