The terrorists are probably not Iraqi. They are probably foreigners terrorizing foreigners. If the foreign terrorists had a mission or a terror to cause they probably need to do it now because in a few days the Iraqis will be taking care of business. Iraqis can smell a foreigner six blocks away.
Yes, "terrorists in Iraq" might be a better description. Though, one should believe that Zarqawi is gathering lots of home grown boys into his fight at this point. They very well may be Iraqi by origin.
