The idea of "peace" in a completely Muslim world is laughable if it weren't so serious. The Sunni, Shia, Wahhabi, Salafists, all together in peace.
Riiiight. We can see how well that works in Iraq. They would continue to kill each other ad infinitum. It's the one and only Religion of Peace®.
“Before I was nine I had learned the basic canon of Arab life. It was me against my brother; me and my brother against our father; my family against my cousins and the clan; the clan against the tribe; and the tribe against the world. And all of us against the infidel.”
