I basically agree with Ahmadinejad's strategy, which is to ballast the absurd interpretations of history that continue to "justify" the occupation of Palestine. There is a Legend of The Holocaust that differs signicantly from the facts. It's definitely revisionist. He's doing himself a bit of a disservice by choosing the term "Myth" - if that is indeed how the Persian word accurately translates.

The Auschwitz jibe, instead of going for Mauthausen (which would have been the really legend eviscerating move - given that fewer than a third of the camp's victims were Jewish) also weakens what would have been an easier win. But I think Iran has good relations with Austria.
