Iran’s President in an interview said paraphrased, his way of trying to start talks on Israel and Palestine conflict was through the conference he initiated in December 2006 in Tehran titled something in lines with: International Conference to Review the Global Vision of the Holocaust.
The goal according to him was not to deny or prove the existance of the Holocaust. Further though, the Iranian Foreign Minister said: “If the official version of the Holocaust is thrown into doubt, then the identity and nature of Israel will be thrown into doubt. And if, during this review, it is proved that the Holocaust was a historical reality, then what is the reason for the Palestinians having to pay the cost of the Nazis’ crimes?”

What Iran’s true motive with this conference was, only they can answer, but here is a related story that I would like to share.

“This story was aired on Sunday, Dec. 17 on CBS on 60 minutes about a long-secret German archive that houses a treasure
trove of information on 17.5 million victims of the Holocaust. The archive, located in the German town of Bad Arolsen, is massive (there
are 16 miles of shelving containing 50 million pages of documents) and until recently, was off-limits to the public. But after the German
government agreed earlier this year to open the archives, CBS News Scott Pelley traveled there with three Jewish survivors who were able
to see their own Holocaust records. Its an incredibly moving piece, all the more poignant in the wake of this weeks meeting of Holocaust deniers in Iran.”
