It's not I suppose. But just because Germany lost the war doesn't suddenly absolve the people of their crimes. It took a nation to do what they did, not an army. When Goebbels planted the seed in Hitler's head and denounced the jew, and every other German citizen then took it upon themselves to carry out Kristallnacht, and then help round them up into the ghettos, screaming at them, spitting at them, throwing stones at them, destroying their property etc. and finally help load them on to the trains, then these are the people who burned to ashes. Although the war was over, the punishment was still due.
The essence of propaganda consists in winning people over to an idea so sincerely, so vitally, that in the end they succumb to it utterly and can never again escape from it.
This was the mark of the entire German nation (precluding German jews of course).
