Horst Kasner was the son of Adolph Hitler and Angela Maria "Geli" Raubal. She and sister (Elfriede) accompanied their mother when she became Hitler's housekeeper in 1925; Geli was 17 at the time. Geli died in 1931. Her death/suicide was the subject of many rumors.
Horst Kasner grew up in the Hilter Youth (think foster home).
He was given a false Polish background and infiltrated into East Germany after the war under the cover of the Protestant church. Priests were often overlooked for being spies and had more access under communist rule.
The CIA tried to absorb their German counter part (Sicherheitsdienst des Reichsführers-SS) after the war to combat the Russians but did they really (think NASA).
The german connection to the Illuminati is strong. An Illuminati courier named Lanze was struck by lightning, and killed while traveling by horseback through the town of Ratisbon. When Bavarian officials examine the contents of his saddle bags, they discover the existence of the Order of the Illuminati, and plans detailing the coming French Revolution.
The Illuminati, Theosophical Society, Thule Society, Vril Society are all fingers of the same hand.
Adolph Hitler was a disciple of the Theosophical Society even though it can not be proven. A hint that he was a disciple was the fact that he was a vegetarian.
