The Taliban, broadly speaking, are Afghans - farmers, subsistence farmers. As I say, most of those people can't find the United States on the map. Al Qaeda, traditionally, are much more educated, middle-class people, often from Egypt, from Saudi Arabia, North Africa.
It's one thing to be writing in South or Latin America, where, except for Brazil, every country, however small and hard to find on a map, speaks Spanish, but quite another to be writing in, say, Hungary, a landlocked nation of 10 million people, with a language that very few people outside Hungary can read or speak.
