Yeah, I never heard Bush use "womens rights" as a justification for overthrowing the Taliban...
Bush uses womens rights in Afghanistan in every campaign speech he makes. Afghanistan is a success, in the Presidents view, because girls are going to school. Its probably true that the most extreme Taliban policies have been reversed. But its also true that the Government of Afghanistan only controls Kabul. The rest of the country is ruled by tribal warlords, and some of them are as repressive in their treatment of women as the Taliban was.
