[Roberts writes in support of the views of David Irving on World War 2 and the Holocaust, writing that "David Irving, without any doubt the best historian of the European part of World War II, learned at his great expense that challenging myths does not go unpunished... I will avoid the story of how this came to be, but, yes, you guessed it, it was the Zionists".[42] Roberts writes that "No German plans, or orders from Hitler, or from Himmler or anyone else have ever been found for an organized holocaust by gas and cremation of Jews... The “death camps” were in fact work camps. Auschwitz, for example, today a Holocaust museum, was the site of Germany’s essential artificial rubber factory. Germany was desperate for a work force."[43]QUOTE]
