I think you're working too hard to define the insurgency...though I agree that some of them are as you have noted, at least those who are not from Iraq.

However, the number of insurgents, Iraqi insurgents, if they can be called such a thing, didn't really take off until all the Iraqis were put out of work...left out of rebuilding their own country...no money, no water, no electricity, no sewers, no telecommunications, and an easy and obvious target for their desperation...the contractors working for U.S. corporations, and the Coalition soldiers.

I agree on your definition of symbiosis, but disagree that the Iraqis are getting a mutual benefit...they're worse off than they were before the war, in many ways, and the occupiers are rightly seen as the cause of that.

Fish on...
