I'd say rather than emotional he has the usual academic thing of being up in one specialist area - in this case US imperialism and not up on another speciality like Russia's history of invasion, expansion and the like.
Its my poor wording to blame - when i said emotional i was referring rather to the commenter who attributed Chomsky position to taking sides.
I agree its well thought position. As much as I disagree with him on many matters, he is absolutely right here. Besides being right, it takes immense courage to go against mainstream (which he apparently did all his life) and that’s something i can’t avoid admiring.
