MUNICH – French Prime Minister Manuel Valls and his Italian counterpart, Matteo Renzi, have declared – or at least insinuated – that they will not comply with the fiscal compact to which all of the eurozone’s member countries agreed in 2012; instead, they intend to run up fresh debts. Their stance highlights a fundamental flaw in the structure of the European Monetary Union – one that Europe’s leaders must recognize and address before it is too late.
