By the time the Nazis invaded Norway that country had only been independent for three decades, recent enough that Nora's father would have still remembered when the Swedes left. Despite their talk of "racial unity" and "master race", they are just more foreign conquerors. Nora joined the Resistance because she knew that a country which accepted foreign invasion was dead, but that one which resisted could rise again. The countries conquered by the Hitlerites would rise again! Norway would rise again!
