Actually it was mostly aided by westerners driving cars. Vast amounts of oil money were used to open and support the Madrasses across the Pakistan/Afghanistan border which in return helped those groups in the area including the Taliban.
I do have to agree with JJ in one point, Intelligence Agencies about the world helped to create the moster that has now turned on them. The main culprit was the ISI, Pakistans, but the CIA bears some responsiblitity in that they knew that the ISI was targeting the Afghani radicals for the majority of funding and they ignored it. Saudi Arabia bears blame for the rise of Bin Laden and his group because of their using, funding, and then discarding of him when he went rogue. Telling him that the US was out to kill him to get him out of the country before the US even knew about him didn't help a lot either.
There is plenty of blame to spread about though. No one group created Fundametal Islam, it has roots in many things, but mostly in a dark ages type mentality that says we should all be living lives like theit prophet did, that moderisation, westernisation, and human government are evil and ungodly, and need to be destroyed. Unfortunately the very people that these groups target unwittingly gave them the ability to do exactly that because at the time they faced a bigger monster and they were too short sighted to see the future once that monster had been destroyed.
