Zarqawi not al Qaeda?

Now we learn that Zarqawi, the most dangerous man in Iraq, may be a rival of bin Laden trying to create a competing terrorist network. The man suspected to be behind the beheadings, Zarqawi's currently hiding out in Fallujah or so we believe. Bombs are being dropped to flush him out, but thus far, the accuracy rate is the same as that of the "Saddam Killer" missles (that we now learn killed a whole lot of civilians instead).
