I don't anything on etymology but Luftwaffe bombed the cities of the Soviet Union from the air. 
 interesting do you have anything else about that? 
 Russian Federation is a country that is in Eastern Europe and in North Asia. It is the largest country in the world by land area. From 1923 to 1991, it used to be part of the Soviet Union. 
 Thank you so much for all of your help
