I would also like to add that, while I do understand the use of "Iraqi" to mean "those fighting on the side of Iraq," remember that Al Qaeda is not doing so. They are fighting for fanatical pan-Arabist and indeed pan-Islamist extremism. The fact that they hitched this beheading to the prison abuse scandal doesn't mean they are fighting for Iraq; they were committing such atrocities, including 9/11, when they were open enemies of Iraq. They are opportunists, and will claim to be defending the Iraqi people against American aggression, so they can mislead innocent Iraqis. If this was indeed Al Qaeda, we should NOT confuse them with "Iraq," or assume that things we do to innocent Iraqis will avenge acts committed by Al Qaeda, even if Al Qaeda is now, in the wake of our disastrous invasion, infiltrating Iraq.
