<<Could it have been true that the Kaiser lost WWI because Jewish bankers refused to lend him more money? There are several factors here: first, did they actually control sufficient funds to have made a difference; and second, did they deny the money to the Kaiser at all? There is not a lot of evidence that either was the case.>>
That was a new one for me, XO. The usual bullshit was that the Jews administered the stab-in-the-back so that their more financially powerful British banking relatives would be able to suck the blood of the German workers through reparations payments following the war. There was a powerful and growing socialist and communist movement which was international in nature, the extremes of which were recognizing class loyalties as more binding than national loyalties. So the war, which like all wars, was fought for the benefit of the ruling classes of all the combatants, was fueled by the blood of the proletariat of all combatants. Instead of the proletariat killing each other off for the benefit of the ruling class (usually the bourgeoisie) they should refuse to fight each other at all and concentrate on assisting each other to seize the power in each of the combatant nations. The right-wing argument was that the leadership of the international socialist movements was mostly the Jews and their dupes, who by "blood" belonged to none of the combatant nations but to their own supra-national nation which had no land of its own, but was distributed, parasitically, in the bodies of its hosts, which it was consuming from within. This was basically the myth of "The International Jew," the title of Henry Ford's book, which was said to have had a major influence on Hitler, and popularized in the U.S. by Father Coughlin, a Roman Catholic priest whose weekly radio show reached millions and, like Hitler, was one of the early adapters of radio as a means of spreading political ideas.
The big argument the Germans had going for them was that the war ended with German troops on French territory, not vice versa, so that the "victorious" German army won the war but was "betrayed" by stab-in-the-back German civilians and their "communist" revolutionary activities, which were actually just a front for the international Jewish banking network.
Of course, the reality was that the Jews in each of the combatant nations shared the benefits or the burdens of that nation's fortunes, however it would be less evident in the defeated nations that the Jews there were suffering like the rest of the population, since the Jews, probably due mostly to their cultural traditions, were always better at looking out for themselves than the general population and were better prepared to deal with the adversities of the defeat. But that's a pretty boring story. The idea of a world-wide conspiracy of hook-nosed aliens is much more entertaining and gives the average guy leading a dull miserable existence an exciting fantasy role to play, like a science fiction hero, he can combat these alien infiltrators and save his "race" (without any physical danger to himself) by joining the Nazi Party, getting a uniform, marching like a soldier and having a beer or two with the guys. His racial identity alone gave him instant drinking buddies, a role to play, a mission in life and a clearly delineated hierarchy of quasi-military ranks through which he could progress if so inclined. The marketing was absolutely brilliant.
