In reply to your message: I in no way question the use of the ENGLISH term "Russian Far East."  Rather, I am saying that correct RUSSIAN translation for it is "Дальний Восток."  I am not sure how "familiar to anglophones" criteria can be used here, since presumably anglophones are not going to be familiar with either of the Russian terms.  It is my understanding (incorrect?) that the purpose of providing the Russian term is to inform the reader how the entity is actually called in Russian, not to translate back the English term.  Note that the Russian name for "Joseph Stalin" is given in WP as "Иосиф Сталин" not as "Джозеф Сталин," even though the latter version would be more familiar to the anglophones.
