Because the present Israeli leadership simply can't swallow people voicing opinions that deviate from their established dogma. I know it's difficult to believe, that they would want us believe that occupying a foreign land for 45 years now, with no end in sight, and against overwhelming international opinion, is the reasonable act of a resonable, 'democratic' (
) government (maybe they mean 'democratic' in the sense the word was used in Alabama until the 50s and in South Africa until the 90s.... meaning glaringly undemocratic for anybody who hasn't been brainwashed by Orwelian level "newspeak").
Former SS member, who hid it all his life,
Wonderful and constructive way to refer to a 17 year old teen who, when drafted as all German kids were, chose to serve in an elite tank unit while his country was fighting a losing war. You make it sound like if he had eagerly volunteered for the cause of Ahnenerbe.
and as far as I know (and I can be wrong) wasn't in Israel before,
Yes, you are wrong. Grass has been in Israel repeatedly these last decades, at least three of them invited to lecture in Israeli Universities. He has spoken in favour of Israel, many times, and has been for years one of the most outspoken voices in Germany against forgetfulness or down-playing of the Nazi horror. That is precisely what the hardliners in Israel can't fathom, that this is a moral leader against Nazism expressing dissent. If he was a far right freak, he would mostly have been ignored.
tries to enter it days after
No, Grass hasn't tried to enter Israel. No need for someone to be on your doorstep for a country to issue a 'persona nongrata' statement. Those things don't work that way.
an antisemetic poem (and it wasn't Israel criticism, it was just Antisemitic). It's nothing but a provocation.
The resource to labeling as Antisemitic anyone who dares critizice the established dogma of the Israeli intelligentsia is so expected, so weak an argument, that Grass actually included it in his poem. The automatic, kneejerk, manner in which that accusation is brougth out, actually is solid proof that Grass is onto something. Now, if he hadn't immediately been accused of Antisemitism, if his opinion had been received as just that, a freely expressed critical view on Netanyahu's policies, you would have an argument that maybe Grass had exaggerated. On the contrary, your reaction mostly proves his point.
In the end, the lie to accusations of Antisemitism has been given by Israelis themselves. People like Gideon Levy, on the pages of Haaretz, and several other well known Israeli writers and intellectuals, have come out in defence of Grass. But, of course, those truly democratic citizens of Israel who really want to move things forward with peace and justice for all, they are only self-hating Jews, aren't they?
Just a few weeks ago, David Grossman, who is obviously just another Antisemite, published an opinion column on several of Europe's main newspapers. The details were different, but its core idea was very much online with Grass's poems.
Evil always tries to thrive on the silence of the just. Read Hannah Arendt on that.
