Over the past year, we've witnessed an ever growing tide of anti-Semitism and holocaust denial in the Muslim world: Iran's outgoing president Ahmadinejad citing Holocaust denial as his "greatest accomplishment", an Islamic rally in Pakistan, with marchers carrying signs that read "God Bless Hitler"...the list goes on.Meanwhile, a very different story was quietly unfolding. Muslim clerics from all over the world were leaving their homes to embark on a remarkable journey of compassion and reconciliation. Their destination: the Nazi death camp at Auschwitz.For a week they sat and talked, with each other, with survivors, and with those who hid Jews. They learned, they wept and they prayed for the dead. And when it was over, they courageously declared, in writing, their condemnation of holocaust denial and anti-Semitism wherever they may happen.The transformative power of the Imams' pilgrimage was evident. But two questions were on our minds as the journey ended: What would they do with the newfound perspective they'd gained? And does this kind of dialogue have the power to change our world?Over the coming months we will follow the Imams home, to document first-hand the ripple effects of their experience on the communities they lead.
