America did nothing of the sort - America bought off the Taliban not the Northern Alliance (which came to bite us in teh ass at Tora Bora). Russia had the good intel on the Taliban not us.
There was a bunch of reports in the MSM (e-ek!) about Green Berets inserted with the Northern Alliance and disbursing cash, in the beginning of the campaign, with the warlords holding out for more. Thus I disagree - we did a lot of the sort.
