Fun with links folks.. Sorry, I got a little carried away with google. I've seen a lot of discussion, but not a lot of posting of links so I thought I'd help.
My short opinion, the US has been very short-sighted in supporting some groups. As mentioned in a previous post, the whole 'the enemy of my enemy is my friend' attitude falls apart when the main enemy is no longer present. Then we're stuck with an enemy that we have financially or logistically supported. Oops.
On the subject of us flying the bin ladens out of the country, big deal. I think we realized that the family is not the enemy. Maybe Bush's prior oil dealings with the Bin Laden family had something to do with it too
Have fun reading!
NOTE: I don't believe everything I read on the internet. Just because it's posted on a page doesn't make it true. I'm not sure about these sites individually and I make no guarantee that they are a credible news source or some 'joe blow' conspiracy web site.

While the American government admits that it funded Afghanistan and assisted in training some Afghans, the official line - so far - is that it did not train bin Laden personally.
