But why do you think the Germans initiated WWII in the first place? Again, it was for economic reasons. So as I said, the war was motivated by economics, not morality.
Sure, Hitler tried to make it sound like it was all about creating some sort of utopia with a perfect Aryan race, but we know that was a lie. If we are to take Hitler’s word for it when he attempted to justify his actions, then we would have to believe that he was a devout Christian.
I think that, just as individuals can be motivated by their ideals-- including ideals that most of us would find abhorrent, such as the ideal of a racially pure society – so too can the leaders of nations have idealistic considerations that override sheerly pragmatic ones (i.e., true fanatics do exist). The expulsion of the Jews from Spain, for example, is believed to have been driven largely by an ideology of maintaining a purity of the faith – and, by some accounts, the expulsion of the Jews from Spain proved to be economically disastrous.
My impression is that historians often over-ascribe pragmatic motivations to the decisions of world leaders when, in fact, genuine idealists do exist (again, I use “idealist” in a morally neutral sense of the word; the Ayatalloh Khomeini would be another idealist or, if you prefer, “fanatic” or “ideologue”; such individuals are indeed dangerous, because an appeal to common sense may not sway them). Everything I’ve read about Hitler leads me to believe that he actually believed in the ideology he was espousing, just as he actually
did draw inspiration from the operas of Wagner (Lohengrin, for example), which made him seem quixotic in the eyes of his associates (they suffered through many a performance). He had a “dream”, a “vision” he was following, whereby economic or pragmatic considerations often fell by the wayside (case in point – the Jews contributed greatly to the wealth and economic flourishing of German society; Jewish brain power, such as that of an Albert Einstein, denounced as “Jewish science”, was also significant; but what was Germany’s loss, was America’s gain. Germany cut off its nose to spite its face, triggering a “brain drain” that played directly to the advantage of a more pragmatic America).
