In a 1990 interview, Nolte implied that there was something to the Leuchter report: "If the revisionists deniers and Leuchter among them have made it clear to the public that even 'Auschwitz' must be an object of scientific inquiry and controversy then they should be given credit for this. Even if it finally turned out that the number of victims was even greater and the procedures were even more horrific than has been assumed until now." In his 1993 book "Streitpunkte" ("Points of Contention"), Nolte praised the work of Holocaust deniers as superior to "mainstream scholars". Nolte wrote that "radical revisionists have presented research which, if one is familiar with the source material and the critique of the sources, is probably superior to that of the established historians of Germany". In a 1994 interview with "Der Spiegel" magazine, Nolte stated "I cannot rule out the importance of the investigation of the gas chambers in which they looked for remnants of the process engendered by Zyklon B", and that "'Of course, I am against revisionists, but Fred Leuchter's 'study' of the Nazi gas ovens has to be given attention because one has to stay open to 'other' ideas."
