No, it's not complicated at all. Instead of joining the Danish resistance (who, you may recall, were fighting against the occupying Germans), 10,000 Danes chose to collaborate and fight FOR those very same invaders. Last time I checked, the Soviets never invaded and occupied Denmark, did they? But you seem to think that the Soviets actually posed a greater threat at the time. No offense, but perhaps you are the one who should spend a little more time thinking about this one...
