Errr this isn't a conventional war.
The conventional military has been defeated.
Iraq is defeated.
A UN force should be sent to occupy.
There is however still a terrorist threat to defeat.
Conventional forces do not perform well against "guerilla" tactics.
Rome suffered defeat using the best trained military of the period against many barbarian nations utilising thick forests or other unconventional military tactics.Britain lost to guerilla tactics in the War of Independence , and the US performed badly in Vietnam.
Special Forces Cells should now be authorised to seek and destroy.
SAS officers killing terorists in the streets of Gibralter proved very effective
