The opportunity for the Nazi's to gain power was largely manufactured by the Treat of Versailles.
After being crippled financially by the allies post WW1, when Adolph started screaming about making Germany great again and binning the Euro leeches it sounded very attractive to the voting public (sound familiar).
Also right wing movements were prevalent all over Europe at the time, we had ours, if the wind had blown a different way we could have easily ended up allies with the Nazi's.
That's all true, but I'm not sure what your point is.
