In fact Zarqawi the first leader of Al Qaeda in Iraq was sent by Bin Laden to Iraq from Afghanistan in 2002 to establish Al Qaeda branch there. If your colleague does not think that Zarqawi was part of Bin Laden Al Qaeda, I have an Al Qaeda document which clearly states that Zarqawi was one of the Al Qaeda leaders in Afghanistan.
Now ask your colleague what is his proof that Al Qaeda in Iraq is not Al Qaeda of Bin Laden despite that Bin Laden and Zawahir say so all the time and despite that Zaraqawi was sent by Bin Laden to establish Al Qaeda in Iraq.
