Hello W.C. (a cunning abrev. he.he)
first of all I find no reason in history or in the movie that could prove Stauffenberg to be a "pseudo" anti facist or a pseudo facist antihero.
Especially not for someone who risked his live to fight the facist.
Secondly: to which historical inaccuracies are you refering to or have you noticed? (German shepherd's such as Blondie have been mixbreeded for the past 60 years so even for Hollywood it would be impossible to find one with a straight back)

Kruska
