National Socialism is perhaps the pure expression of German Weltanschauung: the militarism and will to expansion as described by Spengler, but it is particular to that state in the middle of Europe surrounded by the great powers of France, Russia and Poland. It's will to dominate represents only one nationalism at the expense of its neighbours and their identities. The notion that the ideology of National Socialism is as universally replicable as philosophy or democracy is patently absurd. Folkishness or socialist economics are, but not the essential belief in a hierarchy of European ethnicities and ingrained militarism with designs of conquest. That would end up in something like the Thirty Years War.
