If anyone thinks that Hitler and his Nazi inner circle managed to take over most of Europe by themselves, let us recommend the Military Channel's Nazi Collaborators. The 13-part series ran last year on the network and has just come out on DVD.
After the Allied victory in WWII, there was a concerted effort to hide the choices made by people who decided that cooperating with an imperial Germany was smarter or easier than resisting the invaders. Lots of folks decided it was easier to act like the Nazis were outliers rather than a force that found willing collaborators wherever they went.
Nazi Collaborators rounds up an impressive (or depressing) list of Nazi supporters in Poland, France, Latvia, Croatia, Northern Ireland, Jerusalem, Greece, Holland and Finland. Of the hundreds of hours of WWII documentaries created to fill airtime on the world's history- and military-themed cable channels, this series is one of the few that tells compelling stories that haven't been well documented before.
