Germany's controversial approach to fighting the euro crisis has split the European Union. Some countries are complaining about Berlin's rigid course, while others accuse Chancellor Merkel of betraying the European project. The only thing they can agree on is that the EU needs Germany as a motor if it is to survive. "The more the euro crisis expands into an existential crisis for the European Union, the more critical are other member states about Germany, the largest economy on the continent and the fourth largest worldwide." "This is all about Germany, and it's all about the end of the German appetite for writing checks to the periphery of Europe."
