During OTL WWII the Low Countries were administered by the Germans directly instead of allowing a native government to be set up (as it did, but democratic in Denmark and the fascist ones in Norway and France).
So my question is it possible for the Netherlands to rather than being controlled by Reichskommissariat Niederlande under Arthur Seyss-Inquart's command, to be governed by a fascist native government led by the native Dutch national socialists, that is, Anton Mussert and NSB? If possible, how would this state look like and what consequences would have both during and after WWII?
Also, what if the Nazis created a (Flemish) civilian administration to govern over the entire territory of Belgium, save those parts annexed. Is it possible? Could it be done with Leopold II's agreement? If so what problems could it cause in post-WWII about conflicts between Flemish and Walloons?
