For example, his treatment of the Cold War. Like many people whose countries fell on the dark side of the Iron Curtain, I am grateful for all that the US did to contain and defeat the Soviet Union. When countries like Poland were oppressed under the communist rule which was in some ways more destructive than the second world war, Chomsky would have liked to let a large chunk of the third world fall under the same yoke just to avoid confrontation and casualties. This is a view that I find dangerous, ignorant and BS.
One could get a much more objective, fuller and clearer picture of things as well as appreciation of the complexities involved by getting an international relations textbook such as International Relations Since 1945 by Kent or a lighter read, The Global Cold War by Westad.
