Nazis are pretty dumb yeah, you see the entire Nazi war effort in WW2 is very... Nazi-like. They took power in Germany and in mere years they invaded everyone they could without doing the preparations needed for it but don't worry because my superior ideology and race will make up for the economic and military shortcomings, also I have BIG PANZER and BIG KANONE which will make the enemy tremble before us. When you read about their actions in the war, their planned offensives, their economic policies in wartime and stuff, you see Nazism leaking through the gaps. It's really stupid and lacks logic, like believing they would defeat the USSR in one or two months because "subhuman slavs", or how the Jews controlled the world despite being the "inferior race".

The special type of dumb Nazi is the one who believes in the occult, in the Thule Society (which predates proper Nazism but many original Nazis were heavily influenced by it), the Black Sun and shit like that. In other words, those who joined the SS not for military reasons but for political-mysticist reasons, because they liked to hear Himmler preach about esoteric shit or something. That's a special kind of dumb nazi, weebs for everything Nordic but heavily twisted to fit their Nazi identity. Curiously enough, Hitler wasn't interested in this crap, he used to ignore Himmler when he spoke about these societies and shit. This kind of belief system is what constitutes the core of many neo-nazi groups today, which is interesting to say the least. For example, see the neo-nazis opearting in Ukraine right now, they all recycled these old and quite niche symbols like the Black Sun or the SS-like runes. Do they truly believe in secret societies and stuff? I don't know, but the fact these symbols and meanings managed to survive the entire post-war era and find their way into modern nazis is interesting, and certainly contributes to them not being the smartest bunch of people.
