One of the more interesting blogs that I have come across covering the insurgency in Iraq is John Robb’s Global Guerrillas.
Thoughtful analysis, mostly devoid (from what I have seen) of a partisan agenda, it is a cerebral supplement to Intel Dump.
Have a look at the graphic accompanying The Bazaar Of Violence In Iraq, above.
Please use the comments to demonstrate your own ignorance, unfamiliarity with empirical data and lack of respect for scientific knowledge. Be sure to create straw men and argue against things I have neither said nor implied. If you could repeat previously discredited memes or steer the conversation into irrelevant, off topic discussions, it would be appreciated. Lastly, kindly forgo all civility in your discourse . . . you are, after all, anonymous.
