america never directly funded bin laden, they funded pakistan who funneled the money to mujahideen jihadists (and later the taliban)  within that group, bin laden was a part of the arab mujahedeen, and they were mostly funded by rich saudis, by bin laden himself, and by muslim charities. yes, sometimes the american money ended up in their hands, and obviously the arabs benefited from the american funded strength of the wider, afghan mujahedeen. but overall the arabs had their own money
