The taliban movement is a fundamentalist islamic movement; "taliban" means "student", implying "of the faith". They were uh, very naughty when it comes to human rights (like really very naughty), and then helped/hid Ben Laden. This angered the USA, who punished them severely - by attacking them, I believe in 2001, with an international coalition (war against terror). That's the official version, at least.
A more critical approach would involve analysis of the strategical location of the country; during the Cold War, the two blocs were heavily involved in the area, and it's some kind of border between worlds - the Western/westernized world, the South-Asian world, Russia, etc. Everyone wants control of that place, which is a big reason for invading them (them generally governing in a terribly repressive manner just adds a layer of legitimacy). However, the people there happen to be Muslim in a quite traditionalist manner, which is why the taliban were strong: they had the support of the people, at least in rural regions. Thus, it does sound like Afghanistan's takeover of Afghanistan because that's what it is for a significant part, sadly. It's not only that, though, since there was a liberalization process going on in cities (I say in cities because rural areas are de facto governed by tribe leaders who do whatever the hell they want lol, to say it broadly). That means women holding power positions and not being under hijab 24/7, for example. This is very probably going to end.
Afghanistan was an invasion that ultimately failed; the guerilla warfare applied by talibans was the way to go, it seems. If the people there don't change their mentalities significantly enough, sending tanks won't do much.
