In the beginning of her essay, Hannah Arendt explains that of the four countries almost completely immune to anti-Semitism- Denmark, Sweden, Italy, and Bulgaria Denmark challenged its German masters directly. As soon as the German authorities talked about forcing Jews to wear the yellow badge,' the Danes replied that all Danish citizens, including the King, would be wearing it the next day if the policy were carried out. In addition, all Danish government officials threatened 舌は the German authorities with their immediate resignation if the Germans started to implement any anti-Jewish actions. The following excerpt from Eicbmann in Jerusatem shows how the Danes sabotaged the German plan to carry out the mass extermination of the Jews. only 2タカ人の What happened then was truly amazing; compared with what took place in other European countries, everything went topsy-turvey.

Thereupon. the Danish workers decided that they could help a bit in hurrying things そのうえに up: riots broke out in Danish shipyards, where the dock workers refused to repair German ships and then went on strike.
