We also have the idea of Space Nazis which was proposed by insiders such as William Tompkins who worked for the US Navy during World War II, and said he was part of a Navy espionage program that monitored the Nazi’s flying saucer program. Tompkins asserted that the Germans successfully established a breakaway colony in Antarctica which became a space power over the succeeding decades.
According to Tompkins and other insiders, the Germans have established colonies on Mars, Ceres, and elsewhere in Deep Space, and have developed some of the most advanced aerospace technologies known to humanity. Given their non-state status, the breakaway German Antarctic/Mars colonies may also be considered a modern form of space pirates.
Finally, we have the idea of a transnational corporate network that has developed its own space fleet that operates outside of any national or global institutional authority. According to insiders such as Corey Goode, the Conglomerate has the most advanced spacecraft in existence as a result of their long-time cooperation with the breakaway German group in Antarctica.
