If you want to say Germany under the Nazis had de facto rather than de jure socialism, that's fine, but the Nazis were socialists. You've read my reasoning. The Social Democratic Labor Party has ruled Sweden for most of the last century. They never nationalized the means of production. The SDLP is considered a socialist party.
You're insisting on a very narrow definition of "nationalized," anyway. Hitler's Germany was a police state. There was no habeas corpus. There was no appeal to an arrest by the Gestapo. You don't think this atmosphere of terror influenced business decision making? Saying the Nazis didn't "nationalize" the means of production is sort of like saying the mob didn't control the Dune's Casino because an attorney's name was on the deed.
I've read the Rise and Fall of the Third Reich, by the way.
As to your logic, I don't find any. You seem to be stuck reasoning that because two different types of nation states are both powerful, they must be the same. You ignore that they engage in entirely different nation building and social engineering--one nationalizing all land and factories and inculcating into its' citizens the world view that all are equal and that nation states and governments will ultimately dissolve, and the other raising a race and its' historic symbols and institutions to worship of the eternal state while inculcating its' citizens with the idea that they are superior to all other races, and nationalizing only actual people as slaves to serve the master race.
Others in this thread have basically agreed at this point and have just worked out fine details, but you are a stubborn one Tribune. Why do you suppose Hitler put 90% of his armies on the Eastern Front and only 10% on the Western? Could it have been that the ruling class of Germany thought that Britain and the United States would ultimately see the wisdom of joining Germany in fighting communism, all three countries at that time practicing some brand of fascism, the latter two admittedly very mild.
