But what % of suicide bombings in Iraq are sponsored by Al-Zarqawi? I thought it was known that he, a Jordanian, heads up mainly foreigners? And isn't he a Bin Laden type Sunni, so any Iranian Shiites would not be fighting under him. My understanding was that Al-Zarqawi leads the most extreme and headline grabbing of the insurgent groups, but I'd be surprised if his people account for the majority of the attacks.
