The success of the Nazis is based on their use of a mineral named lunarium, which has the ability to lower the IQ of human males drastically, thus effectively preventing military resistance when the Nazis invade. The lunarium is dropped in the form of bombs from a fleet of zeppelins flying at a higher altitude than anti-aircraft guns could possibly reach. What is even more puzzling is that lunarium is - as the name indicates - only mineable on the Moon, and mankind so far does not yet have the technology to reach it.
