No one should ever apologize for other's ignorance. Your works are highly creative, and very obviously you've done a fair bit of research before drawing that piece.



Anyone who knows even an inkling of history should have known the symbols on their uniform were of the Wermacht, not even remotely Nazi. Not ALL Germans were Nazis, and anyone who is so afraid to make such a connection should stop.



Next thing you know, we can't draw members of the modern Iraq army, because they're 'middle-eastern badguys' and therefore, 'terrorists'?



It is this sort of ignorance and fear that promotes stereotypes and worse, radical thinking, which people like the Nazis and even ISIS thrive on.



So in fact, while I understand that some people may be offended, and you're just apologizing for them, it saddens me to know that internet society has been reduced to this. Your works are great man, no one should tell you otherwise!
