Unfortunately, Chomsky took the literal exact opposite view of the Ukrainian War than he did the Vietnam War - that the imperializing power in Ukraine deserves some concessions, as a treat.

Chomsky definitely had serious contributions to make to political thought, but he could be intensely campist in his positions on international affairs. "If the West does it, it's bad; if anyone else does it, it's understandable or the West made them do it" kind of thinking.

To my knowledge, he never advocated for the kind of brutal domestic institutions the way tankies do, and was opposed to that thinking - so no horseshoe (or stethoscope) theory, simply a view of international politics which was consistent in team colors, but inconsistent in principles.
