How about America?
You may claim that Hollywood would never go for it, but aside from aliens, Hollywood does go for it more often than not. To an extent americans no longer accept that anyone except other americans could ever pose a threat to them. How many evil cia/nsa/fbi stories can you name just off the top of your head? And once we get into how outsiders view America, we start getting into a smorgasboard of unsavory characteristics; real and imagined.
To beat the Nazis the Americans will have to sharpen their act.
1) Compared with well dressed storm troopers you average US marine looks down right sloppy. If you look casual no one thinks that you have the credibility to take over the world.
2) The government needs to invest more in wacky science. Intelligent design is a good place to start, but too many US programs are far too sensible.
3) Hollywood needs to pull its weight. As the dominant film industry it can play an influent role in making Americans look cool villains. No many nice guys, Dreamworks!
Of course the Nazis still have an advantage in they are in the past so to speak. They don't have the risk that some muppet will go and spoil their hard created image. Think how much credibility they would have if Ronald Reagan or Sarah Palin had been able to take over the Third Reich?
