Quite true.
However, I believe the only aspect of Norwegian resistance the author is interested in is how effectively they protected their Jewish inhabitants. About 99% of Danish Jews survived, while about 1/3 of Norwegian Jews died in the Holocaust.
Denmark was a neutral country occupied by the Germans. Their government generally cooperated with the occupiers, while resisting in some areas such as that of protecting Jews.
Norway was a conquered country, and was treated very differently and more harshly by the Germans. The wartime Norwegians had less ability to resist in the subtle ways the Danes did.
You sort of raise an interesting question...
Would it have been better to surrender like the Danes?
More Norwegian and jewish lives would probably have been spared?
