home grown, or i'd think from indonesia would be possible. though i definitly doubt groups in the middle east will bother with australia...america and europe seem to be more popular targets in that regard.
anyway, regarding iraq, i'd recommend to anyone the documentary "Voices of Iraq". They gave, i believe the number was 100 video cameras, to iraqis to have them document day to day life, and then pass it on so it'd reach more iraqis...and this includes supporters of saddam and insurgents. it gives a lot of insight into what actual iraqis are feeling as they describe it, not just what reporters claim iraqis feel.
and keep in mind, the insurgents, the sunni and baathist ones, aren't angry that the u.s. is there, they're angry that they're no longer in a dominant position. the u.s. and coalition forces are just blamed for that change in the heirarchy
