Sistani for peace prize

"A group of expat Iraqi Christians in the United States launched a petition to nominate Al-Sistani for the 2005 Nobel Peace Prize."

And

"I did sign the petition to award Ali Al-Sistani the Nobel Prize for Peace for 2005.

I believe that awarding the prize to him will inspire many Muslims to see what he advocates. As the petition states, "Al-Sistani has helped Iraqi society to avoid civil and multiethnic violent conflicts that terrorists intended to draw, and by this he has promoted peace and respect to human brotherhood in Iraq, the region, and all over the world.""
Abbas Kadhim

Wow two Iraqi blogger that I respect from opposite sides of the spectrum have both independently signed this petition. I had already commented that I find it a bit weird that the most reasonable guy in today's Iraq, was the Ayatollah, with Abbas endorsement I was thinking about signing, but if Fayrouz signed it too, I feel like I'm missing out on a good thing...What to do....I know that I have been surprised by many things I have heard form Sistani, But can I sign?
