Yes, I thought that last paragraph of Cockburn's was odd. Like how it was odd for that Polish-American group leader to falsely say Rahm Emanuel was an Israeli citizen and had been in the Israeli army.
I caught Hitchens on a morning CSPAN call-in show not too long ago and he was talking about the Israeli-Palestinian conflict when a caller asked about "the Jews" and the media in a subtle, sinister way and Hitchens did a great job of making the point you're making.
You would think Cockburn would know better. Maybe he's just seeing what sort of a reaction he'd get, for whatever reason. Even that would be strange.
