The problems in Afghanastan aren't so simple because there were many factions fighting. It's been stated in texts and is my opinion that part of the reason the USSR were fighting was against the rising Muslim fundamentalism because they have a great deal many Muslims in their country as well as other things. But again, there were really several factions including at the start someone named Amin (?) who was head of the country and then later also Prime Minister (when that person was killed and so took both roles) and who was actually educated in the USA. Also, the UK supplied blowpipe missiles through the CIA so you can see that's it's not just the USA and the whole thing is a crazy mess.
This is just one one-hundredth of the whole story (which I don't completely understand and readily admit that) and my point is to show it's not always so easy to state things so simply like it's being stated. Supporting Bin Ladin specifically, I don't think so.
Just like we supported Iraq during the Cities War but we also secretly supplied Iran as well. However, Iraq flew a great many French-built fighters and received some during the conflict. These things are not always the USA in isolation.
