If you're looking for evidence... that the Euro is failing, look no further than this item from today's German News:
Failure of monetary union ruled out The President of the German Federal Bank ("Bundesbank"), Axel Weber, has ruled out the notion that the European monetary union should be declared a failure. The issuing bank in Frankfurt (am Main) stated that it would not entertain such an absurd discussion. The federal Finance Ministry in Berlin had earlier issued a similar statement, that Finance Minister Hans Eichel definitively saw no danger that the economic and currency reform could fail. These statements came in response to a report in the Hamburg-based newsmagazine "Stern" that Eichel and Weber had discussed the topic.
