Indigenous nations are victims of civilizations, not just one civilization but civilizations generally. This is obfuscated by Postcolonialism which epistemologically privileges Islamist imperialists and Arab colonialists over their victims, including the Jews and other indigenous nations of the MENA region. Colonialism and imperialism are not exclusively Western phenomenons but are inherent to civilization generally. Postcolonialism claims to champion victims of colonialism and imperialism while in fact championing colonialists and imperialists from yet another civilization. The Soviet Union claimed to oppose colonialism while engaging systematically in Russian colonialism. The Soviet Union claimed to oppose imperialism while seeking Soviet world rule. The Anti-Jewish pseudoscience inherent in Postcolonialism and in leftwing Anti-Semitism generally is based upon the discriminatory Soviet propaganda discourses of Operation SIG. Leftwing Anti-Semitism is thus imperialist in origin. It is an urgent task for the State of Israel and the Jewish world to expose the Anti-Semitic structure of Operation SIG and how Operation SIG is still maintained and developed by PA intelligence worldwide. Critical theory should champion the experiences of indigenous nations, including the Jews, suffering from imperialism and colonialism of any civilization.
