has anyone seen an estimate or hard numbers on total "insurgent" casualties ?
Well, I haven't seen numbers about terrorist casualties, but I remember that at the beginning there was estimates of some 15 to up to 40,000 terrorists.
Gen. Abizaid said that based on the attacks on the day of the Iraqi election, when the terrorists "pulled out all the stops", they estimated that there are only around 3,500 terrorists around.
You do the subtraction.
I think that some actually gave up and blended into the population and "gave up their evil ways", but I bet a lot of them are no longer with us.
