So because it is difficult and fraught with past failure, we shouldn't do it? I don't really see how anybody could pose a logical argument for allowing a terrorist government to control a country.

We already completely dropped the ball on Afghanistan once and it wouldn't surprise me if we do it again, but if a country is being used to train an army of extremists bent on the destruction of the free world... well, somebody should probably look into stopping that. And I don't think saying "please" works on those people.

Then again, maybe I'm wrong. Maybe if we never invaded Afghanistan and overthrew the Taliban-controlled government, everything would be peaches right now. I certainly wouldn't have wasted a year of my life in the shit hole. But that seems like the riskier road to take, given what I've learned on the topic.
