EUROPE - Mario Draghi essentially failed. The outgoing president of the European Central Bank was brave, tenacious and skilful. He secured consent from Berlin for a rescue of the disintegrating Italian and Spanish debt markets in 2012. In that sense, he saved the euro. But for all his accomplishments he does not bequeath a safely-constructed monetary union to Christine Lagarde, his unlucky successor. The task was too great. The damage from the Trichet dark age and austerity overkill ran too deep. German and North European refusal to countenance fiscal union - albeit for valid constitutional reasons - leaves the euro an orphan currency with no pan-EMU budgetary mechanisms to counter economic shocks.
