Jeff Blankfort has been exposing him for years: https://www.unz.com/article/sf-imc-interview-jeffrey-blankfort-jewish-american-anti-zionist-journalist/

Chomsky wants to believe in the tooth fairy, that the Zionists were really ready to live with the Palestinians. And he, of course, was a Zionist in his youth...

...it’s interesting that while people talk about Edward Said, Chomsky is the one who is revered. Although, obviously Chomsky keeps writing and speaking and writing and speaking. You can’t turn around without another Chomsky book or speech. It’s interesting, whenever I see a Chomsky speech or interview about Iraq, I do a “find” and type in “Israel.” Invariably, the word is not found.
