Heh.  Nothing of the sort.  I just think there's a bit of history missing here.  Either Russian Ashkenazim were adopted into the Bukharan "fold", so to speak, which I would regard as "normal" and "halakhically proper", or the Bukharans, for whatever reason, set about Russifying their surnames.  In either case, whatever happened seems me worthy of mention.  The other possibility is that the people being tagged as "Bukharan Jews" are not actually Bukharan, but rather Ashkenazim who never felt obliged by halakha (viz. the situation in .il) to integrate into the local community, and are, therefore, being inaccurately tagged as "Bukharan", rather than as "Jews from Uzbekistan".  No witch hunt, just a request for clarification.  I do my best to keep my misgivings about what I perceive as an Ashkenazi desire for hegemony out of my editorial interests on Wikipedia.  Kol tov, talk
