You're probably right....I hadn't thought about that...but, there probably will be many Iraqis hiding for months after we've gotten rid of Saddam and his ilk.
From the reports coming in, the fedayeen are at least half non-Iraqi (Bob Arnott reported this today)--they're coming in from Syria and Jordan (probably Palestinians, probably Hamas and Hezbollah), Sudan, Egypt and other countries with large Sunni populations--and a possibility some are al Qaeda or with al Qaeda affiliated groups. Arnott reported these were the fiercest fighters, probably because they aren't from Iraq, have no place to go home to and define natural born killers.
