Potential History is just an arrogant redditor cunt that puts a bunch of conjectures filled with memes for his vids. He has no idea what the fuck he's talking about either (I.E. thinks Germany winning in France was a miracle, thinks the shitty spam tanks of the Soviets against Japan was some big ass defeat in Nomonhan, has a very retarded opinion of why Germany lost the war). His vids are just memes that shouldn't be taken under any consideration when he comes off as a butthurt anti-Wehraboo. There's actually a video out there of Ryan Faulk refuting one of his videos.
I think his most retarded take was complaining that all the footage of the German armed forces during WW2 stems from wartime propaganda, and has therefore colored our view of the German military during the war. Like dude, all the footage of every army during the war comes from propaganda. In fact the Germans were better than a lot of the other warring sides to actually get footage from the front. The Soviets would actually film a lot of their footage after the war, as there was a wartime shortage of film crew equipment and not really a domestic market for war time propaganda films.
I'm sure it was annoying 10 years ago when Wehraboos would constantly proclaim the German army to be the best in every category and shit up every internet discussion about the war. But the pendulum swung so hard in the other direction that mouthbreathers like Potential History keeps coming up with these reddit tier takes.
