Well he's German isn't he.
Every time I talk to a German about anything nuclear, they think the apocalypse is near.
He probably thinks that a derailed radwaste train would trigger a world-wide nuclear holocaust.
(Don't want to insult the many rational Germans on this board. But I'm married to a German and the undercurrent of angst and guilt in German culture has become a pet peeve of mine.)
I for one prefer our culture of guilt and angst over our culture of hypertrophic nationalism after the founding of the Kaiserreich.
The generation most shocked by Grass is the generation of my parents. For them he was a moral writer, a writer that put the finger on the wound that Germany had not completely managed to get the nazis's victims their deserved justice and that brown henchmen and opportunists ended back in power in Germany after the war. It was almost unbearable for them to see his own hypocritical position regarding his own biography after he publicly flogged others for having been in the Wehrmacht and the NSDAP.
This just happens to add insult to injury. He seems eager to fulfill every stereotype of the caught salon antisemite, including the evil media conspiring against him. Which makes me wonder who he suspects as the instigators.
