If the Saudi intention is to participate in the coming war against Iran it will be making a big mistake. Such a move would require the introduction of conscription and the induction of thousands of young Saudi nationals - many of whom have posters depicting Osama bin Laden on their bedroom walls - into the military. I don't think those young guys are going to be pointing their guns at the Iranians. They'll turn their guns on the crumbling House of Saud and its allies (that means us folks).
I also agree that reading biblical stuff on Rueters is decidedly weird.
