Having been in Germany since the re-unification and meeting more than a few Nationalists there; I have no doubt that their intent is to create a fourth Reich. They are clear and plain spoken about this matter. And when you speak to ordinary people, the auslandern (foreigners) are perceived as the root of the problem.
One could reasonably argue that the muslim foreigners *are* the root of the problem. Doesn't mean Germany will go blame the Jews, nor firing up the furnaces again. There is a big difference between being concerned what's up within the country, which demographic is responsible, and militarizing the whole country for racially based conquest. A *BIG* difference. Don't get carried away.
