This question has come up several times on shows like Dancing With the Stars. There’s a Russian pro (Anna Trebunskaya), Ukraine (Maksim Chmerkovskiy), an Albanian (Tony Dovolani). They all were children under the Soviet Bloc and trained as dancers under the famous Soviet coaching system.
Was Russian a required second language for all members of the Soviet Bloc? Were children taught to read & write Russian in school while the Soviet Bloc existed?
What about now? The countries that are still aligned with Russia? Would children there be taught Russian?
So, could these former Soviet Bloc Dancers swap stories in Russian or write emails to each other in Russian?
This season supermodel Petra Nemcova (Czech) is on the show and she is partnered with Dmitry Chaplin (Russian). Maybe their rehearsals will be in Russian?
