cosmopolitanism

From cosmopolitan + -ism. The sense referring obliquely to Jewishness comes from the long era in which all Jews lived in the Jewish diaspora because Jews had been banished from the ancient Jewish homeland and no new homeland yet existed. In Soviet use it was rooted in fear of transnationalism generally but took on coded or dogwhistle antisemitic qualities that were not explicitly separable from the generality.
