Let's try to understand this here: Suppose, all of a sudden, a new President comes in to office and announces that his predecessors had engaged in a fraudulent scheme to hide the total US debt off the books completely. The US government now lacks the funds to pay off the true debt that was hidden. In response, China, to whom we owe the debt, comes in the dark of night, removes the President in the middle of his term by dictat, and replaces him with the guy who engaged in the financial fraud in the first place. All without holding an election. Now, replace "United States" with Greece, and "China" with Germany, and I think you'll see the epithet of Nazi, though politically inaccurate, is the result of a justifiable anger.
Nobody forced the Greeks to elect these corrupt politicians and nobody forced them to borrow the money.
The Greek people should be angry at their own, not the Germans.
