The very fact, that "history has marked him", as Mr. Pfeffer put it, is what gives Mr. Grass' opinion some authenticity. He knows from experience how easily one could get involved with the Nazi regime, which makes him - an intellectual, a man of letters - capable of seeing things from a broader perspective. Grass tried to fuel a debate about the rising tensions between Israel and Iran, and what Germany's part in this conflict is, understanding that Germany is the world's third largest exporter of weapons, which are - in the case of Israel's acquisition of several submarines - partly financed by the German tax payers. It should at least be allowed to discuss this openly. Sadly, the widespread reaction of German media is to condemn Grass as anti-Semite (which he is clearly not, as even the poem itself shows), instead of dealing with the points he made in an differentiated way. Both quoted examples in the article perfectly illustrate this.
