“The term "Fourth Reich" has been used in a variety of different ways. Neo-Nazis have used it to describe their envisioned revival of an ethnically pure state, mostly in reference to, but not limited to, Nazi Germany. Others have used the term derogatorily, such as conspiracy theorists like Max Spiers, Peter Levenda, and Jim Marrs who have used it to refer to what they perceive as a covert continuation of Nazi ideals.”
