The exit of Greece from the euro zone by choice or happenstance might have caused ripples but not disaster for the currency union. By contrast, the exit of Spain, with the fourth largest GDP in the euro zone, would be catastrophic, the end of the single currency and perhaps the European Union in its present form. The German government and its austerity allies could not threaten an anti-austerity Spanish government as they did Syriza.
