Chomsky is the very last person I'd go to for any "research", YouTube or not. His relationship with facts is practically non-existent. "USA Bad" and whatever facts need to be cherry-picked, massaged, or ignored, whatever history needs to be rewritten, whatever motives need to be speculated about to support that position is fair game as far as he is concerned. He regularly cites sources while stating something completely different than what they say and his tone frequently suggests this is not even a consideration of fact, but merely an exercise in interpretation as one might treat a work of fiction or artistic work.
