I have present arguments about the changes that I made: 
 Saying other articles are not relevant ("everyone is wrong but me" kind of) it's not a valid argument under my point of view. If those articles have less active editors is because they have not wrong facts like this. I support this change claiming that The Nazi Germany is another country, today luckly extinted, the same way Russia is not the USSR or the Roman Republic is not Italy. When you check the article (in english) about Alexander II for example, you can see that he was born in the Russian Empire, not just Russia. Sulvester Groth was born in East Germany (GDR), not just "Germany". Same in this case. 
 I don't know why there's a problem with that. ¿Tendentious?
