I'm sure that if the internet had been around in 1940, there would have been "Frenchmen" and "Norwegians" posting that their "German brothers" were really only bringing progress and prosperity, and that they should be welcomed with open arms.
Quisling: A word Norwegians are not very proud of having given to the world: it derives from Vidkun Quisling (1887-1945), a Norwegian politician who collaborated with the Nazis during World War II. He established his name as a synonym for "traitor", someone who collaborates with the invaders of his country, especially by serving in a puppet government. Quisling was found guilty of high treason in 1945, and was executed by firing squad on the 24th October 1945.
