Just sayin', Hitler didn't even invent the jew-stuff. It has been done throughout history, poisoned wells and all. The whole region in central europe was tense as fuck at the time, even before WW1. Adolf was just as shaped by his surroundings and history as PigBoss is by 4chan and shitty memes, so to say. If the suspicion hadn't been widespread already, that particular thing would most likely have failed. Hitler only amplified what was already in people's minds, and played to their fears. He did a pretty good job, all things considered.
