You mean Prussia? At least if you say you're Prussian the same people who equate Germans and Nazi's will think you come from somewhere near the Ukraine.

I also get the feeling most Americans don't equate Germans and Nazis. Though I suppose they might be quick to throw the label around to be mean (especially on forums like this if you're arguing with them).

Personally I think the way Germany has delt with WWII and the holocaust is a model of how other countries should deal with similar things. You acknowledge it, don't gloss over it, but don't let it paralyze you and you return to the world stage.
