All the nonsense with Zionism being like Nazism is pure Soviet agitprop from the Dept. of Scientitic Anti-Zionism. The USSR was pro-Israel when it looked like socialist Zionist parties would get the upper hand--kibbutzim and all that--but did a sharp turn with a reductionist and simplistic "if we don't approve of it, it is fascist" thinking. Some tenets? Jews aren't native to the area, Zionism is colonialism, Jews are outside oppressors, Israel is an imperialist state. (Oh, when I say "department" I mean academic division on par with the dept. of mathematics, the dept. of chemistry and physics, the department of Germanic languages and literatures, with a dept. chair, faculty, students, and conferences and tenure review. Not like Dombrovsky's "Dept. of Unnecessary Things"--even if it would fit there.)
Mahmoud Abbas wrote his dissertation in that field, basically, at a Soviet-sponsored "liberation" university. The thinking became widespread among some Western anti-imperialist and anti-colonialist scholars who had no problem with Soviet colonialism and imperialism, and scant concern with the PRC's imperialism and colonialism--the power of agitprop and if you stand for nothing you'll fall for anything (with Igel's corollary, "and having fallen once for some something, you'll stick with that something and make it your everything".) And it lives on today in Trafalgar Square and other venues.
Yes, Americans and Westerners in general have been falling for Russian propaganda for a long, long time. At least we Westerners have company.
