I don't think its quite working like that, for one does anyone realise what a horrible stratergy that is ?

Imagine your country be used as some kind of slaughtering ground for some other countries enemys.

Secondly i think we started with a far smaller pool of extremists, sure some of the original pool have been killed, and a load of the new terrorists we've created are dead now too, but the problem is what we are now left with is a much bigger pool of exremists, and the possibility if we don't manage to stabilise Iraq that the place will become something like Afghanastan before we arrived, a breeding ground for terrorism...
