The argument "Iraqis are not children.." can just as well be applied to Afghans. And I am guessing you support the deployment of additional troops to Afghanistan, even though they too, will not step up and assume responsibility in the presence of US troops.
US troops in Iraq are not there to provide guidance ~ they are there to provide security, so that the Iraqis can fix their own house.
As a matter of fact, I do favor putting more resources into Afghanistan. It has been neglected for too long. We need to put more resources into rebuilding the country. We also need to put more effort into capturing bin Laden. That will require more troops.
