Right now the German Constitutional Court will rule on September 7 on whether the original Greek bailout and the Portuguese and Irish bailouts were unconstitutional. Merkel's own party, the CDU, is also not behind her in the deal that was brokered in July about the second Greek bailout. If that wasn't enough trouble, Slovakia, Austria, the Netherlands, and Finland all want collateral for their loans to Greece, giving certain creditors preference over othes.
This is no way for the European Union to survive.
