<<Can we drive them out of Afganistan or just drive them underground?>>
They're fanatics. You have to kill them all or they'll just keep coming back. And you have to assume total control over the education of the children and young adults for at least 35 years to make sure the same poison doesn't get re-injected all over again. It means (God forbid! Gasp!) you gotta teach the little buggers evolution.
<<Can we save Afganistan from the Taliban somehow , but hand Iraq over to the same hing?>>
The Iraqi Resistance is not the Taliban, plane. Not even close. They're Sunni but a lot more secular.
