One problem though is the very real possibility that Germany fell to a Bolshevik Revolution, it probably would have happened if not for The Freikorps. Unfortunately The Freikorps were the seed that eventually grew into the Nazi Party.
Many of them, tragically, yes. Although a few of them actually joined the Resistance later on.
But the Nazis, alas, did manage to rally the political Right to its cause.
I think the Nazis were not left nor right, but both. This ideology was an infernal dualism of Nationalism (i.e. here: anti-Semitic hatred and imperialism, not a moderate Nationalism) and Socialism.
Unfortunately, just before the elections in 1932 and 1933 they had toned down their Anti-Semitism significantly - in public, as they knew that would not be a big vote-winner.
The wolves had been eating chalk, as we say in German (an allusion to the fairytale of “The wolf and the seven little kids”, where the wolf eats chalk to get a sweet voice, in order to trick the little kids into opening the door for him).
P.S.: Hmmm...devious politicians? Unfortunately, deception in politics, especially before elections, didn’t simply disappear with the fall of Nazism. It is still fiercely clinging, alas, to life.
