Thanks for dispelling this oft repeated myth. So is your interpretation that Hitler was entirely authentic opposition? There are other anomalies, such as:

• the role of the Vrill and Thule societies in his rise to power
• shared symbolism between the Nazis, Freemasons, and Theosophic Society (such as a shared reverence for the swastika)
• funding of the Nazis by the American establishment
• the assimilation of the Nazis into the American intelligence community and NASA
• Hitler's disappearance which leaves open the possibility that he escaped, and possibly wasn't personally in danger
• the fact that the Allied forces deliberately left weapon plants intact, indicating that a hidden power meant for the war to go on for a while.

Based on these facts, I cannot exclude the possibility that Hitler was controlled opposition.
