Seven years after the Taliban, what's changed?

The Taliban in Afghanistan has launched a number of successful attacks in recent months, but some argue that the way to really calm the country is to reform the Afghan government from top to bottom. Also, the U.S. is considering how many more troops to send to Afghanistan, perhaps rotating some brigades from Iraq.
