Is Fullmetal Alchemist based on Nazi Germany? It may be because I'm Jewish (yes, Madara is Jewish), but I couldn't help but noticing the similarities between Fullmetal Alchemist to the German Nazi regime.


German names (Edward, Alphonse, Olivier, Bradley)
A Fuhrer
"Dogs of the Army"
Very militarized
Blond hair and blue eyes
Extermination (Ishvals)
War on multiple fronts
Human experimentation
An obsession with the occult among high ranking officials


Is it just me? Or is there a connection? Is there some written reference to that? Has the mangaka said anything about it?
The FMA Wiki states that:


  When creating the fictional world of Fullmetal Alchemist, Arakawa was inspired after reading about Europe during the Industrial Revolution period; she was amazed by how different the people from different countries were, in terms of their culture, architecture and clothes. She was especially interested in England during this period and "added to it her own original flavor to turn it into a fantasy world".  


"Fullmetal Alchemist the Movie: Conqueror of Shamballa" — the movie that follows the first anime series — is set in 1923 Germany, and depicts the beginning of the Nazi Party within German politics, being only an extremist group at that point. 

Other than that, I know of no such inspirations. But it may well be that Arakawa has said something more concrete about that.
