As with any invasion of a country and coordinated miltary operations, there are a complex data set of reasons. I think that one can argue that the American interest in Afghanistan in 2001 centered on the pursuit of Osama bin Laden and other high ranking Al- Qaeda officials that took refuge in Afghanistan. At the same time, credible intelligence indicated that many Al- Qaeda training camps were located in the nation of Afghanistan. Along with this, the Bush Administration understood the Taliban as an overall threat, making the invasion of Afghanistan a matter for international well- being. In seeking a coalition approach to the invasion, England joined the United States. Britain supported all of the rationales offered by the United States, but also believed that the opium poppy reservoir of growth in Afghanistan also necessitated invasion. Prime Minister Tony Blair argued that the opium produced in Afghanistan was being smuggled onto the streets of London and all over England, necessitating action in protection of domestic welfare. These reasons ended up justifying military action against Afghanistan in 2001.
