I can't quite agree with you on Norwegian anti-Semitism. Half of Norway's Jews were killed during WW II. They had little local support, as the Norwegian Jews were descended from German Hanse traders in the late Middle Ages. Accordingly, they have always been considered outsiders, religiously and ethnically. The original Norwegian constitution (1814) even denied citizenship to Jews. Thankfully, Norwegians did defeat a recent attempt at an official ban on Israeli products.
As for occupation, sure the Norwegians didn't like it. That said, 50,000 of them served with the German military in WW II, including 10,000 with the Waffen-SS (Norway officially admits to 7,000 with the SS; the 10,000 number comes from German records). Norway was also the most active particpant in the Lebensborn program: An effort to have local women bear the children of German soldiers.
