The Nazis did not really lose World War II.
They made it appear that way in order to divert attention from the alliance between the Fourth Reich and the race of aliens known as the Reptilians—an ancient galactic civilization obsessed with conquest and domination.
After the German surrender in 1945, the Nazi-Reptilian alliance infiltrated the U.S. military-industrial complex.
Through "Operation Paperclip," the Nazis and Reptilians removed their political opponents, such as the Kennedys, and moved into policy-making positions in post-war America, infiltrating aerospace companies, banking, media, and the U.S. government, including NASA and the CIA.
But their real target was not the United States—it was the solar system.
