That's revisionist history! The Taliban hosted a group that attacked the US. We asked them to give up the group. They denied. Then we took them out. The nation building effort came after the needed invasion.
I have revised nothing.
The Taliban were willing to work with the US. They merely asked for evidence that the things the US said were true.
But the US does not need evidence to do the things it does. Nor does it provide evidence to support the claims it makes.
So rather than try to find some peaceful alternative the US attacked and also decided nation building was a good idea despite the fact that GW specifically said in the debates that US nation building was a bad idea.
No--they wouldn't have handed him over even if we proved he was responsible. They didn't even have the ability to hand him over if they wanted to! It was just a distraction to muddy the waters and fool those who don't look carefully.
