In the west, it's called World War 2. For Russians, this is called the Great Patriotic War...but does this only refer to the Eastern European Front 1941 Jun 22 to 1945 May 9?
Is the Battle of Britain, for example, considered part of the Great Patriotic War? What about the Japanese Pacific theater? Do Russians have a term for WW2 that encompasses the greater global conflict?
Or, even closer, what about the Winter War (first war with Finland in 1939)? Or something like the Battle of Lake Khasan that was at the Far East fighting the Japanese in 1938? Are these considered part of the Great Patriotic War?
(sorry I have no idea what tag to use so I just used "nouns")
