UN Watch has the whole story and timeline for how Richard Falk posted the cartoon (detail above), then denied posting it, then deleted it, then apologized for "unintentionally" posting it. You see, he would "never, ever" do anything as awful as conflating hatred of Israel with the hatred of Jews. Never. So egregious is Falk's behavior that the US has endorsed calls to fire Falk from his UN Rapporteur for Palestine position which was recently extended for another three years. But you can't get rid of the guy:
"UN Watch salutes the US government for echoing our call for Richard Falk, the UN Human Rights Council’s expert on Palestine, to be fired. The US statement speaks of registering a protest with the UN. Only the 47-nation council can remove him, however, and the majority of that body has always embraced Falk. These 47 could have fired him in March, after Falk was castigated for his 9/11 conspiracies by UN Secretary-General Ban Ki-moon. Instead, they reportedly renewed his mandate for another three years, without objection. Besides, the council doesn’t meet until September.
"So who can take real action here? Clearly not Mr. Ban. On the contrary, Falk has attack him with impunity, recently posting a blog about the “Shameless Secretary-General.” No one in the UN human rights system objected, not even the NGOs." More here.
** I hope Mr. Falk isn't offended by my homing in on his schnozz. Any anti-Semitic implications were sincerely unintended. I was actually thinking of Pinocchio.
